SW1X DAC III Balanced

EL84 Valve Power Digital to Analogue Converter

The Balanced version of the DAC III is a non-compromise valve output stage design DAC III, equipped with Signal Output Transfromers (OPTs), a smaller brother to the DAC IV and DHT output stage based DAC V. The step up in transparency of the Balanced over the SE version is provided by a signal output transformer de-coupled EL84 power pentode (triode connected) tube output stage driven by the mighty 6N6P double triode.
