The best turntable islolaters are the doors between the speaker room and the electronics room. My ex-laundry room has all but the speakers. Of course, guests are not as impressed with the array of electronics, but that was never my goal. Another big benefit of this is the dryer's 10 guage wiring that now comes from a 30 amp 110 volt dedicated breaker.
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?
