SW1X Audio Design™ DAC IV Performance Level 4 D to A Converter


DAC IV is a further development in musical scale & refinement of the already magical sounding DAC III powered by Power Output Valves and Directly Heated Diodes (DHD) in the power supply. The DHD Valve power supplies are 2 x choke filtered and quasi dual mono in design. Accomodating everything in one chassis without interference of magnetic fields proved to be a real challenge but having everything housed  in one chassis with much shorter signal paths turned out to be very rewarding in the end.

The sonic presentation of the DAC IV is a another step up relative to the DAC III; its presenation of music is more mature and is on a larger scale. The transients are presented with shocking dynamic bite, making it probably the most dynamic DAC currently in production. In a right setup, the illusion of vocalists performing in front of us and the dynamic impact of instruments appearing so real it becomes scary at times. Signature versions of the DAC IV with silver wound OPTs is limited in availability and is available on custom built to order basis only.
