Thank you for your thoughts.I have found a 956 mk2 amp, and brought it home, so I had few months to compare both amps. The preamps were 011 and 877 mk2 xlr,both Burmester.I would like that I have had an Arc preamp to test it with Krell, because this way the synergy of components is probably on Burmester side.However, with my speakers , and with music that I listen, 50's and 60's jazz I have come to this conclusion.Imho Krell Evo 302 is much better amp in terms of bringing the actual feeling of presence of the recording, the performers are actualy in the room, you are not seated in the 3rd or 5th row, they are there, and you feel like the stage is right in front of you. That feeling however comes with a price, if the recording is less than good,you will cetainly hear it, and that can be an issue on longer run. Like I said, I had no chance to try Krell with tube preamp, maybe than the things would be different. On the other side, the Burmester is realy refined amp, no fatigue, and maybe better for listening of music that I have mentioned, everything is there, resolving almost to that last partical but never unpleasant. Certainly not bright, warm in comparasion to the Krell. Finally, an amp should be observed in combination with speakers, and I think that now I can say that anyone who has Sf Guarneri should try them once with the Krell, and than after decide whats best for him. For the present moment I have chosen Burmester,but if I had to say which is better amp per se, and without the context of my personal situation, Krell Evo 302 is a clear winner.
