About the
Audio Note DAC 3.1x/II Balanced.

The DAC 3.1x/II Balanced opens the Level 3 tier. No-oversampling Analogue Devices AD1865 conversion, valve output stage feeding a copper-wound balanced output transformer. Pairs naturally with the P4 Balanced Tonmeister or any AN UK balanced power amp downstream.

Variations

Audio Note DAC 3.1x/II Balanced across 6 variants.

Six DACs climbing through the Audio Note UK tier ladder. The brand uses non-oversampling (NOS) R2R conversion throughout — no delta-sigma, no upsampling. The output stage moves from solid-state at the entry tier (0.1x) to fully valve-based + silver-wired by Level 5 (DAC 5). Each tier matches the rest of the catalogue: a DAC 2.1x belongs with a Level 2 amp / preamp pairing.
