SW1X Audio Design™ DAC III Signature Features:

  • Specially selected and harmonically matched component & material quality
  • NOS (Non oversampling –zero digital domain filtering) design

  • Dynamic Element Matching (DEM) of the TDA1541 is powered by an asynchronous E806S valve clock with EAA91 valve rectified, choke filtered power supply
  • Active I/V conversion via specially selected Germanium transistor (with less than 10 Ohm input impedance) with the shortest signal path directly connected to the tube grid
  • Anode follower, zero feedback, E182CC double triode valve coupled output stage
  • 5C4S tube rectified CLCLC (2x choke filtered) HV valve output stage power supply
  • Audio Note Copper Foil Mylar in Oil or Jensen copper foil in oil output signal decoupling capacitor
  • Custom Germanium transistor based shunt voltage regulated power supplies
  • Supports 24Bit/96kHz digital coaxial S/PDIF signal input
  • 3 x 110/115/230/240V mains transformers

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.
