I have my TT suspended through the ceiling by four cables into eye hook lag bolts threaded through a 1/2 inch glass shelf with nuts on the underside for leveling. Eliminates all vibration except for what travels through the atmosphere of the listening room. Cables are secured in the attic to conduit pipe that spans the roof trusses and is held in place with conduit brackets. I can't think of a better way to isolate a TT other than having it in another room far from the listening room.
Isolation stands: snakeoil?
I understand that turntables are uniquely effected by vibrations due thier sensitivity to that kind of energy. But here’s the thing: most turntables, especially decent ones, have vibration control measures built into them via footers and various construction techniques. So, the question is: are turntable stands / shelves with isolation features actually beneficial or are they just horrendously overpriced accessories for audiophiles?
