About the Reference 5

The Reference 5 is a fully differential, real balanced-output R-2R DAC built around four Burr-Brown PCM1704U-K multi-bit chips, with two chips per channel for front-to-back differential signal processing. It provides three digital inputs (Toslink optical, coaxial RCA, and USB, all up to 24-bit/96kHz due to PCM1704 limitations) and three analog outputs: single-ended RCA, balanced XLR, and ACSS current-mode output using Audio-GD's discrete, zero-feedback output stage. The unit incorporates Audio-GD's proprietary DSP-1 digital filter processor based on an Altera Cyclone FPGA, a two-channel interpolation filter and data processor that reclocks data and master clock for near-jitter-free operation, contributing to its highly transparent, detailed presentation and expansive soundstage. Operating in pure class A and using fully discrete, DC-coupled analog stages (no op-amps, no coupling capacitors), the Reference 5 is widely regarded as a substantial upgrade over typical integrated CD-player DAC sections in its price class.
