SW1X DAC II Balanced Special

SW1X Audio Design™ DAC II Balanced

Performance Level 3

Digital to Analogue Converter

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.
