>>I admit your theory sounds plausible. I have not attempted to use just an object of some weight on my amp's transformers. I also don't own any of the previously mentioned devices to compare with a heavy object of given weight. I wonder did your friend hear a difference immediately when he put the Shakti stone on the amps, or did he notice after some time or after removing them?<<He didn't say, I only know that he was evaluating them for possible consideration of including the item in his dealership, and they found it no better than regular weight. I saw the large wooden Shakti candleabras in the showroom, but never listened to them myself. Nor have I listened to any VPI magic bricks. I have in the past however, tested dead weight (like regular stone bricks) on top of my cd player or amp. I didn't like the effect of that, it made the music sound "squashed", just like the visual effect. That is -not- meant as an evaluation of VPI's product or any other, and I did not place mine on the transformer either. I know the VPI product is alleged to have an effect on EMI, which a brick wouldn't, and I don't know if the resonance tuning effect of the weight is even intentional with the magic bricks.
>>Everyone I know personally who has used any of these devices only noticed an effect after some decent amount of time passed or after removing them (IMHO that's the best way. Leave them on for about 20mins and just keep listening. Then while a song is still playing have someone remove the device from the transformer --- BAM! That's when you'll hear what it was doing, after it's gone!) Just like the Joni Mitchell song says, don't it always seem to go, you don't know what you had till it's gone...<<
Yup, she was right. I know the PWB stuff -really- has that kind of effect, more than anything else I've ever tried. That is, removing it can for many, have a more noticeable influence on the sound than the initial change of installing it.

Hello Again Posy,I found your statement about testing dead weight like a regular stone brick on top of an audio component to be quite interesting. I never quite understood how an electronic chassis could be over-damped. One would think that the deader i.e., less resonant an audio component's chassis is, the less it could possible editorlize the music being reproduced.
So it would seem logical that the more weigh added (provided it didn't damage the chassis in any way) the less resonant the audio component would be, and the less it would effect the music. Yet I've heard others say exactly what you did about the music's sound being "squashed", as if the dynamics have been removed and the soundstage collapsed, when adding what I believe must be too much weight to a audio component's chassis. Personally I cannot understand why this would occur and I'd be very interested if anyone could offer any intelligent reasons for why it does.

I don't think you're killing resonances here, so much as you're tuning them. The resonances are still there, but of a different frequency. Tuning resonances can change the sound a million different ways. (I can hear the sound change from moving a dime on a loudspeaker by a mm or so, so consider that as one of a million different ways). Point being, "changing" the sound is easy. Changing it so that it's entirely an improvement is much, much harder. Whether it's a brick or a dime, I've not been able to do that with dead weight on top of my gear (unless the device was capable of producing good sound in itself, in which case, I wouldn't be referring to it as "dead weight").
$10,000 says you couldn't hear the effect of moving a coin on top of a speaker unless it was moved to a spot where the coin rattled (from a spot where it had not rattled).I believe this extraordinary self-serving boast about your hearing ability is pure fiction.
