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:

  • Zero oversampling – elegant, zero digital manipulation design
  • Discrete Germanium transistor based shunt voltage regulated power supplies
  • Dynamic Element Matching (DEM) of the TDA1541 is powered 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
  • Super HiB C-core signal output transformer, zero feedback, 2x 6SL9, 2 x 245 Directly Heated Triodes valve output stage
  • 5Z3 or 80 Directly Heated double diode tube rectified C2xLC (choke filtered) power supply
  • XLR AES/EBU or I2S input
  • 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)
  • Black Gate capacitors around TDA1541
  • Audio Note 2W silver, non-magnetic, tantalum resistors in the I/V conversion
  • Audio Note 2W copper, non- magnetic, tantalum film resistors on plates, cathodes, power supplies and I/V conversion
  • Inter-stage signal decoupling capacitor options are Audio Note 1. Copper Foil in Oil or 2. Silver Foil capacitors


Optional Extras:

a) Black Gate capacitors in the power supplies

b) 2 x HiB double C-Core mains transformers for the TDA1541 and DHT/DHD power supplies

c) Fine silver wiring

d) AN 2W silver, non-magnetic, tantalum resistors

e) Fine silver windings on the signal output 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.
