Best Amp/ Pre Amp for PSB Imagine T2

I am setting up my first audio system & just bought a pair of PSB Imagine T2s. Now I am looking to buy an amp/pre amp or integrated amp for these speakers. All my music is digital on a PC (or that is where I'd like it to be). My budget is 2-2.5k . Would greatly appreciate some advice.
Here are some that I've considered so far:
NAD390DD
SimAudio Moon Series
Bryston B60 (need a DAC)
