Tried everything except a wall mount and 300-500 lb granite platform (couldn't make the wall mount work in my room & didn't want to gamble on the platform). Moved the table in the end. If you have suspended wood floors, low frequency feedback can be a bugger.
How to properly isolate a turntable?
When I hook up my turntable and drop the needle I get some very bad cone movement , this happens also when there is a lot of bass and drums. I would like to know how to properly isolate a turntable to avoid rumble. How can this be done without moving the turntable away from the speakers? Any suggestions?
