From my experience with the DSP3100 vs the EP350, get the EP350 and I have only heard the PB12nsd which IMO is a little stronger performer than the EP350 so extrapolating a ton here, I would say the 350 will be slightly better than the 10-nsd(have never heard the 10-nsd). To me the best money spent for you right now would be on the EP350.
