I’m hoping to get a pair of the Hypex Nilai monos at some point in my journey. With a really nice tube pre of course. These are at about 260w @8ohms, but the 4ohm rating is well over 500w. And stable / unshakable with super low noise way down past that. They’re reviewed not just for their power capability, but for sounding very natural. Comparable to class A in some respects.Alpha Audio has spent a lot of time with the Hypex Nilai offerings in some comparo vids with listening examples:

Apollon Audio has their designs around the Nilai as well: https://apollonaudio.com/product/hypex-nilai-500-m-monoblock-amplifier/
But if you were ok with foregoing that power requirement, those new Crecsendos by Laiv seem really promising, and the GaNfet sound seems to be primo. Hoping those new Class D Audio amps are a complete redesign. Nice to know folks here like them and I’ll have to check those out. Their first amps on the market were presumed no bueno, but I have no direct experience with them.
