jon2020,
I can't speak on the difference between going direct from the Aeris dac to power amps vs through the Corus preamp. The only dacs I experimented with going direct were the PS Audio DSD and Bricasti M1. I already had the JR Continuum S2 integrated amp when I purchased the Aeris and never had an opportunity to try it direct. The JR 625 S2/Corus combination is a significant step-up from the Continuum S2, but I can't honestly say which component(625 S2 or Corus) has the most impact, because I received them at the same time.
I will say, in my system the Aeris DAC has more detail, images better, and has a slightly larger soundstage than the Bricasti M1.
In addition, I will admit that I prefer a sound on the slightly warm side of neutral and that's what my current combination provides.
