SW1X Audio Design™ DAC II Balanced Performance Level 2/3
D to A Converter
The Balanced version is a non compromise tube output stage DAC II and a smaller brother to the DAC III Balanced.
The number of PCM56 R2R DACs is doubled to 4 pieces (2x per channel), whereas the STD & SPX versions employ 2 x PCM56 (1x per channel) .
Similar to the DAC III Balanced, DAC II Balanced comes equipped with a EL82/EL84 power tube output stage. The step up in transparency over the STD & SPX versions is provided by a signal output transformer (OPT) de-coupled power tube output stage driven by the active I/V conversion stage for an even more dynamic bite.
Also available in Balanced Special version with 6V6 tube output stage similar to the DAC IV.
