I'd also recommend the Ascend Acoustics CBM-170 SE for the front 3 (mains and center) and the HTM-200 for the rears. The Emotiva subs would be a good choice for your budget.
Ascends would do Phish recordings proud.
Both the NHT and Ascend's will be able to provide natural speech/vocals which is very critical to Trey's voice because crappy speakers will bring out sibilance in some Phish recordings.
