SW1X Audio Design™ DAC I Special Performance Level 1 D to A Converter
On special request of our customers, we are proud to offer the DAC I at its full glory with choke filtered and valve rectified power supply. This is a high performance 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:
- NOS (Non oversampling –zero digital domain filtering) design
- Selected and Harmonically matched Component & Material Quality
- Based on 1x TDA1543 – one of the most musical and purist DAC chips ever made directly connected to CS8414 S/PDIF receiver
- Active I/V conversion via a special Germanium transistor (with less than 10 Ohm input impedance) with the shortest signal path directly connected to the tube grid
- the major advantage is that dynamics are more realistically reproduced, relative to passive 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
- STD, Anode Follower, Zero Negative Feedback, Single Ended, Class A, RC (resistive loaded, capacitive de-coupled) Valve Amplification Topology
- 6N6P Double Triode Driver Valve Output Stage
- Signal de-coupling capacitor options a) Tesla PIO or b) AN Copper Foil in Oil capacitors
- 6X5GT valve rectified CLC (choke filtered) HV power supply
- Discrete Transistor, Shunt Voltage Regulated Low Voltage Power Supplies
- Supports up to 24Bit/96kHz digital coaxial S/PDIF signal input
Optional Extras:
a) Audio Note Copper foil, mylar in Oil signal output decoupling capacitors
b) Audio Note 2W copper, non- magnetic, tantalum film resistors on plates of the output tube
c) the Special version of DAC I can be ordered with either US made 5687/E182CC or 6N6P Premium 6N6P from the 60s or Premium vintage NOS black plate Tung Sol 5687/E182CC output tube
d) semi directly heated vintage 5Y3/GZ34 type of tube in the PSU
e) output wiring is normally 1 x pair in fine silver and other is copper (by default), This way one can fine tune the sound by using either output. optional is all silver or all copper wiring f) Tubed clock USB input, powered by an separate transformer
Note: Due to SW1X Audio Design’s ongoing research and development process, specifications are subject to change without notice.
