SW1X DAC I Special X

SW1X Audio Design™ DAC I Special Performance Level 1 D to A Converter with USB I interface and valve rectified power supplies

 

SW1X DAC I Special is the maxxed out circuit of DAC I and USB I in one chassis with addition of fully choke filtered and indirectly heated valve rectified power supplies.

DAC I Special X has 2 inputs: USB and SPDIF but could also be configured (on request) as I2S directly connected to TDA1543 via USB input only.

This is a high end entry level solution to a musical, organic & analogue sounding digital setup- just add an analogue sounding digital transport and re-experience your collection of music.

 

 

SW1X Audio Design™ DAC I Special Features:

 

USB I interface section

  • Master clock is based on low noise EC88 triode tube powered by a separate transformer and is output transformer de-coupled from the rest of the circuit
  • Power supply of valve master clock is valve rectified
  • Custom Shunt regulated power supply based on a Germanium transistor for the USB/SPDIF receiver/transmitter
  • separate power transformers: one for the master clock and one for the USB receiver / tube S/PDIF digital signal output stage
  • CLC (choke filtered) valve clock and valve SPDIF output stage power supply
  • E180F tube buffered S/PDIF output stage
  • Plug’n’Play with USB OTG- no drivers required for Mac, Windows, Linux and Android operating systems (works with Samsung Galaxy and Android TV box, iPad 3)
  • Asynchronous USB data transfer mode (sounds best with a dedicated, unpowered USB interconnect such as SW1X AERO 5 USB)
  • Bit perfect data transfer with Kernel streaming, ASIO and WASAPI support
  • Resolution 16/24 bit, 32KHz, 44.1KHz, 48KHz, 88.2KHz, 96KHz (higher resolution than 24 bit is not supported by S/PDIF anyway)

Ordering

We do not recommend purchasing a key system component without first auditioning it carefully, which is why we have demonstration rooms and a flexible home loan policy.

However in certain situations it can be difficult for people to get to our showroom and for those instances we can offer our mail order service.
