The one frontier I haven't ventured across is the area of a separate DAC. The two I am looking at are the new Benchmark and the new PS Audio. The PS Audio is slightly cheaper due to the deals a dealer in Des Moines IA is giving on them. I like the idea of the USB connection as a little bit of future-proofing (like I keep things long enough to worry about the future :o ). Has anyone compared these? I would be using it with either a Jolida CDP or a Rotel RCD-1072. Any others in this price range new/used I should consider?
