SW1X Audio Design™ DAC V

Performance Level 5
71A/45 DHT Digital to Analogue Converter

 

Similar to the DAC III Balanced & the DAC IV, DAC V is Signal Output Transformer (OPT) de-coupled yet is amplified by Directly Heated Triodes and powered by Directly Heated Valve Rectified Quasi Dual Mono Power Supply.

Signal Output Transformer (OPT) de-coupling of the Directly Heated Valve Output Stage is the closest approximation to a truely “invisibly” sounding DAC.

Available in different versions: Special, Classic and the limited Signature version with different power output transformer options (M6 EI, SHiB and UHiB DC cores) and all Copper, Copper/Silver or all Silver wiring.

SW1X Audio Design™ DAC V Features:

  • Pure & Elegant NOS (Non oversampling – zero digital domain filtering) R2R Design
  • Balanced (& Single Ended) Signal Output Transformer (OPT) de-coupled Valve Output Stage Topology
  • Zero NFB, Single Ended, Class A, Directly Heated Power Triode Valve Power Output Stage
  • Quasi Dual Mono, Directly Heated Double Diode Valve Rectified B+ Power Supply
  • Dynamic Element Matching (DEM) regulated by Valve Clock, powered by Valve Rectified & Choke Filtered Power Supply
  • Discrete Transistor, Shunt Voltage Regulated Low Voltage Power Supplies
