Here are some details from the Beresford website:
The Beresford TC-7510 is an uncomplicated Digital to Analogue Converter with design features offering the ideal solution for the modern day high technology home hi-fi or multi-media environment.
Most digital to analogue converters are aimed at the CD and DVD audiophiles. The TC-7510 has however been designed for a broader range ofapplication and has been further optimized for accurate PC and wireless digital audio reproduction. That includes wireless servers such as the SB3, AirportExpress, DAB radio, and satellite audio.
The TC-7510 is a 4 digital inputs audio DAC with 24bit/96KHz digital input capability. It reclocks and resamples incoming digital data usingits own inbuilt jitter free clock in order to negate jitter in the original signal.
The actual Digital to Analog conversion process takes place at 352.8KHz for a 16 bit/44.1KHz CD audio signal, and 384KHz for DVD audio.This higher frequency sampling rate accounts for a large part for the detailed resolution and separation of singers and instruments in a recording.
In addition, it has a headphone amplifier and two line outputs. The multiple input and output options enhance the practical uses and increases the versatility of the TC-7510.
