SW1X Audio Design™ DAC V Performance Level 5 D to A Converter


DAC V does not need an introduction- it is our forthcoming top of the line, signal output transformer coupled version of the DAC IV powered by Directly Heated Triodes and Directly Heated Diodes.

Available with different signal output transformer options and wiring.




SW1X Audio Design™ DAC V Features:

  • Specially selected and harmonically matched component & material quality based on the performance level 5 criteria
  • Signal output transformer coupled, DHT output stage with a choice of transformer core (HiB, SHiB and 80% Permallloy 2 x C cores) and wire materials (copper/silver)
  • NOS (Non oversampling –zero digital domain filtering) design
  • Based on 1 x TDA1541 – the most analogue sounding DAC design ever made directly connected to CS8414 S/PDIF receiver
  • Dynamic Element Matching (DEM) of the TDA1541 is driven by an asynchronous E180F valve clock with EAA91 valve rectified power supply
  • Passive I/V conversion via a single specially selected resistor with the shortest signal path directly connected to the tube grid
  • Double C core signal output transformer, zero feedback, 2x 6SL9, 2 x 245 Directly Heated Triodes valve output stage
  • 5Z3 Directly Heated double diode tube rectified C2xLC (choke filtered) power supply
  • Discrete Germanium transistor based shunt voltage regulated power supplies for the TDA1541
  • Supports 24Bit/96kHz digital coaxial SPDIF signal input
  • XLR AES/EBU or I2S input
  • 3 x 110/115/230/240V AC mains transformers

We do not recommend purchasing a key system component without first auditioning it carefully, which is why we have demonstration rooms and a flexible home loan policy.

However in certain situations it can be difficult for people to get to our showroom and for those instances we can offer our mail order service.
