SONY TTS-8000 (Vintage)

摘要

As you can see from the pictures in this review, our sample of the TTS-8000 direct-drive unit was mounted into a very heavy chassis with adjustable feet.The 320mm diecast aluminium alloy platter is also directly damped with a thick, rubber mat that helped yield a low -68.8dB through-groove rumble. It's possible the figure could be improved slightly by recourse to a record clamp, firmly mating the LP to the mat, but one was not supplied with the original deck. It's not uncommon for high-torque motors to generate their own noise/cogging components that pass up through the spindle in direct-drive decks, but Sony's brushless/slotless servo-controlled DC motor is remarkable free of such artfacts, offering a through bearing' rumble of just -72.0dB (DIN-B wtd). There is some evidence of noise from 58Hz-73Hz on the unweighted spectrum [black infill, Graph 2 below] but all such 'rumble' is well below the level of the background vinyl 'roar' [blue infill, Graph 2].
