Suspended vs. Non Suspended TT on Concrete Floor

Am considering purchasing a Clearaudio Reference or Master Reference table that would sit on a large Polycrystal amp stand. The stand will sit directly on a carpeted concrete slab basement floor. The speakers, which are about even w/ the turntable are about 9ft. apart (4.5 from the table). Would the high mass/weight/coned design of the Clearaudio tables need, or benefit significantly from, further isolation like a Vibraplane or other like device. Your advice is appreciated.

in my view, you would degrade the sonics of either of the clearauido tables with the use of an isolation device like the vibraplane. the suspensionless design should work perfectly on a rigid/high mass stand placed directly on concrete through a good set of spikes. it would be better were the tt farther from your speakers but we all must compromise. BTW, there will shortly be offered a new clearaudio model between the reference and master reference. it will have 3 motors but be only 2 "layers" high, rather than the 3 of the master reference. -cfb

The best set up I've heard is highly WAF unfriendly. Sounds like you may be setting up in a basement; if you can get away with it pour a 4' high concrete pillar directly coupled to the concrete floor. The large Sonotubes and half a dozen bags of premixed cement will do the trick. Isolation at it's best? You betcha! A little extreme, maybe, but most of us aren't entirely normal.

Jeff, what is a sonotube? I have the same situation and may try that approach.
