SW1X DAC III STD

SW1X Audio Design™ DAC III STD 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™.

DAC III builds upon the refinement of the SW1X DAC II and adds additional level of organic & analogue envelope to the sound.  The sonic character becomes indistinguishable from analogue playback when combined with analogue sounding digital transport. Signature version of the DAC III is available on custom built to order basis only.

 

 

SW1X Audio Design™ DAC III Features:

  • Specially selected and harmonically matched component & material quality
  • NOS (Non oversampling –zero digital domain filtering) design
  • Based on 1x TDA1541 – the most analogue sounding DAC chip 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
  • Active I/V conversion via a single specially selected Silicium (or Germanium on request) transistor (with less than 10 Ohm input impedance) with the shortest signal path directly connected to the tube grid
  • Anode follower, zero feedback, 6N6P double triode valve output stage
  • Output stage signal decoupling capacitor options a) Tesla PIO or b)  Jensen/ Audio Note Copper Foil in Oil capacitors
  • 6X4 indirectly heated or GZ34 (5C4M) tube rectified CLC (choke filtered) tube output stage power supply
  • Circuit is wired with of a specially selected copper (single strand or Litz)
  • Discrete Germanium transistor based shunt voltage regulated power supplies for the TDA1541, SPDIF receiver and active I/V conversion
  • 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

 

Optional Extras:

a) 2 x Audio Note Copper foil, mylar in Oil signal output decoupling capacitors

b) 4 x Black Gate capacitors around TDA1541

c) Audio Note 2W copper, non- magnetic, tantalum film resistors on plates of the output tube

d) the STD version of DAC III can be ordered with either US made 5687/E182CC or Soviet 6N6P

Premium 6N6P from the 60s or

Premium vintage NOS black plate Tung Sol 5687/E182CC output tube

e) directly heated vintage 5R4 type of tube (from the 60s) in the PSU

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

g)  output wiring is normally one pair in fine silver and other is copper (by default),

This way one can fine tune the sound by using either output.

optional is all silver or all copper wiring

h) Tubed clock USB input, powered by an separate transformer

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.
