SW1x DAC II Balanced Special

SW1X DAC II Balanced Special

PCM56 DAC with Active I/V 6V6 Valve Output Stage & Signal Output Transformer

The Balanced Special version is a top of the line & very special DAC II: it is the fusion of the DAC II Balanced and the DAC IV Special

This version shares the digital side of the DAC II Balanced, employes an active I/V conversions stage and borrows the 6V6 power tube output stage from the DAC IV

The 6V6 power tube output stage is de-coupled by a signal output transformer (OPT) de-coupled power tube output stage driven by the active I/V conversion stage for an even more dynamic bite.
