    A pair of LS3/5A started on eBay last week at something like -u9.99. They
    went in the end for well in excess of -u1700!!!

    Mate from Uni made some (1985?) from Wilmslow Audio driver/crossover
    kits. He was very good at woodwork so the cases were beautiful. They
    sounded rather good especially when you consider how tiny the bass
    driver is in them.

    It's what's called a cult-following. Lots of stuff about these on
    t'internet e.g. https://www.theabsolutesound.com/articles/falcon-acoustics-bbc-ls35a/
    the Wiki article is good: https://en.wikipedia.org/wiki/LS3/5A

    If you have a pair, sell them for the best money you can get. As you
    get older your hearing won't be up to needing the best hifi anyway.

    To be fair, by definition all hi-fi is overrated.

    "High"

    I propose a new class,

    "Ample Fidelity"

    Stuff that does what it says on the tin.

    Bluetooth speakers mainly. Streaming.

    No need for collections, components, stack systems, midi systems, music centres, radiograms etc. Folks used to dedicate a room, space, that mess
    of wires in a corner now replaced by a pot plant.

    And they can enjoy the efforts of songwriters, singers and musicians and
    not the marketing whims of the dancing circus capitalists pretending ye
    need this and that for the "ultimate".

    Yeah, I enjoy messing with audio electronics technicals and it's
    nostalgia - but for today like a load of other pastimes from the last
    century, just recognise it's going nowhere as a future business.

    A bluetooth speaker is a popular current replacement for a Hifi.

    Some sound OK, Some sound like "who cares?"

    You stream to it from a mobile phone.

    A bluetooth speaker is a popular current replacement for a Hifi.

    A combination of decent speakers with a quality amp is going to be rare in
    such a device, which is why one might stick to separate speakers, separate
    amp.

    Although I suppose it's possible someone might do a proper job, but not much change out of -u5k I wouldn't have thought.

    There are many examples of nonsensically over-rated products available
    in the hi fi biz. The LS3/5A is one of them. We all need loudspeakers to listen to audio (unless you happen to use headphones, of course).

    I've listened to the LS3/5A many times (different manufacturers). I hear
    the same problems with all of them. They are, quite simply, highly
    inaccurate speakers. IE: They are not high fidelity speakers.

    There wasn't a lot wrong with the Quad 33/303 combo I bought in 1970. No optical or other digital input, of course. Especially when paired with the IMF RSPM I bought in 1974. Not that I could tell, these days, of course, but I

    Quad 303 was relative junk actually. Had a lot of crossover distortion especially at HF. Many of its contemporaries were in fact better.

    Things got better with the advent of audio power FETS and/or class AAB designs.
    As transistor speeds went up the problems of maintaining high levels of feedback at high frequencies without instability, lessened.


    Today even the class D's will beat a Quad 303

    **True enough. I use an amplifier that is now 40 years old. Obviously,

    some expensive modern amps.


    Loudspeakers never have been. They are all compromises of one sort or another.

    **Also true enough.

    10M. Wonderful speakers. The technology used is based on stuff developed
    by Bozak way back in the dark ages. Oh yeah, they eat LS3/5As for
    breakfast. Largely because, unlike the LS3/5A, they are accurate. Not
    quite as accurate as the ESL63 though.

    The LS3/5A was faulty when it was designed and it is just as faulty today.

    There wasn't a lot wrong with the Quad 33/303 combo I bought in 1970. No
    optical or other digital input, of course. Especially when paired with
    the IMF
    RSPM I bought in 1974. Not that I could tell, these days, of course,
    but I
    sure could then.

    Quad 303 was relative junk actually.-a Had a lot of crossover distortion especially at HF. Many of its contemporaries were in fact better.

    **Agreed. The 33/303 were, at best, extremely primitive, poorly
    performing products.


    Things got better with the advent of audio power FETS and/or class AAB designs.

    **Power FETs (V-FETs) were great. MOSFETs are horrible things.

    As transistor speeds went up the problems of maintaining high levels of feedback at high frequencies without instability, lessened.

    **Correct.



    Today even the class D's will beat a Quad 303

    **Today, Class D will beat most amps, given a reasonable load impedance.
    ESLs, not so much. Class D has a way to go in that area.

    Please explain why these are more suited to someone who has no
    interest in audio or is hearing impaired?

    I don't have your speakers but I do have two Play5s in the house.

    They're OK for background listening, compact and for many just fine.
    However, they're mono not stereo unless you get two in the same room.
    I've not heard of anyone doing that but I'm aware that you can. But
    in honesty they don't get close to our mini system let alone the main
    hi-fi for sound quality or detail or stereo image.

    The mini system is a Denon RCD-N9 and a pair pair of Q acoustic
    speakers. Sorry but it's better than Play 5s.

    I'm not criticising when I say if you were "into" hifi you would know
    that. As you're not into it, nothing I say will convince you only
    listening to a modern hifi system might but I wouldn't recommend
    that. You're happy with what you have, stick with it.

    Forgive the rant but you mentioned Sonos....

    The reason I smiled at you picking Sonos is I admit because they are
    a pet hate of mine. Not because of their sound quality but mainly
    because of their forced firmware upgrade policy. For that reason
    alone I wouldn't recommend them to anyone.

    Sonos force software/firmware updates on their customers by shutting
    down functionality of your devices until you update. Crucially, you
    cannot re-index your music library or make changes to network
    settings etc. all this is removed without warning several times per
    year. My hi-fi streamer doesn't do that. It informs me of an upgrade
    and lets me decide.

    You may say big deal, so what. Well it all goes pair shaped if you
    purchased something like an iPad to control the Sonos devices. When
    you update Sonos it frequently also updates the control point
    software on the iPad. Then Sonos insist that the iPad operating
    system is the latest version. All fine unless your iPad is a few
    years old and Apple provide no more updates. You are then stuffed.

    (Just in case you're thinking of it I'll mention that I'm aware of
    "sonopad" and it's peculiarities.)

    From having a gully working system one day to a crippled one the next
    without warning or choice AND the only way out is buy a new control
    device or a new iPad at u500 or so. That's why I hate Sonos.

    I also wouldn't choose them because they use SMB connections to a NAS
    and not UPnP from a server which means each device has it's own index
    and not the common one on the server. Finally because they will not
    play hi-res audio and most other streaming devices do these days.

    I've a Sonos One and an Ikea table lamp with a Sonos speaker built in. Both
    are good for what they are, and give decent easy to access sound. Although it helps that I've got an Alexa account and Spotify.

    While I still appreciate my 'proper' hifi I use smart speakers more often nowadays. Not sure why - just seem to get me to what I want to listen to at a quality I find perfectly good.


    Before lockdown I paid a visit to John Lewis and there was a
    Sonos rep in the store.

    I asked him how a single unit could reproduce a proper stereo
    image. His reply was that there were two speakers in it, a woofer
    and a tweeter.

    I went to a Hi-Fi show in Harrogate around that time but can't be

    and I had intended to stay overnight.

    I'm sure Quad, Kef, SME were there but my most memorable thing from
    the day was that there was a 'big band' playing in the theatre. It
    was great but I remember thinking - my father keeps telling me my
    music is loud and so was the music of his era.

    We found we completed the show quicker than expected and went into
    town were we found a branch of Comet. I purchased a new SME arm from
    there, the one you can unplug the whole arm tube from the bearings.

    Can't remember what the show was called but it was spread across several hotels. I do remember that Quad were at the Majestic.
    Per the big band - I remember walking along a corridor on the top floor
    at the Old Swan Hotel (remember, Agatha Christie disappearance etc?) and
    could here a band playing which sounded like Grimethorpe Colliery Band
    to my ears. I walked into the Ballroom and wow, what a sound - coming

    The best of the apps allow you to capture the sound and tell
    you which bird it is when you are back in mobils signal range.

    paired with the IMF RSPM I bought in 1974. Not that I could tell,

    Quad 303 was relative junk actually.-a Had a lot of crossover

    **Agreed. The 33/303 were, at best, extremely primitive, poorly

    Reconditioned Quad 33/303s certainly go fo a pretty penny. This dealer
    is asking u700, although bargain hunters can probably find them for
    half the price. I'm not sure I would pay that.

    * The Quad 303 amp was designed to be used with the Quad ESL57 speaker so had special features needed for that job.

    The exact right power output, +/- 33V peak as specified for the speaker - plus a regulated DC supply ensured this did not vary with the mains.
    Sharp low frequency roll of below 30Hz removing sub-sonic signals from TTs and LPs.
    Capacitor coupled output so never any DC offsets.
    Inherent current limiting protecting output transistors from accidental shorts on speaker lines.
    All the above combined made it safe driving the input transformer of the ESL57, a load of 0.3 ohms at DC or when driven into low frequency saturation.
    Few if any other SS amps of the 303's era included all the same measures and so could misbehave badly or fail or damage the ESL57.
    For this reason the 303 continued in production until 1985 when the ESL57 was withdrawn.
    Over 94,000 units were sold.

    **Yes. I neglected to add that. Phil is correct. A really high quality

    I've done a few blind tests, using relatively easy to drive speakers and

    Then later, valve hifi amplifiers came into vogue because they were stupendously expensive and fashionable.

    The big problem with early transistors were that they were not fast and
    could not handle high queisecentt power: that led to under biasing in
    audio class B and crossover distortion which sounds horrible at low
    signal levels. Especially at higher audio frequencies. The Quad 303 was
    an example,. It tested out ok at moderate power at 1Khz, but look at
    5hkz and a few hundred mW and it was awful.
    Once faster FETS came along and faster transistors this all became a
    thing of the past. A bog standard class D chip today will outperform a
    Quad 303 or a valve amp any day. For hifi and indeed for guitar *until
    you overdrive it*.

    Then the valves inherent low feedback/soft clip is a bit more melodious
    than a hard clipping tranny amp, but modern guitar amps actually do
    signal shaping before clipping anyway, to simulate valve overload. My
    'all digital' Fender can produce almost any sound you ask of it.

    No, it isn't. Not where it counts on a symmetrical class B output stage.

    to which the human ear does not object. IMSMC whilst
    much above about 0.5% third harmonic sets your teeth on edge, north of
    5% second harmonic is just not heard. Indeed a violin produces more
    second harmonic than fundamental and speakers equally have relatively
    high levels of 2nd and they don't sound too bad do they?

    Mostly crap. The reason valve amps sound better is that the overload
    more gracefully so cloth eared hifi nuts get less high order ODD harmonics.

    So 20W valve amplifier operating at 1% distortion will sound better than
    a 20W tranny at 1% distortion.

    But a 100W tranny operating at 20W will sound better than either.
    In hi fi apps.

    For guitar work the 20W valve will, all other things being equal,
    coupled to a suitable non linear response loudspeaker and cabinet, sound better than either, especially with negative feedback totally absent, Cf

    No, it isn't. Not where it counts on a symmetrical class B output stage.

    Agreed, a typical push-pull valve stage into a transformer will have odd harmonics.

    A singled ended class A valve output will have even harmonics. But these
    are rarely use as they are incredibly inefficient.

    For guitar work the 20W valve will, all other things being equal,

    Guitar amplifiers are all about distortion and harmonics!

    **Not so. It has been generally accepted that, under careful listening conditions, that humans can perceive around 0.1% THD.

    -aIndeed a violin produces more

    **Most musical instruments produce large amounts of harmonics. That does

    -aand speakers equally have relatively
    high levels of 2nd and they don't sound too bad do they?

    **Nope. High quality speakers typically exhibit low levels of
    distortion. In fact, some speakers produce lower levels of distortion
    than many valve amps.

    https://www.quad-hifi.co.uk/esl-2912/

    Distortion (100dB at 1m)-a-a-a Above 1000Hz 0.15%
    -a-a-a-a-a-a-a-a-a-a-a-a-a-a-a Above 100Hz 0.5%
    -a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a-a Above 50Hz 1.0%

    https://www.bowerswilkins.com/en-us/product/loudspeakers/801-d4

    Harmonic distortion
    2nd and 3rd harmonics (90dB, 1m on axis)
    <1% 30Hz - 20kHz
    <0.3% 100Hz - 20kHz




    The problem with loudspeakers in not distortion - at low sound levels
    they are excellent - its only when they are pushed to the limits of the
    cones travel that distortion increases. It is *resonance*. In practice
    you 'hear' the loudspeaker, not the music. This is perfect for electric guitars, as the loudspeaker is like the sound box of an acoustic guitar,
    but is its non ideal for hi fi.
    Hence the whole idea behind the KEF Bextrene cones. Stiff, and
    inherently 'dead' . And the idea behind multi element speakers, so that
    each speakers resonance was not where it was called to operate by the crossovers.

    The adage 'Carbon fibre destroyed the point of Bextrene' has an element
    of truth., A good soft spider roll surround CF coned bass/mid range car speaker is actually better than a KEF unit and can be had for a few
    quid. Or Kevlar honeycomb.
    Tweeters haven't changed much and plastic or metal domes are almost
    universal with maybe silk cloth domes for mid ranges.
    I personally will always be a fan of compressions drivers into loaded
    horns, and some of the JBL style mid range and tweeter horns we used in
    disco and PA applications were way cleaner sounding than almost any HiFi
    setup except perhaps Quad ELS, but could still kick out 115dB on the
    dance floor.
    And at very high power - well above domestic listening levels -
    distortion does become an issue as cones and diaphragms get pushed to
    the limits of their travel - compression drivers operate at far higher pressures and lower movements and do not distort at very high power indeed.

    But for domestic use a good selection of 3 ways bass/mid/tweeter is very adequate.,

    Mostly crap. The reason valve amps sound better is that the overload
    more gracefully so cloth eared hifi nuts get less high order ODD harmonics.

    **Somewhat crap. The reason why SOME valve amps are preferred over SOME
    SS amps is due to their overload characteristics. There have been and
    still several schemes that very effectively allow for 'soft' Voltage
    limiting (aka: clipping) in SS amps. Some schemes include:

    * A limiting circuit placed outside the feedback loop. (NAD et al)
    * A system which ensures that output devices are never allowed to
    saturate, combined with zero global NFB. (ME et al)
    * Some pro amps I've seen use a PTC element outside the feedback loop.
    * Digital systems also can be used.

    In fact, I've measured a few high(ish) global NFB, push pull valve
    amps that exhibit quite brutal clipping character.


    So 20W valve amplifier operating at 1% distortion will sound better than
    a 20W tranny at 1% distortion.

    **Again: That is a pretty broad claim, which is not necessarily true.


    But a 100W tranny operating at 20W will sound better than either.
    In hi fi apps.

    For guitar work the 20W valve will, all other things being equal,
    coupled to a suitable non linear response loudspeaker and cabinet, sound better than either, especially with negative feedback totally absent, Cf

    Class B can achieve 78%, at least in theory.

    The big difference is with the power dissipated at low and no output.
    It is at maximum with class A and near zero with class B.

    'Accuracy' isn't necessarily a problem, and trying to achieve it - at least in most domestic settings - is a fool's errand.

    I'd suggest the main issue is how good they sound to you, in your listening environment.

    Of course such a measure can easily become coloured by perception, marketing, reviews etc. But hey, if you enjoy the sound . . .

    That reminds me of when I was developing am audio amplifier for a German loudspeaker company, They sent their golden eared boy over to blind test
    two possibles. He unerringly picked the one with more crossover
    distortion 'because it sounded like his Revox'. I tested that as well.
    That too had high levels of low volume crossover distortion.

    Just like the Quad 303.

    People get used to a certain sound and think because they paid for it,
    and its heavily advertised, it must be better.

    KEF units to me are very neutral. I like that. I don't get tired of them. Mine cost me less that -u100 when I bought the units and fitted them to
    chip cabinets.




    Can't say I know of anyone selling them in the UK apart from Stirling
    broadcast?..

    **OK.

    'Accuracy' isn't necessarily a problem, and trying to achieve it - at least in
    most domestic settings - is a fool's errand.

    There is frequency response, including resonance, and there is
    distortion, which 'muddies' things up and makes instruments hard to pick
    out in say an orchestra.

    Frequency response is there at all sound levels but distorion tends to
    be less at low volumes.
    The lowest distortion I ever heard at decent power was from profession
    horn drivers. one foot long aluminium cast mid range horn, JBL bullet
    style tweeter.
    Twin 15" bass units and IIRC a pair of 8" lower mid range units.
    Ultimate disco speakers.

    But you can get very good results out of a 3 ways system with a dome mid
    range and tweeter. Distortion comes when you are pushing your small
    upper frequency units too hard, because the are are only two units and
    the crossover frequency is a compromise

    Colouration is simply a fact of life, and in the end people just tune
    most it out in a given environment. Unless there are very peaky
    resonances like what you get with cardboard cones, or an undamped metal
    dome etc.

    I'd suggest the main issue is how good they sound to you, in your listening environment.

    Of course such a measure can easily become coloured by perception, marketing, reviews etc. But hey, if you enjoy the sound . . .


    In the end that is in fact it. People are massively influenced by
    marketing. They don't want to admit they paid -u4000 for two pieces of
    shit or that a home built pair at -u150 is in fact 'better'. I spent
    years designing and testing and listening to audio kit, and learnt how
    to relate what the test equipment said to what I was hearing.

    And I have related my conclusions., Today all amps sound alike, and are essentially so near perfect as makes no difference. and a good CD beats
    vinyl hands down, and is pretty much perfect also. Bad stuff happens in
    the recording studio and in the loudspeakers, but recording studios that
    are now 100% digital are pretty much free of the dreadful recording
    quality that recording engineers with no technical background used to make.

    So the weakest link in the chain is the loudspeakers. You simply pick
    which flaw bothers you least and run with that.

    Good heavens, someone else with a pair of Bailey transmission lines! The
    only thing I did to mine was to add a pair of Coles ST4001 super
    tweeters. They were built by a colleague who got married and moved into
    a terraced house in a village outside Cambridge where he couldn't
    accommodate their size. He sold them to me for -u50 This would be late
    70's) and bought himself a pair of Ram units about the same size as the
    BC1's. The only issue with the TLs was their inability to produce as
    good a sound stage as a two driver speaker. In that respect a pair of
    Denton IIs were much better.
    I built a MOSFET power amp using Ambit (remember them?) modules with
    Hitachi power devices and effectively dual mono. Same mains transformer
    but separate JLH designed regulated supplies feeding the amps. I still
    have it but had to call a halt when it developed a bias fault. The best
    thing was it did 110W into 8R and 220W into 4R both channels driven. The response was within about 0.3dB from <10Hz to 240KHz, the worst phase
    error was about 4deg at 8Hz (yes I had access to some pretty good test
    gear!) I fitted some filters to make it more realistic but it could
    still shake windows at 20ft and only a couple of watts drive. Classical
    organ music was unbelievably real!

    Good heavens, someone else with a pair of Bailey transmission lines!

    **With Radford crossovers. The Radford crossovers utterly transform the
    KEF T-lines (and Concertos). Inductors are air cored (rather than the
    horrible ferrite core types used by KEF) and there is a 24dB/octave
    filter on the HF driver, along with a parallel resonant circuit on the
    mid, to null out the nasty resonance inherent to all the old B110
    drivers (solved by KEF in later production).

    Having lived with both crossovers, I can assure you that the difference
    is far from subtle. Best of all, after replacing the electros with
    higher Voltage types, the speaker could easily deal with my 300+
    Watt/channel Marantz Model 500 amplifier, when used at many parties in
    my 20s.

    **Yes, the wide baffle of the T-lines was a major problem. BTW: You
    don't need a 2 way to obtain good imaging. You just need a speaker where proper attention has been paid to diffraction issues. A pair of old
    Duntech Crown Prince speakers will easily demonstrate that.

    **Yeah. A mate brought his analyser down to my place to check my KEF

    few dB down. Best of all, they never sounded bassy. Largely because they
    were very clean and very flat.

    It was in about 1976, a mate had bought a pair of B&W DM1s in poor condition - the EMI oval woofers had badly frayed cones but the HF1300 and Coles tweeters were fine. He agreed that KEF B200s replace the 10x6 inch EMIs and I do any other work needed.
    So I made mounting templates to suit the new 8 inch round woofers, fitted them and did listening comparisons with my restored Quad ESL57s. The HF1300 tweeter was clearly too prominent so I tamed it by about 4dB with a resistive attenuator but left the Coles alone as it played a subtle role anyhow.
    The mate was delighted with the result and it seems now that I had created a mini Spendor BC1 in advance !!

    known, accurate speaker. The problems are instantly audible.

    That reminds me of when I was developing am audio amplifier for a
    German loudspeaker company, They sent their golden eared boy over
    to blind test two possibles. He unerringly picked the one with
    more crossover distortion 'because it sounded like his Revox'. I
    tested that as well. That too had high levels of low volume
    crossover distortion.

    Just like the Quad 303.

    **I have a couple of Quad 303 amps here. I also possess some SOTA
    test equipment. I will check on your claims about the Quad 303.
    Please advise of the levels and frequencies you tested the Quad 303
    at to arrive at the claims of crossover distortion. I assume it was
    in the region of 20mW and 20kHz or so. That has been my standard of uncovering crossover distortion.

    That is a bit low power wise.
    It will still be in class A at that point.

    Try 10KHz and do a distortion versus (log) power all the way up.
    IIRC it peaks at around 0.5%.
    But it was all 50 years ago..

    The problem with those amps is simply that the Class B operation
    switches off one half of the amp, and it takes a finite time to switch
    it back on, due to parasitic capacitance and other delays. Until it does
    that the internal gain is pretty low.

    Once faster transistors and in particular FETS were in use, that pushed
    the distortion into the ultrasonic band, and clever circuit design
    (which I used, on one amp, but thermal stability was never reliable)
    could keep the 'off' half of the amplifier sufficiently ON to remove the
    effect completely .

    Of course class 'D' amplifiers which were pie in the sky when I was
    designing stuff, don't have any crossover distortion at all. They have
    other problems instead!


    The Sony amplifier I still have from the 1990s uses that technique, with massively integrated output chips so the thermal stability is more than adequate.

    As far as I am concerned it is far moire 'perfect' than my speakers, at
    a fraction of the price of those speakers.


    People get used to a certain sound and think because they paid for
    it, and its heavily advertised, it must be better.

    KEF units to me are very neutral. I like that. I don't get tired
    of them. Mine cost me less that -u100 when I bought the units and
    fitted them to chip cabinets.

    **As were mine. My Bailey T-lines (fitted with Radford crossovers)
    were fabulous speakers back in the day. Very accurate, as measured
    with some primitive test equipment.

    It really depends on what music you listen to. Some people like to hear
    their guts rumble with organ music. T lines do well on that. Other
    people like the thump of the bass guitar and drums. T-lies are 'orrible
    for that. You need a massive concrete bass horn or bass reflex to do
    justice to that. Then again if you are listening to just a few
    instruments, like the average rock or jazz track, intermodulation
    distortion wont affect the subjective effect too much, but if its
    orchestral music with a choir or full violin section. low
    intermodulation distortion will turn it from a 'sound' to 'i can hear
    each voice and each violin' sort of clarity. That's where an ESL scores
    at low volumes. At high volumes use horns.

    Then as far as resonances go, the spoken male voice can sound very
    'woody' or 'boxy'. And mid and upper ranges 'cardboardy' if the units
    have paper cones and the cabinets are badly damped.

    KEF pioneered 'non paper' cones with Bextrene, today you can have
    carbon fibre for bass units and titanium for tweeters and even cheap
    speakers are really pretty good.

    As the other half of my experience was with the exact opposite of hi fi,
    i..e. guitar amplifiers and loudspeakers. I learnt by exposure to
    gross examples, what highly resonant loudspeakers and cabinets,
    especially driven from very high impedances, sounded like, as well as
    high levels of particular forms of distortion. And even the differences between Ceramic, and AlNiCo magnets - and yes there is a difference,
    though why that is I haven't worked out.

    In an electric guitar the loudspeaker and it's cabinet are analogues of
    the soundbox of an acoustic guitar. The last thing you want is to
    accurately reproduce the soulless nature of the strings and pickups.
    Direct injection into the mixing desk is not the way to go, unless you
    can use multiple reverberators to create a synthetic 'sound box' inside
    the effects section of your electronics.

    One thing that theory taught me, is the relationship between frequency response and impulse response. Tap a bass unit in a cabinet, and if its
    a dull 'thunk' it will be a good unit, if you can hear a cardboardy
    sort of 'doink' it will do well for a guitar.

    Then try tapping a violin, or an acoustic guitar.

    **Absolute and complete nonsense. Insanity, in fact.

    Not if coming from an informed view. Informed preferably by live performances and decent hifi systems.

    I think the confusion arises of of the words used in an attempt to
    describe a subjective experience.

    What I understand by 'accuracy' is what is also expressed as 'clarity'
    and is typically the ability to separate individual instruments and
    voices out of a musical piece.

    The best way I can express it is that some loudspeakers turn the 'sound
    of an orchestra' into 'the sound of a lot of separate instruments all
    playing together'
    My theoretical understanding of that is that it almost certainly
    reflects low levels of distortion in the loudspeakers, so the cones and spiders are not reaching the limits of their travel. You wont hear that
    level of distortion on a single instrument, but you will subliminally
    become aware of it when there are a lot of instruments and the
    intermodulation products will produce frequencies that weren't there in
    the original recording. It sounds 'muddy'.

    At low power the electrostatic speaker is one of the best attempts to
    reduce this, but they are fragile and limited. At high power you simply
    cannot do better than horns, because those impedance match the
    compression drivers to the air, so that very small (and hence more
    linear) excursions of the diaphraghms produce much louder sounds. The
    problem with horns is controlling the resonances within them. They are
    clean, but coloured.

    And that brings me to the second part of loudspeaker design. Resonances
    or 'colouration'. If you 'like the sound of those speakers' rather than
    'like the sound of the orchestra,played through those speakers' you have colouration. Resonances - narrow peaks and troughs in the frequency
    response.

    Many people actually like that. They like 'the sound' of their
    *speakers*. I personally don't.

    But I am prepared to trade a little of it for low distortion.


    Even if you have no reference, I don't get too upset by people who buy by label (Bose etc.). It's their money. Internet buying and lack of demonstration
    facilities has made making an informed choice more difficult I suppose. Hats off to Richer Sounds in this regard.

    *shrug*. Ive heard Bose. Its indifferent mid fi crap, but it looks good
    in your minimalist Scandinavian room made out of 'Norwegian wood, isn't
    it good?'

    I'd suggest the main issue is how good they sound to you, in your listening >>> environment.

    **Then that is not necessarily high fidelity. It is something else
    entirely. Accuracy is vital if a claim is made for a product to be high
    fidelity.

    Is hifi 'low distortion'? If so, it sounds OK as a start. I've never known what the term HiFi actually means.

    What you are looking for is accurate frequency response and low
    distortion. Then you hear the music, not the kit.

    Accurate frequency response is hard to achieve in a domestic room,
    especially if its 'modern' and has hard walls and no curtains or carpets.

    The best you can hope for is that you hear the room's resonances, not
    the loudspeaker's.

    But low distortion is achievable in a domestic setting. But unless you understand what it sounds like, you probably wont actually like it. It
    doesn't sound expensive. It isn't something you can hear, its something
    that you *don't hear*.




    Of course such a measure can easily become coloured by perception, marketing,
    reviews etc. But hey, if you enjoy the sound . . .

    **Again: Not necessarily high fidelity. Something like a Quad ESL63,
    suitably arranged in a room, IS capable of high fidelity reproduction.
    The LS3/5A cannot achieve such a thing. Ever.

    The LS3/5A may sound pleasant to an uneducated listener, but it is not
    an accurate loudspeaker.

    Personally, if you've taken the trouble to reach an informed opinion, I don't care.


    Matey is very proud of his electrostatics and very disparaging of his
    KEFs. Ive heard both, and sure at low volumes ESLs are great if you
    don't mind the absence of bass, but I do. And I like to turn stuff up.
    Led Zep are not Led Zep at 60dbA. You cant do that on ESLs., You can get
    a bit closer with KEFs. KEFS are low colouration speakers, but not that
    great at distortion except at rather low power. Nice easy listening for classical, but not for a party, playing rock

    Mine are worth what I paid for them, A couple of hundred tops. I could
    listen to them all day, and did.

    Now awaiting putting back in cabinets


    But for real gut thumping rock, NOTHING beats upper mid and high
    frequency horns and as many big badass bass units as you can screw into
    as large a cabinet as possible and probably some kevlar or carbon fibre
    lower mid range units as well. Its hard to get a horn to go much below
    1.5Khz, and big bass units will crap out at around 500Hz, so there's an
    octave missing in the middle unless you go four way.

    Use separate amps for each driver and electronic crossovers - far easier
    to get 'perfect' crossovers without coils in the way.
    And if you think that's sounding like a typical PA rig from a rock
    concert, yes it, is, just optimised for studio use rather than stadium,

    ESLs are not going to get you 115dB of clean clear disco/rock music on
    the dance floor.

    'Accuracy' isn't necessarily a problem, and trying to achieve it - at least in
    most domestic settings - is a fool's errand.

    There is frequency response, including resonance, and there is
    distortion, which 'muddies' things up and makes instruments hard to pick
    out in say an orchestra.

    Some venues seem to be better at that lack of *muddle* than others i
    reckon!.

    Another debate for another day:!


    Frequency response is there at all sound levels but distorion tends to
    be less at low volumes.
    The lowest distortion I ever heard at decent power was from profession
    horn drivers. one foot long aluminium cast mid range horn, JBL bullet
    style tweeter.
    Twin 15" bass units and IIRC a pair of 8" lower mid range units.
    Ultimate disco speakers.

    But you can get very good results out of a 3 ways system with a dome mid >range and tweeter. Distortion comes when you are pushing your small
    upper frequency units too hard, because the are are only two units and
    the crossover frequency is a compromise

    Colouration is simply a fact of life, and in the end people just tune
    most it out in a given environment. Unless there are very peaky
    resonances like what you get with cardboard cones, or an undamped metal
    dome etc.

    I'd suggest the main issue is how good they sound to you, in your listening >> environment.

    Of course such a measure can easily become coloured by perception, marketing,
    reviews etc. But hey, if you enjoy the sound . . .


    In the end that is in fact it. People are massively influenced by
    marketing. They don't want to admit they paid u4000 for two pieces of
    shit or that a home built pair at u150 is in fact 'better'. I spent
    years designing and testing and listening to audio kit, and learnt how
    to relate what the test equipment said to what I was hearing.

    And I have related my conclusions., Today all amps sound alike, and are >essentially so near perfect as makes no difference. and a good CD beats >vinyl hands down, and is pretty much perfect also. Bad stuff happens in
    the recording studio and in the loudspeakers, but recording studios that
    are now 100% digital are pretty much free of the dreadful recording
    quality that recording engineers with no technical background used to make.

    So the weakest link in the chain is the loudspeakers. You simply pick
    which flaw bothers you least and run with that.

    Absolutely right Phil it seemed that diodes were a bit too variable
    hence the modification that introduced the pot easily done to an earlier version.

    I did once at have chat at an exhibition with Mike Albinson who i think
    had had a few shandies and he was discussing a different circuit
    arrangement to the 303 quite what it was he didn't say and then they
    started dumping currents and that was that. I presume that the didn't
    want to make the 303 "a" or "b" variant anyway the 303 had been in
    production for many years at that point. He did say that if i wanted to
    play around it use a different OP transistor and wind the rail volts up
    i did scribble that info down but it was a long time ago now!..
