I use the Benchmark DAC 1 with headphones and the results are superb, IMO - great transparency and dynamics, crystal clear and not bright or etched. I'm using it with a transport, not a server, and in this set-up a good transport and fine digital cable make all the difference.
With a server, I assume you'll use the USB input on the Benchmark, and all the reviews say the Benchmark has an excellent implementation of the USB - better, e.g., than the Bryston dac and some others.
