SW1X Audio Design™ DAC V Performance Level 5 Digital to Analogue Converter


DAC V is our currently top of the line, super DAC.

Similar to the DAC III Balanced & the DAC IV, DAC V is Signal Output Transformer (OPT) de-coupled, is amplified by Directly Heated Triodes and powered by Directly Heated Valve Rectified Quasi Dual Mono Power Supply.

Signal Output Transformer (OPT) de-coupling of the Directly Heated Valve Output Stage is the closest approximation to a truely “invisibly” sounding DAC.

Available in different versions: Special and the limited Signature version with different power output transformer options (Permalloy or SHiB and UHiB) and all Copper, Copper/Silver or all Silver wiring.

SW1X Audio Design Product Price List



We do not recommend purchasing a key system component without first auditioning it carefully, which is why we have demonstration rooms and a flexible home loan policy.

However in certain situations it can be difficult for people to get to our showroom and for those instances we can offer our mail order service.
