Background Info
I used to have my all audio equipment stacked side by side on a single marble table. On the insistence of a fellow audiophile Dr. Rawat that I bought a small sleeper wood table for the amp and dug out a 40+ kg lead filled steel frame I build 20 years ago for my ex Linn Sondek (btw, it made no difference to the Lp12).
The assumptions were:
1. Having the amp on its own table will isolate the cd player from any possible amp transformer vibrations.
2. The lead table will negate the need for rollerballs under the CD player as it should be rock stable?
Findings
So playing around I discovered that:
1. Sound is different = seems like a worthwhile experiment. Top end is much improved- the effort seems to have been worthwhile.
2. Placing rollerballs beneath the cd player still makes an improvement. This is the part that has me wondering WHY as the lead table should be ultra stable?
3. It seems to be as if there is some magnetic interaction between the pre and cd player- stacking the 2 units and lifting the pre higher from the cd player seems to make a difference - Weird as the cd has two torroids and the pre has a open c-core transformer. With some experimenting I found an optimum height (4 cm.) for the pre placed above the cd player.
Questions:
1. Any explanation why the rollerballs are still required?
2. Has anyone ever tried to "magnetically" isolating stacked components with steel plates. Would it be worthwhile to have a thick steelplate between the cd and pre?
3. Any other explanation for the above?
Regards
