REX 3 DAC

Zero negative feedback for supreme purity and six 6C19 vacuum tubes
REX 3’s analog output stage follows the Balanced Audio Technology purist approach of using zero negative feedback to achieve the desired goals of wide bandwidth and circuit linearity. No buffers or followers are used anywhere in the signal path. REX 3 also features a high-current output stage with a total of six 6C19 vacuum tubes. One pair of 6C19 tubes serves as current sources for the power supply of the elegant, trademarked Unistage design. Just as in BAT’s REX 3 preamplifier, REX 3 DAC also employs amorphous-core second-generation transformers for output coupling. No capacitors are utilized in the signal path.

Proprietary DAC module runs at an ultra-high clock rate, uses custom filters
With REX 3 DAC, BAT wanted to create the most compellingly natural reproduction of the musical source. Ringing from filters that provide a perceived albeit false excitement in playback have no place in REX 3’s design. Instead, the proprietary DAC module runs at an ultra-high clock rate while employing custom filters to reconstruct the analog signal in a way that specifically complements REX 3 DAC’s unique high-current vacuum-tube output stage.
