Rollerblocks under turntable ?

Mike, before using a second platter as rim drive I used Rollerblocks with belt drive with substantial improvement over the VPI air ball suspention.
Dan_ed, I don't hear any lost in LF impact, bass is tighter and well organised.
But as you suggested I will give Stillpoints a try, anyway if not better I can use them under my amp. I have no intention to sell the VPI because I compared it with top other suspended and non suspended turntables and this fully tweaked TT sounds better to me . The rollerblocks are also useful as side buffers when a rim drive is used for speed stabilizing and vibration control.
I must say that IMHO it is a cost effective upgrade that can be done on many brands of turntables and I have compared a few in my system.

Stringreen: can you give us more info about your PonTunes vibration control device ? Some pics and how it works ? Thanks.

I've used most of the ones listed above, Rollerblocks, Mapleshade, Black Diamond, Finite, ect.. Some worked better than others, Some were just to unstable. Go with the Grand Prix Monaco Rack & never look back, awesome results. SRA & HRS are also very high quality products.
I got the best results with the Grand Prix.

I tried Roller Blocks but found Stillpoints to be superior under my TT.If you do go the Stillpoint route be sure to get the risers for the base and mini inverted risers for between the TT and the Stillpoint.
Good luck

I agree with Goldeneragauy, I have experimented with the supplied Millenium feet, Rollerblock juniors and Stillpoints, with and without risers, under my TW Accustic Raven one. The Stillpoints were clearly superior used on my wall shelf. I did'nt find the risers added significantly.
