Thank you for all your comments!

I am getting a bit confused with all the different types of amps mentioned here. I know i should be asking these stupid questions in the Amplifier section but for convenience sake, please allow me to post a copy here.

Can anyone help to explain :
- Is pre/pro = AV receiver = surround processor?
- Is integrated amp = pre-amp + power amp?
- How should these amps be connected from source to speaker? Are there many different configurations?
- What is the best setup (assuming money is no object) for both music & HT sharing the same pair of main speakers?
