That is a very hard call. The MC252 has all the slam and dynamics of a Krell, but along with the brute power (does it ever run out?) it has finesse, which makes it a very sweet sounding amp. Not as laid back as the MC2102, but close. That being the case, I would opt for the MC252. You'll never experience listening fatigue, and if you did ever decide to let the 803's sing, well then you have that too. The 252 is well above the 803's power rating, but don't let that stop you. The power is so CLEAN, they will be able quite a bit more than what they are rated for. Not knocking the 2102, as it is a remarkable amplifier itself. How can you go wrong with either? You can't.
