Balanced Audio Technology REX 3 DAC

Description

The BAT third-generation SuperPak is now standard

REX 3 DAC now incorporates BAT’s third-generation SuperPak as standard. For the first time, the BAT SuperPak features hybrid construction that incorporates two capacitors built and potted into each individual shell. An additional silver-in-oil capacitor—arguably the finest-quality capacitor offered at any price—is used as part of the Gen 3’s construction. The two capacitors are then assembled into a new low-resonance shell. The REX 3 DAC SuperPak assembly features the largest SupoerPak ever offered by BAT in a preamp or source component. REX 3 DAC’s Gen 3 SuperPak dramatically adds to the open and transparent sound from this world-class 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.
