SW1X DAC III

DAC III introduces TDA1541 DAC and 6N6P Double Triode Valve Output Stage, adding additional level of organic & analogue envelope to the sound over DAC II.  The sonic character becomes indistinguishable from analogue playback when combined with analogue sounding digital transport. Available in either single-ended (SE) or in Balanced versions. The Balanced versions of the DAC III is equipped with signal output transformers (OTPs) providing true balanced and single ended ouputs.

SW1X Audio Design™ DAC III Features:

• Pure NOS (Non oversampling – zero digital domain filtering) R2R Design
• Selected and Harmonically Matched Component & Material Quality
• Anode Follower, Zero Negative Feedback, Single Ended, Class A, RC (resistive loaded, capacitive de-coupled) Valve Amplification Topology
• 6N6P Double Triode Valve Output Stage
• 6X5 Indirectly Heated or Directly Heated 5Y3 (SE version) 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
• 3 (4 x on USB version) x EI core Mains Transformers & 2 x Chokes
