It's not easy to realize that before you tried some different things. This is part of my own experience and I think its worth trying. (Friendly advice).
For sure Krell Master Reference are good, but you know, my Krell 350 Mc modified are to drive my Sf Guarneri Memento at work, so it's already kind of crazy system to have in a dental klinik.
My Krell are doing very well I think. The are still breaking in and it's about 120h right now.
I made a test a week ago and compared against my Gryphon. Gryphon is more liquid, smooth, more texture and more air in the presentation. Gryphon also has some more texture and power in the low frequencies. I feels like the bas is bigger and fills the room better. But this is something that has been a bit evened out during the break in period.
Krell loves when I play at about 100db. Gryphon starts to get problems when I play very loud and above 100-105db due to just 150 Watt class A. That is seldom though.
When Krell 350 MC are broken in they are up to a final test against Gryphon and then the will be moved to my dental clinic.

Apexorca, Glad to hear the Krells are coming along. It's not surprising about the Gryphon being more nuanced than the Krells. But your Krell's retain special qualities that can't be beat by modern day amps. In my experience they have a "presence quality" that my Macs don't have, a special "live performance" quality that is unrivaled in my experience. I'm sure you have heard it and know what I mean. And your right: the louder you play the more prominent this quality becomes. These mono amps you have are special. Hang on to them. Don't ever sell them.
In regards to power, I have paid special attention to it. As you might have surmised from my above comment to NZ2421291 I use a Transguard TG60 whole house surge protector that protects the house from power surges including lightning. It has significant filtering of noise. And then I have a 400 amp fuse box (400 amp service) and a secondary fuse box providing the necessary circuits for my 4 dedicated 20 amp lines using number 10 wire. I agree that power conditioners and cords help but are no substitute for raw power. My system has zero audible hum and noise at 100% volume at all inputs with all equipment on except my tuner.
