I agree the Cornwalls have been more illuminating of component changes and positioning than any speaker I’ve owned. It’s hard to make them sound “bad” as they pair nicely with almost any amp you put on them. But their capabilities have far exceeded my hopes with willingness to experiment with positioning and amps. I’ve cycled through some of the “usual suspects” recommended by reviewers and fellow owners including Luxman(590AXII), Naim(Atom and Nova), Carver(Crimson), DAC (King Maraschinos), Abbingdon Music Research(AM-777), Linear Tube Audio, and Don Sachs Valhalla. They all partner well and the Cornwalls seem to be more agnostic than most in terms of amp topology. That being said, all amps except the Valhalla were a set of trade offs and compromises with the AMR amp surprisingly being my second favorite. The Sachs Valhalla, though, checks every box on the checklist and makes the Cornwalls absolutely disappear. I stopped posting (for the most part) years ago as almost every recommendation I have acted on falls tragically short of my expectations. This is the first amp that shattered the glass ceiling of what I thought was possible...and at a price that in the world of high end audio is a steal.
