In my current system I prefer listening to music in 2-channel as well. Of course, my opinion might change after I replace my Cambridge Soundworks surrounds with QS4s.
Preference has a lot to do with experience. I've spent most of my life listening to music from 2 speakers, so I expect music to sound a certain way. I have a few surround SACDs, and some do a better job of being transparent in the use of the surrounds than others. The ones that sound best to me (besides DSoTM, of course!) are the ones that use the surrounds sparingly, and solely for ambiance or helping define the space of the recording location.
