Ive been mucking about with my speaker positioning trying to improve my imaging when all i really want to do is to listen to Cat Powers sexy tones , and i noticed my speakers wobbling like mad when cueing up. This is obviously connected to rumble on the LP but ive only just noticed it. Is this an occupational hazard of playing vinyl? Should i just ignore it and pretend it isnt there ?? Or is there some tricks of the trade which can improve the problem.
