You post your blind listening test result that show that anything other than source material, speakers and room make any audible difference.  I’ll keep posting examples of where people who were utterly convinced they could tell differences in amps, cables, racks, etc find out that they just can't.
That's funny, I bought a krell amp to replace my adcom amp, I couldn't stand the sound of the krell with my adcom preamp it was so bright, but sounded good with the adcom amp. I replaced the adcom preamp and it sounds great now

In my experience everything changes the sound..  tubes, speaker cables, interconnects, power cords and most certainly a piece of gear.  I didn't note you expressed a sonic deficiency you wanted to change.  You do understand a different amp could very easily mean different speaker cables and interconnects..  and power cords.   The better the resolution of your system the larger the changes in anything will appear.
Musical fidelity is a pretty decent brand but in your case keep your current amp
greywolf  As far as pure stats go, not one spec you cite beats my 30 plus year old Audire amps and preamps.  ERGO:  That would not be the reason to change.  I would certainly presume this amp sounds better than my relics, but I did have some very fine Classe amps and preamps given to me, and they were not as good sounding, not because of any specs, but because of a feeling of the sound being artificially faked to spread out everywhere.    Maybe you should just enjoy the music.
