Hmm, maybe maybe not ... I installed one of the new Clearaudio decks with the opposing magnet bearings last week ... It sounded superb ... Those magnets are nowhere near as strong as you would need to float a heavy piece of kit as they are only holding up the platter and don't actually float it anyway, just take a large part of the pressure off ... on the other hand they come within centimetres of the cartridge at the end  of side to no apparent ill effect.
