I've heard the Krell KAV-300i and the Classe CAP 151 in different settings. The Krell sounded harsh and too bright for me, but it might have been the speakers and CD player. I listen to a wide variety of music and the Classe with the Classe CDP .3 and Joseph Audio speakers in a small room sounded much warmer and relaxing long term, no fatigue, as well as being duynamic and so musical. Of course, you see much more used Krell, noone seems as familiar with the Classe.
