in the last 2 years I have had these DACs
PS Audio DL3
Benchmark USB DAC1
MHDT Labs Havana (stellar, btw)
Musical Fidelity TriVista
Bel Canto DacIII
Tube Audio Design PreDAC
Berkeley Alpha
Bryston BDA-1 (current and future)
I tested the Bryston and Berkeley at the same time, and I did think the Berkeley was all around a little better, more extended, extremely rich, but the Bryston was bit warmer, and the Berkley did not justify, in any way the extra cost. I couldn't be happier with the Bryston, it's great.
