SW1X DAC III SPX

This DAC is in excellent condition and will amaze you.

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
