Oh, the Airpax motors aren't hum-field free and decks made after 2000 or so, used adhesive rings to hold the motor in place on the plinth laminate (sounds awful, doesn't it) with no metallic content above (laminate, then glass platter. I can scan HiFi Choice tests with some objective data if required.That's just magnetic pickup from the amp's transformer field leakage, as any dealer should have known. It's nothing to do with the Rega's motor. Decks with steel below, like the LP12's subchassis back then, probably provided some incidental magnetic shielding. I suppose the Rega cartridges might have been relatively light on magnetic shielding too - I've never used one. I always considered putting the arm, cartridge or cables close to a large transformer to be asking for trouble, which is probably why I never ran into this 'problem.'
I'm making a perfect case for an SL100C aren't I?
I still think the AT LP5X might be worth a good looking at, as apparently, the 120XUSB is a plastic shell with steel? plates to make it appear heavy.....
