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?

By the way,  the bass from the Creek into the T2s is just so nice and tight.  I can make the curtains move if the speakers are closer to the wall. 

The Primaluna is my favorite though.

That's great you've been able to use a variety of amps with the T2. Could you go into more detail of the sonic signature of the Nova 300 and the Creek 100A with the T2?

Cheers,

I responded earlier discussing my current integrated LM 518ia and T2's. Prior to this, and overlapping for about a year, I had a Primaluna Prologue Premium integrated amp. Primaluna is an excellent integrated. Sonically I preferred the EL34 tube sound but it didn't seem to have quite enough "oomph" for me. Rolling in the TungSol 150s added that oomph with more and tighter bass, but the creamy mids suffered. The LM seems to give me both and I would love to hear the new LM 508 integrated. I sold the Primaluna. 

But the Primaluna is a great amp. I would suggest if you go Primaluna that you should get the Dialogue Premium at a minimum (not the Premium) and if you can swing it the Dialogue HP would make the T2's sing as jbhiller says. 
Edit:  meant to say get the Dialogue level not the "Prologue" which is what I had. Sorry.......
Fantastic. Okay, so the primaluna was your favorite with the T2's? I can swing the HP primaluna....so you had the prologue and it was still your favorite even with inadequate power? Sounds fascinating...can you please tell me why you preferred a lower power amp to the others? My concern is that with my NAD, with all digital circuitry, I am not getting the best sound quality for my T2 speakers out of my analog turntable setup. Also, I would probably get a really good DAC which of course would also provide an excellent analog signal into the amplifier from the streamer and cd transport. Trying to figure this out....I am a bit of a newbie
