The original problem was that, after having read on this net about this subject, I ran out and bought a record clamp. The trouble is that, since I have a manual turntable, the cartridge can bump into the clamp at the end of the record, unless I jump up, run across the room, lift the cover, and hit the cuing. So I called to ask about a low-profile record clamp that would avoid this. Well, the salesman told me that clamps and damps are out. Today's high-end turntables are made of NON-DAMPING materials, like acrylic. What say you all to that, eh?? He went on to explain that acrylic has the same resonant frequency as a record, a statement which shows an admirable ignorance of simple physics. Damping takes out the harshness, but music is sometimes harsh, blah, blah, and the logic started to fade a little. So waddaya say, folks? Do we use rubber mats and C-clamps like we used to, or do we go to glass? By the way, who knows of a record clamp with a low profile and which will not bump into my tonearm?
