SW1X DAC II Balanced

SW1X Audio Design™ DAC II Balanced Performance Level 2/3

D to A Converter

The Balanced version is a non compromise tube output stage DAC II and a smaller brother to the DAC III Balanced.

The number of PCM56 R2R DACs is doubled to 4 pieces (2x per channel), whereas the STD & SPX versions employ 2 x PCM56 (1x per channel) .

Similar to the DAC III Balanced, DAC II Balanced comes equipped with a EL82/EL84 power tube output stage. The step up in transparency over the STD & SPX versions is provided 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.

Also available in Balanced Special version with 6V6 tube output stage similar to the DAC IV.

SW1X Audio Design™ DAC II Balanced Features:

Pure & Elegant (Non oversampling – zero digital domain filtering) true NOS R2R Design
Digital side is based on 4 x PCM56 (2x per channel) R2R DACs
Balanced (& Single Ended) Signal Output Transformer de-coupled Valve Output Stage Topology

Digital Transport Product Overview

SW1X DAC II Balanced

PCM56 DAC with Active I/V EL84 Valve Output Stage & Signal Output Transformers

Expanding upon the DAC II standard, number of PCM56 R2R DACs in the DAC II Balanced is doubled to 4 pieces (2x per channel).

Similar to the DAC III Balanced, DAC II Balanced comes equipped with a EL82/EL84 power tube output stage. The step up in transparency over the standard version is provided 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.

SW1X II Balanced

A few weeks ago, I bought a DAC II balanced from Ajamson Audio. It is still in the break-in period, but the sound is getting better and better. I'v listened to many DACs, including the Audio Note 3.1, and I don't regret choosing the SW1X, even though I couldn't listen to it beforehand. Finally, a DAC that lets me hear the real sound of a piano. Thank you, and congratulations to the DAC.
