Both are obviously very nice amps. For me, I’d consider a McIntosh MA-252 integrated. At 100W/ch that’s more than adequate power and the hybrid tube preamp/solid state power amp should match up nicely with the Cornwalls. And I personally love the retro-styling, especially paired with classic speakers like yours. At under $5,000, it’ll also save you a few thousand dollars to put towards a nice streamer or vinyl rig.
