I recently bought a Playback MPS-5, second hand, which also has an esoteric mech. It sounds great but the mech is noisy, if I put it on pause I can hear it from my listening position.
when playing it makes a whirring sound which seems similar to what other have heard and can be heard above the music at low level, from a few feet away.
