Hey Charles!
It's Bill. I could just call you, but that would be too simple!
Need advice... LP12 - Isolate or Couple??? That is the question! Cones/Spikes/Footers vs. Sand Boxes, Air Bladders, Sorbothane, Raquetballs or anything else "squishy"? Or... if you have a platform between the TT and the shelf on your audio rack, maybe a combination of the two???
Right now, I have a Sound Organization TT stand (spikes down to disks on the top of my Oak cabinet) with the MDF (?) insert board that the Sound Organization stands come with. That insert board rests upon the upwards facing pinpoints that run along the inside rails of the stand, for a second coupling point. I then have 4 metal cones (manufacturer?) under the frame of the LP12 to raise it off it's stock footers.
Can't decide on what's best or where to start!?
