Isolation for my Rega 3

Hate to bring the neurosis of the "Isolation vs Absorption" discussion over here, but to respond to my own post above: After an extended period of using cones, I've gone back to the original cup-shaped, rubber feet of my old Planar 3 (still with the BrightStar sandbox, for the time being). I'm giving up some resolution and air, but coherence and ease of the overall presentation is better this way. I had assumed that I didn't want a compliant foot between the plinth and the sandbox -- so much for that assumption.

GO TO YOUR LOCAL DRUG STORE & BUY A PUMICE STONE, CUT IT INTO 3 OR 4 PIECES AND PUT IT UNDER THE FEET OF THE TURTABLE!! WAALLAA.... ONLY $3 AND IT WORKS.I USED IT UNDER MY EUROKIT THAT HAS NO SUSPENTION..

If I could, I would wall mount, like David. My Planar 3 is on my equipment rack, sitting on a BrightStar Big Rock. That does a good job of reducing grain. I looked for a cone-foot to couple the plinth to the Big Rock that would make the TT sound a little faster (perhaps some pace lost due to the Big Rock?). The brass, heavy-weight, triple-points from Mapleshade are doing a nice job of that plus cleaning and freeing up the sound in other regards. The regular Mapleshade cones made improvements as well; the big guys are better. Between the Big Rock and equip. rack shelf, I have VibraPods to handle low-freq., hardwood floor-borne vibrations.

I'm pleased, but with all this, I feel like I've taken the merits of my equipment rack out of the picture. The rack is very light and of welded steel. So, in the spirit of simplicity, and also that of not leaving well enough alone, I am going to test a different approach and just put the TT on a high-quality, lightweight shelf that has a vibration control approach more akin to that of my rack. But I should emphasize that my current treatments have really helped.

This may cost too much for your budget, but items with rotaional vibrations like turntables and CD players improve
very much with bearing isolation devices like Aurios MIB or
Symposium Rollerblocks, cost $300 retail.

You need a light but rigid base for the Rega.They dont like to sit on a heavy base. I have a wall mounted shelf with a Bright Star Audio Big Rock #4 under my P-25.It works great.I had acoustic feedback until I installed the shelf and bought a rock.I wouldnt use anything heavier than a #4 under the table.Its the perfect size rock for Regas.I got mine at Audio Advisor for $90
