Welcome to AC. My friend has a pair of Nola KO's. Drives them with Quicksilver V4 monos.
Interesting takeaways so far:
1. Carl has only ever shown the KO's with tube amplification at audio shows, and to my knowledge, he's never shown them being driven with more than 100W of power.
2. Your friend drives them with 170W tube monos
3. The fellow I bought them from drove them with a 400W ML solid state
My big question to myself:
Do I really need to prioritize this much power?
Integrated amplifiers I've been hunting for used:
Audio Research GSI75 (75W)
Line Magnetic 805 (50W)
Others I've been considering:
Vinnie Rossi LIO (25W)
Rogue Cronus Magnum (100W)
Roksan Blak (150W)
Luxman 590 (30W) or 509 (120W)
Gamut DI-150 (150W)
I'm struggling to find much Nola info on here, but if someone could point me in the right direction, I'd really appreciate it!
