SW1X Audio Design™ DAC X

Statement Level X
DHT Digital to Analogue Converter


DAC X is our Statement Level X Digital to Analogue Converter.

Statement Level X represents the pinnacle of SW1X engineering and DAC X is a culmination of all our know how and technology from our DAC product line up (DAC I-V) in one chassis.

It is the most musical, organic & natural sounding DAC we have designed to date. The musical performance of the DAC X re-defines what was thought is possible from a digital playback.

When partnered with a matching VDT digital source, its analogue character is indistinguashable from the best RTR and Vinyl playback.
