A friend of mine has that krell with a pair of Audience 82 floorstanders and he's dumping it for a Coda Continuum integrated. Even stereophile found that the amp clips with a 4 ohm load.

Its hard to believe for me. There are issues with 400xi if not ventilated properly in case of very low impedance dip like 2 ohms and below when played loud. I think any home audio amplifier will have problems driving those loads especially integrateds.
One of my very good friend's brother is running Krell 400xi with Tannoy
System 215 DMT II studio monitors (15" Dual Concentric with 15" Bass driver per side) and they are no easy load by any standard, on top of it the guy listens to it "LOUD". Till date the 400xi has not shut down once because of thermal issues and had shown no signs of clipping.
As far as stereophile and JA is concerned he has mentioned that amp had some problem and he faced the issue while measuring it.
