SW1X DAC III Special

SW1X Audio Design™ DAC III Special Performance Level 3 D to A Converter

 

Re-experience the legendary classic TDA1541 DAC powered by valves at its full glory, re-incarnated by SW1X Audio Design™.

The Special version is a further refinement of the SW1X DAC III and a smaller brother to the DHT powered DAC IV. The main improvement over the STD version is in larger spatial presentation, more natural harmonics and dynamic realism, which is provided by even more powerful EL84/EL86 power pentode (triode connected) tube output stage driven by the mighty 6N6P double triode. Super HiB transformer de-coupled Balanced version and the limited production Signature version of the DAC III is available on request.

SW1X Audio Design™ DAC III Special Features:

  • Specially selected and harmonically matched component & material quality Performance level 3/4
  • NOS (Non oversampling –zero digital domain filtering) design
  • Based on 1 x TDA1541 – the most analogue sounding DAC ever made directly connected to a SPDIF receiver
  • 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
  • Discrete Germanium transistor based shunt voltage regulated power supplies for the TDA1541 & SPDIF receiver
  • Anode follower, zero feedback, 1 x double triode 6N6P driver to the Super HiB choke loaded 2 x EL86 power pentode (triode connected) SE valve output stage
  • Output stage and interstage signal decoupling capacitor are Audio Note Copper Foil in Oil capacitors
  • 5R4 directly heated or GZ34 (5C4M) tube rectified CLC (choke filtered) power supply
  • Circuit is wired with of a specially selected copper (single strand or Litz)
  • Supports up to 24Bit/96kHz digital coaxial S/PDIF signal input (USB input is optional, see in options below)
  • 3 x 110/115/230/240V AC mains transformers (HiB double C-core available as an option)

 

Optional Extras:

a) Black Gate capacitors around TDA1541

b) Audio Note 2W silver, non-magnetic, tantalum resistors in the I/V conversion

c) Audio Note 2W copper, non- magnetic, tantalum film resistors on plates, cathodes, power supplies and I/V conversion

d) Audio Note Silver Foil capacitors in inter-stage and ouput stage signal decoupling option

e) Additional choke filtering on the DEM clock tube PSU for the TDA1541

f) Circuit is normally wired with specially selected copper but can be ordered with fine silver wiring (including power inlet)

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

Ordering

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.
