Convertitore D-A SW1X Audio Design™ DAC III

Pure NOS (non oversampling) R2R Design

Sperimentate il leggendario DAC classico TDA1541 alimentato a valvole al suo massimo splendore, reincarnato da SW1X Audio Design™.

Il DAC III si basa sulla raffinatezza del DAC II SW1X e aggiunge un ulteriore livello di inviluppo organico e analogico al suono. Il carattere sonoro diventa indistinguibile dalla riproduzione analogica se combinato con un trasporto digitale dal suono analogico. La versione Signature del DAC III è disponibile solo su ordinazione.

Descrizione

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

 

Optional Extras:

  • AN Copper foil, mylar in Oil signal output decoupling capacitors
  • Black Gate capacitors around TDA1541
  • AN 2W copper, non- magnetic, tantalum film resistors on plates of the output tube
  • 5687/E182CC or 6N6P Premium 6N6P from the 60s or Premium vintage NOS black plate Tung Sol 5687/E182CC output tube
  • Directly heated vintage 5R4 type of tube (from the 60s) in the PSU
  • Additional choke filtering on the DEM clock tube PSU for the TDA1541
  • USB input with a tube master clock, powered by an separate transformer
  • 2 x HiB double C-Core mains transformers for the TDA1541 and DHT/DHD power supplies
