What do you think of this setup?

I'm about to purchase a home theatre system and I thought I should run it by some AV experts to see what they thought first.

I'm looking for a fairly good system that I will use mostly for surround sound and occasional as a stereo system (for parties). For the stereo use, I want to make sure the system is quite loud, has good bass, and has very minimal distortion at high volumes. I'm looking to spend ~1200 bucks. So far based on my research, it looks like this may be a good system for what I'm looking for.

Harman Kardon AVR645 receiver
Infinity TSS-1100 speakers.

Do you think these speakers will complement this amp very well? If not, any other system recommendations in my price range. Thanks in advance for any opinions.

Thanks for your input.

What about the Infinity Primus Theater Pack and a SVS sub? Looks like the sub will kick but, however, what about these speakers? I read some good reviews, but will the HK 645 have too much power for them? Should I look into the HK 445?
