Described as a 'string-drive' by Acoustic Solid, its 60mm-thick heavy alloy platter is in fact driven via a continuous silicone rubber belt. Unlike a thread drive, this circular-section belt is extremely flexible, allowing the separate, synchronous motor to be parked in a wide variety of positions, or at least at over a wide range, from the diagonal cutaway in its plywood plinth [see picture, left]. While the platter spins-up over a respectable 5secs, the precise motor position and belt tension does have an impact on wow and flutter, the best result showing a clear 4Hz 'split' in the signal peak of 0.05% [see Graph 1, below]. Rumble is perfectly acceptable at -68.5dB, although not state-of-the-art, and there's an improvement of some 0.6dB with the record weight in place (all measurements were made with the supplied 5mm acrylic layer over the leather mat).
