Aven,
I'm in the same boat but from a different perspective. I already have a 5.1 system. Not being able to have two separate systems I want to build upon my current rig for 2 channel performance. My first step was dealing with my source and I think you should do the same.
Adding a 2 channel pre-amp or as Artizen65 suggested an intergrated with HT bypass will increase your music playback. A couple of intergrated's with HT bypass Plinius 9100,Krell 300xi, Sim Audio Moon I-3. I'm sure there are more but those are off the top of my head. All this would work if you sony reciever has pre-outs.
Well good luck and keep us posted on your journey.
