Turntable Isolation

Cool project.

What kind of feet are on the P3/24? I have a Technics SL1210 with aftermarket threaded brass cones. I just did an experiment using the cones on top of metal floorsavers that are wide enough to span the top of Vibrapods, then placed on Vibrapods (which are platformed on top of a butcher block cutting board supported by silicon gel pads). The spikes-to-Vibrapod addition dropped the noise floor dramatically and brought forth a new level of dynamics. Surface noise dropped noticeably and microdynamics have come alive.

Are you willing to experiment with Vibrapods instead of squash balls? Since they make 5 models with different weight ratings, it would be easy to pick the Vibrapods that deflect the correct amount for a given load.

Also, the Vibrapod instructions say to never place one dead center; I wonder if that would apply to other absorptive modules such as the squash balls?

Another alternative for the squishy middle of a heavy wood sandwich: silicon gel wrist rests for computer keyboards available at your local OfficeMax, Office Depot, Staples, etc. I use two 19" long gel wrist pads under my cutting board.

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?

Where is your table in relation to your speakers? I am surprised I don't hear more about people placing their table in a separate room or equipment closet. At the very least one should look for a null in standing waves. All equipment remedies will help still further but the best location should be the starting place.

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?
