Mass and vibration cancelling on top of CD player?

Why does it make a difference and what should be expected?"

If I knew that, I'd make my own like of super expensive products, and you guys would have yet one more mystery brand that everyone complains about.

My best guess is that the combo of cones and the book dampens the CD player from vibration. Keep in mind, though, I said mass market. It worked on a cheap Pioneer Elite universal player that weighed about 2 lbs. The same tweek has no effect on my Wadia. It already comes with cones from the factory and weighes a little over 50 lbs. Its one of those things that youy just have to try. Its not expensive and you may get lucky and get something out of it.

I also use VPI bricks. One on the transport and one one the DAC. I am not sure about it's effect on the transport which is well built and heavy, but I am pretty sure that it quells vibrations in the thinner casework of the DAC.

I've found at my modest listening levels my Lexicon RT 20(electrically well isolated and conditioned) does not vibrate from the bookshelf speakers I am using( and there is 16 feet from the speakers to my solid hi fi stand (wood); but, it does vibrate from its own turntable, more with some discs than others.I will try your suggestion tonight. PS. I once heard Wadia (581 I think)played through very nice horn loudspeakers in a very large (18'w x ~35' long by ~ 17 feet high) nicely treated (not overdamped) room. I was very impressed by the reproduction of classical music from the 60's ,on CDs, that I had previously only heard on vinyl. I was very engaged, satisfied and impressed with the musicality,detail and dimension of the sound. At about $6000 it was and still is out of my price range-so I envy you-well not exactly envy- but I'd probably trade you players in a flash!

I'm using 2 Fat Boys from Eden Sound on my ARC and I also found a difference in the sound. I did it principaly to even the weight distribution as it sits atop Bright Star Big Rock/Air Mass combo but found it also improved my sound.

The VPI brick is an electromagnetic device. Roxy54, I have a sneaking suspicion Rja was pulling your leg.
