Tim de Paravicini began contemplating a radical new design for a turntable several decades ago, but the advent of digital audio put the project on hold. Now, with interest in analog not only continuing but growing, he has finalized his design and introduced the Disc Master turntable. While many turntables have appeared on the market in recent years, few offer as many novel features as the Disc Master, but this is not novelty for its own sake. The Disc Master represents a new standard for LP playback.
Most striking is the no-contact drive system. The need to transfer power to the platter of a turntable has always been problematic, as any system with the capacity to transfer power can, by the same means, transfer vibration. Flexible rubber belts have proved a satisfactory solution, but suffer problems of slippage—hence, uncertain speed—and they pull the platter sideways, which can result in stability problems. Tim de Paravicini has arrived at an ingenious solution that solves these problems. A low-noise motor, controlled by a carefully optimized servo loop, drives a subplatter via a geared belt that ensures absolute speed control. The sub-platter drives the platter via an arrangement of opposing magnets. This method not only eliminates slippage, but allows enough compliance to filter out any remaining vibration from the motor and belt, while applying a fully symmetric driving force.
Bearings are another problem for a turntable designer, one that Tim de Paravicini has solved by the use of Swiss-made, precision angular contact bearings, which are as quiet as the more common point-contact types, but wear much more slowly, so that their 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 aluminum chassis. Adjustable, damped feet support the assembly. Three speeds—33, 45, and 78rpm—are offered, with a continuous speed control for 78 to accommodate discs cut at non-standard speeds.
All common tonearms can be mounted and adjusted with ease. The Disc Master is also available with a special EAR version of the Helius Omega tonearm. The Omega arm is as radical a rethinking of tonearm design as the Disc Master is a reconsideration of turntable design, and the two work superbly together. Positive Feedback Online e.a.r. Disk Master turntable By Robert H. Levi, October 2009
"...The E.A.R. Disk Master turntable is all you've heard about and more. It plays your favorite LP's with significantly less distortion and noise than any other table in its price range or substantially more."The Absolute Sound Review of EAR Disc Master
"...This design represents a breakthrough in turntables, and as such is probably the forerunner of a revolution in LP reproduction. What this means in terms of sound is that, for the first time, you don’t hear the LP, an experience akin to riding in a car whose wheels do not touch the road. Make no mistake . . . this is the future!"
