SW1X DAC II STD

SW1X Audio Design™ DAC II Performance Level 2 D to A Converter

 

DAC II is based on 2 x PCM56K DACs with more sophisticated power supplies and powerful ECC88/6N6P valve output stage with 6X5GT valve rectification. The DAC has a similar analogue character of SW1X DAC I with musical refinement and presentation on another level. The transparency and the low level resolution of DAC II matches or supersedes 24bit/32bit DAC chips. The DAC II is also available in the Special or Signature version, which is available on custom built to order basis only.

DACs II is NOS (non oversampling) by design. The signal chain looks like this:

Input > SPDIF receiver chip > 2 x current out DAC chips > I/U conversion > Single Ended, Class A, zero feedback 6N6P/ECC88 Valve Output Stage

The active I/V (current- to voltage conversion) is directly connected to the single ended class A, zero feedback, anode follower 6N6P/ECC88 tube output stage. The whole circuit has only one decoupling capacitor per channel in the signal path. Everything, including the whole signal path is wired with specially selected silver and copper wires from input to output.

 

SW1X Audio Design™ DAC II Features:

• Specially selected and harmonically matched component & material quality based on performance level 2 standard:
• AN Kaisei, Philips BC, Siemens capacitors, Allen Bradley resistors, complementary silver and copper wiring technique everywhere
• NOS (Non oversampling –zero digital domain filtering) design
• Based on 2 x PCM56 K – the most refined and highest resolving sounding 16 bit DAC chips ever produced (yes, even cleaner and more refined than most 24/32bit Delta Sigma chips) directly connected to CS8414 S/PDIF receiver
• Active I/V conversion via a special transistor (with less than 10 Ohm input impedance) with the shortest signal path directly connected to the tube grid
• Single ended, anode follower, zero feedback, 6N6P/ECC88 double triode valve output stage
• Output stage signal decoupling capacitor options a) Bosch PIO or b)  Audio Note Copper Foil Mylar in Oil capacitor
• 6X5GT double diode valve rectified CLC (choke filtered) HV power supply
• 2 separate mains transformers for the DAC and the valve output stage circuits
• Custom Germanium transistor based shunt voltage regulated power supplies around PCM56K circuit
• Supports 24Bit/96kHz digital coaxial S/PDIF signal input
• 110/115/230/240V AC mains transformers
