The Townshend Seismic Pods retail at £99 each, but AoS members can expect a decent discount. A Seismic Platform costs rather more, of course, but since you have a motor unit bolted firmly to a nice heavy plinth, you don't need a complete platform to isolate the deck from vibrations passing up from the structure of your house - a set of Pods will do that job comprehensively. Remove those structure-borne vibrations and something rather magical happens to the music - after all a pickup cartridge is designed to be a sensitive vibration measurement transducer, so if you can leave it to track solely what's going on in the groove, better music will result. The Pods won't work with a floppy suspended deck, but they will with yours.
