Newbie Buying Home Cinema System for Bedroom

[admin_exported]

Hiya, I'm looking to buy a home cinema system to connect to my PC. Here is the system I'm thinking of getting:

Sony BDP-S370

Sony STR-DH800

Jamo A102HCS5

LG 32LH7000

What I'm looking for is a compact system that is good with music and for movies, but I think this might be a bit too powerful for my bedroom and for the speakers. I don't really know much about Home cinema but don't want to get a system that doesn't match up.

Please help

Wondering how big your bedroom is, but also how the PC features in the setup?
