@yyzsantabarbara Thanks, good feedback. What speakers were you driving with the BM stack?
I looked into the Krell 300i some years ago. On paper at least, it didn’t seem like a good fit with my system. Lux and Krell have a reputation among some for leaning towards an analytic sound, and right now, the last thing I want to do is to replace my brittle (or as STereophile puts it "dry"!) Class Ds with something that is not as tubelike as I can manage.
For reference, I’m an old Quad hobbyist, having owned many 1950s & 1960s Quad valve components at one time or other. For 20 years, my main system was a pair of lovingly restored ELS-57s and Quad 2 monoblocks. So Class D, Luxman, Krell -- maybe even Devialet! -- might not be a good fit in a system that already tilts a bit in the "etched" direction.
