SW1X DAC II Tube Amps the Sophia Electric EL34-ST vacuumThe SW1X DAC II steps up to the PCM56, widely regarded as one of the most refined and musical 16 bit R2R DACs ever manufactured, in a dual mono NOS design with a more sophisticated power supply and a powerful 6N6P valve output stage. The result is a meaningfully more refined and nuanced presentation than the DAC I while retaining the same pure NOS philosophy of zero oversampling and zero digital filtering.
