SW1X DAC V

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
