I'm starting to upgrade with the mains already:
Mains: Boston Acoustics VR-M50
Center: Onkyo (came with mini-shelf system)
Rears: Onkyo (see center)
Sub: None yet
Upgrade to:
Center: Boston Acoustics VR-MC
Rears: Boston Acoustics VRi650 in-wall
Sub: Still undecided
I really enjoy listening to 2-channel music on my M50s. To me they were the best bookshelf at this price point that I demoed, which were many.
