Turntable Isolation


I have quad 22 l-2 speakers, NAD c-162 preamp, pair of Adcom gfa-555 amps, Cambridge Azur 640c cd player, Rega p3-24 turntable with TTSU and Herbie's mat.

Listen to all types of music, from classical to Sinatra to Miles Davis to early rock to Wilco to Arcade Fire, etc.

I've been looking at isolation solutions for my Rega (Gingko, etc) and decided to make something myself. I bought a piece of hardwood, cut it into two 19" x 16" pieces, drilled 5 dowel holes in the corners and the middle of one piece, placed Dunlop Sport (2 dot) squash balls in the dowel holes, placed the other piece of hardwood on top. Then, placed my Timbernation 2" thick maple turntable platform with spikes on top of the second piece of hardwood, then the Rega. Seems to work ok. My question is; how compressed should the balls be in order to get the best isolation for this "solution"?

Thanks Schipo. Just weighed the whole thing and it comes to 23 lbs. I need to take the center ball out and then add 17 lbs. Holy Moly! Have you experimented with this type of thing?
Hi Macdad:
I'll be happy to give the vibrapods a try; they are only $6 bucks each. The feet on the P3-24 are rubber with screws and can be easily removed, I think. So, let me make sure I've got this right: Your turntable has threaded brass cones, cones sit on the floor savers, floorsavers on the Vibrapods, Vibrapods sit on the butcher block, and the block sits on siicon gell pads?

What a great set-up! Then, the turntable is leveled with the brass cones. You stated that the floorsavers sit on top on the Vibrapods, they don't fit down inside them, right?

I've got the Timbernation block already, so your set-up will only cost me $30-$40. I'll give it a try, even though the squash ball rig seems to have opened up the soundstage and surface noise is lower.

The first response I got from Schipo is one I respect, but 10 lbs. per squash ball seems like a lot. I took one of the balls and put a 10 lb. weight on it; squished it down to nearly flat. It has got to be less that 10 lbs. per ball, doesn't it?
I've got a 10' x 16' room, speakers at the end of the room, 2 feet from back wall, 8 feet apart (like Quad people recommend). Turntable is on a rack along the side wall, about half-way back. It is not ideal, but I don't have a way to move it to another room, which I know would be best, so I'm trying to isolate as best I can. I could put the rack between the speakers or even move it farther back on the wall away from the speakers. What do you think?
Ok, Johnnyb, I'm ordering the vibrapods today. And, I'm going out to get a few floorsavers and a couple of gels. I'll let you know how it works out.
