Bel Canto Design eOne DAC-3 Preamplifier with Ultra-Clock Technology

The Dac3 fulfills the original promise of digital music reproduction. It surpasses previous expectations of digital music quality. This performance results from a unique combination of design techniques, new technologies and the superb stability of our new Ultra-Clock: making the Dac3 a one of a kind product in the market.
The surpassing musical performance rests on the solid foundation of the Ultra-Clock™, a clock with performance found previously only from separate Master Clock products. The Ultra-Clock™ provides jitter performance 50x better than other clocks. Specifications of 1 picoseconds RMS and frequency accuracy of 0.0001% define new benchmarks in clock stability. This Ultra-Clock™ allows the Dac3 to reproduce music with new levels dynamic expression and accuracy of timbre. Your music communicates as never before, recalling the best of analog music reproduction, without the limitations of either analog or other digital technologies. The Ultra-Clock™ works in concert with every detail of the Dac3’s design to achieve a new level of musical realism:
1. Digital input isolation and switching 2. Multi-Stage Jitter rejection 3. Linear Phase Digital filters 4. Low noise Digital to Analog conversion 5. Class A Analog output stage Current to Voltage conversion and analog filtering 6. Class A Analog output buffer to drive the preamplifier or amplifier stage
The Dac3 has been optimized to provide the highest level of performance for all of these critical functions. It can provide digital preamplifier as well as D/A conversion and bridge from traditional CD or DVD player sources and from the isolated USB input for computer music playback sources. The Dac3 has 5 digital inputs:
1. AES with transformer coupled input for high common-mode noise rejection in professional environments. 2. Transformer isolated SPDIF RCA input. 3. Transformer Isolated SPDIF BNC input. 4. Wide bandwidth TOSLINK input for versatile interface to consumer grade equipment. 5. USB input with galvanic isolation for optimized connection to a computer based music source with ground and power isolation between the computer platform and the audio system.
