I do often wonder though why my system sounds so harsh with certain genres! The thing is one Naim user will listen to music where Naims faults or signature sound may not show up so much, personally I listen to a lot of music which was made to sound harsh and raucous, so an amp which carries this sonic signature is I guess too much. All the criticisms made by others here ring true! I've also just upgraded to a more revealing, solid TT, so it really is time to try something else. Having had not much experience with other amps I find it hard to say what makes Naim different, I do remember having an Arcam Alpha 7 which I found lacked punch. The marketing / upgrade side is also a bit nauseating. What I do like is its slightly chamber sound, which seems to accentuate rhythm, which works with some music but not others! I currently use 'olive' half width amps, though with after market boards, plus the power amp has been altered by Avondale, like many Naim users, our systems aren't really Naim!
