The current resurgence of the LP has a new champion! Amid the many new turntables gracing the market, few if any offer as many novel features as EAR Master Disk. But this is not novelty for the sake of it, and we are proud to announce a new raising of standards. Most striking perhaps is the all-new ?no contact? drive system. The need to transfer power to the platter of a turntable has always been a source of trouble, as any system with the capacity to transfer power can by the very same means transfer vibration too. Flexible rubber belts have proved a fairly satisfactory solution, but suffer problems of slip and hence slightly uncertain speed, and they also pull the platter sideways which can result in stability problems.  Now Tim de Paravicini, the renowned designer of EAR amplifiers, has come up with an ingenious solution that solves all these problems. A low-noise motor, controlled by a carefully optimised servo loop, drives a sub-platter via a toothed belt. This immediately eliminates slip and ensures that speed is absolutely controlled. The sub-platter drives the main platter via a clever arrangement of opposing magnets. Again, this cannot slip, but it allows just enough compliance to filter out any remaining vibration from the motor and belt, whilst applying a fully symmetric driving force. Bearings are another problem for any turntable designer. We have solved this by using precision Swiss angular contact bearings which are at least as quiet as the more common ?point contact? types but wear much more slowly, so that performance after years of use will be as good as on initial purchase. The platter is made of an ultra-low resonance composite of resin and inorganic filler, accurately machined and supported on an instrument-grade aluminium chassis. Adjustable damped feet support the assembly and all the usual arm types can be mounted and adjusted with ease. For the ultimate in flexibility all three speeds - 33, 45
and 78 - are offered, with a fine adjustment control for 78 to accommodate discs cut at non-standard speeds. Truly a turntable for the connoisseur!
