I'm currently the owner of an HK AVR 630. My experience with the unit has been pretty good, but I sometimes find it a bit too 'up front' for my tastes. Not that the sound is particularly 'bright', its just that every now and then the sound seems to leap out of my speakers and grab me by my eardrums, if that makes any sense. I also find that, along with several AV amps I've tried its utterly useless with music. I was wondering if any of you had experience of listening to a Harman amp in comparison with the Arcam AVR 250 or 300, which I understand are very good with music, as I am considering changing to one of these units. Do any of you think this would be a wise move?. I'm looking for a smooth but powerful sound that avoids any harshness or 'glare'. Something that's at least reasonably 'musical' is also desirable.
