Best integrated for PSB Imagine T2's


I have an NAD C390DD all digital integrated amplifier. I am considering a big improvement in a DAC, as in a PS Audio Perfectwave DAC. This along with my Project Xtension 10 turntable/musical surroundings nova phenomena phono preamp, would give me quality analog signal inputs from all my sources. Considering an upgrade to an integrated that could better process analog to my PSB Imagine T2 speakers with a big improvement in SQ, any thoughts on an endgame amp for around 5 to 6,000?

I'd blow off all your other component plans and get a pair of Marten Django's or Vandersteen Quatros and a Parasound Halo. 

Bryston looks good! Will look into it. m-db, the Martin djangos are $10,000 speakers! I have PSB Imagine T2's, but am looking for an amp that will make them sing. I don't know, perhaps $5000 is too much to spend for a pair of $3500 speakers. I am going to keep looking
I have PSB Imagine T2's hooked up to a Line Magnetic 518ia (22 wpc). This amp powers the T2's just fine...I am never past 11 o'clock on the volume control even listening at my "max."  LM has released the 508ia since I bought my 518 and is 45 wpc I believe if you think 22 wpc isn't enough. The 518ia is a beautiful sounding 845 SET amp in my opinion. That said.....I would love a pair of Vandersteen Quatros as recommended by m-db above :). The T2's are very nice but would probably be up for an upgrade if I were wanting to make a significant change. Good luck....let us know what you decide.
