And the classic most-raved answer for your kind of table--- assuming you mean a suspended-sub-chassis Sondek style like the lp-12, td150, etc, etc-- would appear to be the Mana Acoustics style of steel-bound glass-shelf supports.Yes, you'll get a myriad of opinions, but over many years this seems to be the most-liked single choice of critics, Linnies and others with that style of deck.
Combine that technical style of shelf design with the isolation of wall-mount placement, and you may have the best of all worlds....

Here's my current mental gymnastics dilemma, and perhaps some of you could offer an opinion on it. I'm just getting back into listening to vinyl, and I was going to mount my table on a massive (chimney flue & concrete pavers) DIY stand I saw on another site. I always thought low and massive was the way to go.After reading many posts on The Vinyl Asylum I changed my mind. My house is built on a concrete slab, but there's plywood over that for the rug to be laid on. I figured the plywood would be a potential source of vibration transmission to the turntable stand. Also, I've got a Boxer (a dog, not a pugilist) running around the house and didn't want my cartridge at cold nose level.
One wall of my listening room is an outside (load bearing) wall, so I decided to wall mount instead. I ordered a Target wall shelf right around the time I ordered a new cartridge, figuring I'd eventually go the Target/Greater Ranges Neuance shelf route that many here have had success with.
Now I'm not so sure again (hence the mental gymnastics). Now that the Dennon 103R is mounted in the Rega 900 I'm getting bass like I've never had before, and loving it. Currently the Xerxes X is sitting in a homemade sand box, atop a RoomTunes clamp rack, which I always thought was "too tall" to be a good candidate for a table.
While music was playing the other night I got up and felt the wall where I planned on mounting the Target shelf. The drywall was vibrating like the skin on Ringo's snare drum. It didn't matter where I felt along the wall, the whole thing was moving. The same light fingered touch on the top of the Clamp Rack (even prior to the sandbox) produced NO feeling of vibration.
So now the question becomes, do I leave well enough alone, and leave the table where it is, or screw 10,000 drywall screws into the studs, then patch and paint the wall prior to mounting the Target? Would that even help? I'm humbly asking the experts about this one.
...you have a solid base (floor), which is quite a desirable thing for many. why mess with that?drywall can vibrate like a skin, as you are experiencing. in my opinion, a wall-mounted shelf in that situation needs further isolation to be effective. witness: the finite-elemente wall-mounted shelves.
the vibration induced from the wall are substantially lower for many people who have suspended wooden floors (but maybe not for your situation).
the finite system incorporates:
1) a secure bracket that goes on the wall;
2) a frame that has some isolation from the bracket;
3) a shelf that sits on top of the frame, and employs some isolation/resonance control as well.such a solution could offer an improvement for you, but it is also possible that a basic wall-mount may just shift your problem to that of dealing with vibrations from the wall/drywall.
unless you are going to take a finite-type (or other non-brand-specific) approach, then it seems like sticking with what you've got will save you time and money.
Thanks for both your feedback and your take on things. I'm inclined to agree with you about "sticking with what you've got", since it seems to be working. At least from an anti-vibration stance.On the other hand, I already have the Target wall shelf (Mana is out of business) and I'm not out anything but time in trying it. Since Ken Lyon offers a trial period with his Neuance I won't take a loss there if the wall mount doesn't work for me. I've also considered "constrained layer damping" mounting of the Target to the wall, using plywood, Gater board foam, and aluminum. This is something else to ask Ken about.
I noticed we both commented on the mass loading article O'Malley linked to. In that article it's mentioned that mass can sometimes choke the life out of a component. That's why I originally changed my mind from a massive stand to the Neuance/Mana method. I'm definitely (back) in this hobby for the music, not the "I can hear the drummer's stool squeaking, hung in a deeper, blacker background" hi-fi show.
