    So why if we had a number of components using IKEA tables as their foundation and then move them to a Stillpoints rack that they sound much better?

    How much better? So much so that if they were behind a curtain and you couldn't see what they were stood on, you would be confident that you could pick out the stillpoint every time?


    When I was still doing tweaks like that I always used that as my benchmark. I think it sounds better with the tweak, but would I be confident about spotting the improvement blind? If the answer was no, and there was no established explanation for there being an improvement, then I'd dismiss what I was hearing as a psychological effect.

    I used to think - or just assumed - that solid state electronics were totally immune to any effects from vibration but many years ago I designed an integrated amp with an mc phonostage and was surprised to discover that it was to some extent microphonic. With the mc input selected and the volume control maxed out it would "ping" through the speakers when the case was tapped. Of course, in practice it would have been impossible to use with the volume control on full whack but it did show that something inside the amp was sensitive to vibration.
    Unfortunately I never had time to identify the offending component(s) but I suspect it was capacitors and/or transistors with "twangy" legs.

    However minimal, even with S/S the materials inside are not homogenous, and differing densities will result in differing reactions to applied vibration, this producing differential movements.

    God knows how many dB down it all is though.

    The Wave Kinetics stuff is interesting but itís all conjecture and theory, there isnít any attempt at actual scientific justification for any of the, many, claims made.

    You're being very kind I think. It's actually a shockingly blatant load of old cobblers from start to finish.

    One of the popular theories about tweaks, is that while one tweak may not make a noticeable improvement, they may add up to something noticeable all added together. While there seems to be some logic in this idea, I find it all very tedious.

    I do wonder whether the exhibitors of crap-sounding systems realise they sound crap, or if they actually like the sound, even if most visitors to the room listen for a few seconds before fleeing from the godawful racket. Their choice of music is also invariably dodgy, so you get crap music reproduced in a crap way.
