I have to say georgehifi according to you the only amps anyone should EVER own are Gryphon, “big” Krells, or D’Augostino, maybe a JC1 pair. It’s the same discussion, the same argument, the same bla, bla, bla. Sure you are a fan, those are some great designs, but get off it. They aren’t the end all be all, there are many, many excellent amps out there, a lot of which will drive just about anything. Given the lower sensitivity of speaker designs overall these days, premium designers do pretty well to design amps that do very well. Lots of opinion, not much substance here.
