I've heard the Peachtrees several times, including in high end audio demos. One such was an iPod Nano into the Peachtree, using the pre-outs to bi-amp some Maggies. Sound was fabulous and it showed off just how good both the DAC and line stage are in the Peachtree. For your purposes the bult-in power stage would be plenty as well. Plus some of the current models can dock an iPod for a direct digital feed to their built-in DAC.
Have you considered the idea of some powered speakers (e.g., AudioEngine A5) and the Benchmark DAC-1 PRE?
