Olpas, I have the Audio Note Kits Ccore output and interstage monos. They are fantastic amps, and I'd very much like to hear them on Duos but I have not. On my Cain Single Ben horns (98dB) they are quiet at idle. Astonishing control and deeply textured and expressive true to the AN sound, if you will.
Sounds like you've chosen your amps, but if you decide on the diy route, I'd strongly suggest you check out the AN gear and let us us know what you find.
