I was in your same dilemma a few years ago with a really good HT set up Yamaha 3080 with 9.2 polk lsim series speakers that also did music, or so I thought. I bought a Peachtree Nova 500 2ch integrated which is by no means super hi-end. But the stereo dedicated integrated upped my 2ch sound quality 100 fold I couldn't believe it even with the polk 707s. I've since scored a mint set of B&W N803s and the music just keeps getting better. What I learned is if you want sublime 2ch you have to pay and build for it, HT AVR will never cut it, it's just not made too. Although you could "settle" for good enough......
