For sale is SW1X Audio Design DAC 1 Signature with Audio Note Kaisei and Black Gate capacitors fully silver wired in used but otherwise in immaculate condition.

The DAC on offer is a result of a trade in as one of our customers decided to go for the DAC II.

The Signature version is the limited edition version, which is never held in stock and is available on custom order basis only.

The list price including VAT of the new Signature High Gain version of the DAC 1 is currently GBP 2000.

There is an excellent opportunity to get the DAC 1 Signature for less here without any waiting time.

• NOS (Non oversampling –zero digital domain filtering) design
• Based on 1x TDA1543 – one of the most analogue sounding DAC chips ever directly connected to CS8414 S/PDIF receiver
• active I/V conversion via a special transistor (with less than 10 Ohm input impedance) read more about it here
  http://sw1xad.co.uk/technology_post/passive-vs-active-iv-conversion/
  with the shortest signal path directly connected to the tube grid
  the major advantage is that dynamics are more realistically reproduced, unlike with the common resistor based I/V conversion approach
  and unlike other TDA1543 based DACs on the market our DAC is excellent at reproduction of low level musical information especially at lower volume levels
  
• pure class A, zero feedback, single ended, double triode 6N6P tube output stage
• CLC (choke filtered) tube power supply
  
• Shunt voltage regulators everywhere (much smoother and more analogue sounding)
• supports 24Bit/96kHz digital coaxial S/PDIF signal input
  
• 110V/120V/220V/230/240V mains transformers on request
• Designed and Handcrafted in England
  

For the best possible sound, we pay utmost attention to material and component quality:

• We only use finest and carefully selected audio components such as Black Gate, Kaisei, Elna Silmic, Cerafine, Allen Bradley resistors, Telefunken diodes, PIO, AN or Black Gate output capacitors
• The PCB has no mask on the bottom side and all conductive traces are covered with gold and a special varnish for a for a more open and detailed sound
• Mains input wiring as well as S/PDIF and analogue out is wired in pure silver
• Silver plated RCA connectors
