I replaced a Benchmark DAC1 + Bryston BP-26 analog preamp with the Integra 9.8 and I don't believe I've given up anything.
Interesting. I guess this suggests (if you cannot hear a difference) that the jitter handling of the Integra is excellent - did you carefully A/B against the DAC1 ?
I use an Anthem AVM 20 and will eventually need to upgrade (perhaps to the D2) at some point and the Integra looks like great value. I find the Anthem 20 adequate for movies and DVD's but there is some slight audible jitter (disappointing but not surprising) and hence I prefer DAC1 as the source for music.
