DAC II Balanced Special

SW1X Audio Design™ DAC II Balanced

Performance Level 3
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
  • Active I/V conversion via a special transistor (with less than 10 Ohm input impedance)
  • Discrete Transistor, Shunt Voltage Regulated Low Voltage Power Supplies
  • 5U4GYB/5R4GYB Directly Heated Valve rectified C2LC (choke filtered) B+ Power Supply
