Description

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. Available in either STD/SPX or in Balanced versions. The Balanced versions of the DAC III with true balanced and single ended ouputs is available in a larger chassis listed here.

DAC III SW1X

SW1X Audio Design™ DAC III Features:

  • Pure NOS (Non oversampling – zero digital domain filtering) Design
  • Selected and Harmonically Matched Component & Material Quality
  • Based on 1x TDA1541 – the most analogue sounding R2R DAC ever made
  • STD, Anode Follower, Zero Negative Feedback, Single Ended, Class A, RC (resistive loaded, capacitive de-coupled) Valve Amplification Topology
  • 6N6P or 5687 Double Triode Driver Valve Output Stage
  • 6X5 Indirectly Heated or Directly Heated 5Y3 (5R4 as an option) Valve rectified CLC (choke filtered) Power Supply
  • 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 transistor (with less than 10 Ohm input impedance) with the shortest signal path directly connected to the tube grid
  • Circuit is wired with of a specially selected copper (single strand or Litz)
  • Discrete Transistor Shunt Voltage Regulated Power Supplies for the TDA1541, SPDIF receiver and active I/V conversion
  • Supports up to 24Bit/96kHz (optional up to 48 kHz only) digital coaxial S/PDIF signal input (USB input is optional, see in options below)
  • 3 x EI core Mains Transformers & Chokes

Tube Compliment: 1 x 6X5 (5Y3 or 5R4 as an option), 1 x 6N6P (or 5687/E182CC as an option), 1 x EC86, 1 x EAA91
