I cannot say much about Krell, as I've never owned any, but the Odyssey Stratos-yes. I owned a pair for a few months. Found them harsh in upper treble and "hummed" in my system. The Odyssey had some awsome attributes- great soundstage, depth, bass and presence, but one big BUT- fatigue. I could not listen to these for long periods due to the graininess in the treble. May have been cables, may have been my room,etc. The best match for my Avalon Eclipse were a pair of BAT 60s.
I cannot recommend The Odessey.
