I think I would throw a v3 behind them, or maybe even a mini-me! The mp2->modsbm is very dark, a nd quite frankly, wayyyy too dark for my ears. The only reason it sounds good with mbho's is because they are so freakin bright as it is!
Daryan, this surprises me a lot. The MP-2 > modSBM sounds almost exactly like the MiniMe with the Gefells. The MiniMe has greater high-end frequency extension and tighter bass, but the tonal characteristics are spot-on. FWIW, I ran the MP-2 > modSBM and I loved the combination; it produced some world class tapes with the Gefells. Then again, I like dark-sounding tapes so this may have something to do with it.
As for the 480s, I agree with some of the other opinions mentioned. I like them with a m148 > Apogee A/D or with a PS-2 > modSBM-1. You can't go wrong with either and there is an option for every budget class.
