I would suggest that you look into the Pas INT30A!
I am a long-time Accuphase fan, if price is not an issue I will stick with Accuphase 560 (biased). My only concern is the quality of a DAC card v.s. a dedicated DAC. Phono cards are pretty mature these days but DACs evolve every year. As an alternative, I'll stay with a separate DAC and an PrimaLuna Premium Integrated. The advantage is (1) you get maintainance-free tube sound, (2) no need to wait for Class A amps to warm up to the right temperature to sound good.
I own the Luxman L-590ax integrated amplifier and like it very much. For me, the music is fuller, has more detail and has great bass control. I am hearing many more things than I did with the Ayre AX-7e amp (previous amp). The mid range is outstanding. I do not understand but it seems classical music sounds better on the Luxman than the Ayre. The music is clearer, more airy and easier to listen to. Overall, the Luxman amplifier sounds excellent in my system. My source is the Ayre CX-7e MP CD player running balanced (Harmonic Technology Magic Link Two interconnect XLR cable) into the Luxman amp connected (Synergistic Research TESLA Quad Speaker Cable) to the Sonus Faber Audio M Speakers on Sonus Faber stands.
I believe it is the class A operation plus the wonderful design of this unit that makes it sound so good.
I suggest you give it a listen. You really need to audition this unit and the other amplifiers you are considering. I would also listen to the Pass Labs Class A amplifier (INT-30).
