Where is Your Turntable?

Due to lack of space I have Lovan 3 point stands with .75" marble shelves with the turntable sitting on top with an extra 1.25" granite slab separated with rubber buttons. All of it sitting between speakers. I haven't had problems with walking around or vibrations from speakers but the granite does have a "ring" when you tap it. I am considering a maple platform and maybe some Ganymede feet beneath it. Would the lateral movement that is possible with bearing type iso have negative effects on turntables. Would the arm bounce back and forth in the groove?

Well, you can tell where mine is by my system pictures, but for those who don't wish to look it is behind and almost centered between the speakers on top of a DIY stand. I toyed with placing everything opposite the speakers (and I still may), but the wall behind the speakers is very accessible so that's where the dedicated circuits went for the analog and digital components. My table may be a bit high off the floor but since everything is on a concrete basement foundation I didn't worry about it.

Like those absorbers, 4yanx! I have four, 3x4, one 15"x90", and a boatload of Jon R's bass traps. Most of those are the 12" diameter, but I do have one 16 incher that tames the bass in a particularly troubling corner behind the speakers.

Mthieme, RE your ringing granite shelf: The rubber buttons are making the ringing worse. A little tip: when you put a heavy material like glass or granite on a another surface or shelf, place a sheet of thin 1/16" foam between them (you can find it anywhere they sell packing supplies.) It mates the two surfaces together uniformly and damps out any vibration between them.

Glass and granite do have a high frequency sonic signature and they need to be uniformly damped/mated to a substrate like wood (or even another slab of granite!) which is accomplished easily with a very thin sheet of foam. It would be even better to spread a layer of contact cement and laminate the two surfaces together, but that gets a little messy as a DIY project, and foam gets you 80% there.

Thanks Neil,I think you are right, it probably does resonate because of the rubber suspension. The granite seems to weigh about 80 lbs, and if it was completely coupled to the next layer I bet it would be quite dead. I will try your fix first since I already own the granite. I've read several threads lately that seem to imply that platforms with some "spring" like wood absorb,drain vibes better than high mass materials like granite. Timbernation.com has some beatiful racks that caught my eye however.

About 1 foot behind and inside of the left speaker. Not ideal in anyone's book, but it's all the room allows.

We had to make a functional, decent looking living room, leave the fireplace exposed, include the audio system AND a 43" widescreen. All this in a 13 x 17 space. Now that was a challenge.

It took me two months of shuffling furniture and equipment around (on my computer screen, fortunately) before I got a layout that worked... more or less. There isn't a spare cubic inch anywhere, yet it doesn't feel crowded. (Of course I'm pretty skinny!) Even the cats have room, and the sound in the sweet spot is actually quite decent.
