Zone 1 is your basic 5.1 or 7.1 setup.
Zone 2/3 is additional setups
For your need, your bedroom where you need the HT setup, we call it zone 1. The living room where you want the music setup is zone 2.
So what we mean here is, you can get a Zone 2 capable receiver like Onkyo 606: (
Onkyo TX-SR606 - 7.1-Channel Home Theater Receiver | Model Information | Onkyo USA Home Theater Products ).
Using this receiver you can setup a 7.1 in your bedroom. Then connect the zone 2 output from the receiver to you 2.0 music speaker setup in your living room. You can infact operate both at the same time, as in your wifey can be watching her movie and you can shut the door and listen to music in your living
. Onkyo 606 comes with powered zone 2 so you dont need a seperate amplifier for the zone 2. But a seperate amp will make a lot of difference in SQ.
This is the typical setup for you. But, if you need a SQ setup, then you need to invest in two separate systems
bcos all AVRs are not great in music handling. They are usually tuned more for movies.
If you are not too much a movie guys, my suggestion:
1. Get a Philips 4750 for 20k for you bedroom
2. Get a good 2 channel amp (NAD, CA, Cambridge etc), good a CDP, and a good floor standing speakers
