John Atkinson is not impressed due to inconsistent performance of Benchmark Media DAC1 USB when playing 16 bit, 44.1 kHz files via USB. Where is the jitter performance via USB? Was it too bad to publish?
Last time I believe John Atkinson preferred TosLink to USB performance of Bel Canto e.One DAC3 due to quality and high jitter via USB.
I think only PS Audio DAC III is left now. Does anybody know about its jitter performance?
