Hi Blbloom; I have thought of this, but never tried it. I suppose the question is: are the hockey pucks resonant or non-resonant (I would expect non-reasonant). Some Levinson components have the AC receptacle on the underside of the chassis (eg, 360S DAC), so power cords must have a right angle bend, and the Syn. Res. that I use projects down so far that the DACs feet don't touch the shelf. So to use the cord, I seriously considered hockey pucks but had no immediate source. I ended up using sandstone coffee table coasters (actual slices of rock) with cork on the bottom-- they're about 3/8" thick and 4" in diameter. They seem to work great. Let us know how the hockey pucks work! Thanks. Craig.
