SW1X Audio Design™ DAC II Balanced
Digital to Analogue Converter
The Balanced Special version is a top of the line & very special DAC II: it is the fusion of the DAC II Balanced and the DAC IV Special.
This version shares the digital side of the DAC II Balanced, employes an active I/V conversions stage and borrows the 6V6 power tube output stage from the DAC IV.
The 6V6 power tube output stage is de-coupled 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.
SW1X Audio Design™ DAC II Balanced Features:
- Pure & Elegant NOS (Non oversampling – zero digital domain filtering) R2R Design
- Balanced (& Single Ended) Signal Output Transformer de-coupled Valve Output Stage Topology
- Digital side is based on 4 x PCM56 (2x per channel) R2R DACs
- 6V6 Power Output Tubes, Zero NFB, Class A, Valve Output Stage
