SW1X DAC II

PCM56 DAC with Active I/V 6N6P Valve Output Stage

DAC II comes equipped with more sophisticated power supplies and powerful 6N6P/6N30P/5687/E182CC valve output stage with 6X5GT (or 5Y3) valve rectification. The DAC II has a similar analogue & musical character akin to DAC I but with a step up in low level musical refinement and presentation on another level. The circuit design is pure and elegantly simple with only one decoupling capacitor per channel in the signal path. Everything from input to output, including the mains inlet, the whole signal path is wired with specially selected SW1X copper conductors & dielectric- the same ones that are employed in our Genesis and Opus cables.

SW1X Audio Design DAC II Features:

• Pure NOS (Non oversampling – Zero Digital Domain Filtering) R2R Design
• Selected and Harmonically matched Component & Material Quality
• Based on 2 x PCM56PK – one of the most refined R2R DACs ever produced
• Active I/V conversion via a special transistor (with less than 10 Ohm input impedance)
• Pure Class A, Anode Follower, Zero Negative Feedback, Single Ended Valve Amplification Topology
• 6N6P Double Triode Driver Valve Output Stage
• Valve rectified CLC (choke filtered) B+ Power Supply
• Discrete Transistor, Shunt Voltage Regulated Low Voltage Power Supplies
• 2 x EI core Mains transformers for Split Dual Power Suplies of Digital and Analogue

Specially Selected and Harmonically Matched Component & Material Quality

• M6 grain orient EI core Mains Transformers & Chokes
• Internally wired exclusively with our SW1X Magnum, Genesis and Opus conductors of various geometry (single strand or Litz)
• AN Copper Foil in Oil Signal Output de-coupling Capacitors
• AB 2W non-magnetic Carbon film Resistors in selected places
