SW1X DAC III

SW1X Audio Design™ DAC III

Performance Level 3

Digital to Analogue Converter

Re-experience the legendary classic NOS R2R DAC powered by valves at its full glory, re-incarnated by SW1X Audio Design™.

DAC III builds upon the refinement of the SW1X DAC II and adds additional level of organic & analogue envelope to the sound. The sonic character becomes indistinguishable from analogue playback when combined with analogue sounding digital transport. Available in either single-ended (SE) or in Balanced versions. The Balanced versions of the DAC III is equipped with signal output transformers (OTPs) providing true balanced and single ended ouputs.

For maximum synergy, musical & analogue character, all SE & Balanced versions were designed to be paired with our VDT Digital Source products.

DAC III is currently available in the following specifications:

Single Ended (compact chassis)
Single Ended USB (with USB interface in larger, full size chassis)
CDP III (with VDT 1/2 in full size chassis)
Balanced/Special/Classic/ Signature (full size chassis) + VDT Digital Source

The SW1X DAC III is quite simply one of the best DACs I have ever heard – Dagogo.com
