The audio shop is driving the speakers with a Yamaha RX-V861, and this is the only amp i have demoed. The fact is, I have been spending most of my time choosing speakers (neglecting amps & players) because I think getting a good pair of main speakers would increase my immunity against the upgrade bugs

I plan to spend around $4k for a 5.1 system. If I get all the equipments as below i would be 10% over budget.

Sonus Faber Concertino Domus
Sonus Faber Center Domus
Velodyne VX-10 subwoofer
Wharfedale Rear Diamond 9 DFS
Yamaha RX-V861 AV Amplifier
Pioneer DV600 DVD Player

If this is going to save me some bucks in long run i don't mind spending the extra 10%. I can always upgrade the 2-channel music quality later on by adding a good stereo amp / pre-amp and a CD player as budget allows. This is of course based on the assumption that there is no single good amp for both music and movies, hence I still need the RX-V861 for 5.1 movies.

I am still wondering if a bookshelf is sufficient for my room size (17x17 with one side fully open). Any idea?

For now, I have not committed to anything yet so my options are open.

Any comments on the equipment list above? Any other suggestions on how to spend $4k?
