Seems like a nice, balanced system. Excellent work. Now, IMO, because you've done such a nice job of building a balanced system at this price point,
to really upgrade, you'll want to plan a *round* of upgrades. What I mean --
You'll want to upgrade your speakers, but to get the most out of better speakers, you'll want to lose the receiver and buy a separate Amp and pre-amp. Personally, I would stick with two channel and focus my expenditures
there rather than get into multi -- but that's me. I set up a multi-channel system with really nice stuff all around. I'm back to two channel for good --
even with movies and High Rez digital music. If I were you and I was in college, I think I would enjoy this system. When you start your upgrade path,
I would start with speakers.
