No simple answer, but;
While I agree integrateds are a compromise, the Technics SU R 1000 COULD be the one to own
I do not own your kit, but my Audio Alchemy DDP-1 + PS 5 is a pretty good preamp/dac. Last 2 years I tried a lot of power amps, and they all sounded different. The one that stood out from the crowd is my LSA Voyager GaN 350 (MSRP $3000 (same tech as in the Technics)
