SW1X DAC V

45 DHT Output Valve Digital to Analogue Converter

Similar to the DAC III Balanced & the DAC IV, DAC V is Signal Output Transformer (OPT) de-coupled yet 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 truly “invisible” sounding R2R DAC.
