AVR and 2.0 speakers for music, 320-380GBP

Hello, I'm looking for a new sound setup for our bedroom. It'll be connected to LG 32LH3000 and WD TV Live HD.

Use: mostly music in 320kbps and FLAC(rock, pop, dance), internet radios and TV shows, sometimes games via X360

Price should be 10000 - 12000CZK (320-380GBP)

I guess Q Acoustics 2020 will be fine (about 170GBP here), but I'm not sure about AVR.

I know I can't want superior sound in this budget, but everthing will be better than TV speakers.

Do you have any ideas or tips? Thanks!
