My home cinema setup currently consists of a Yamaha 673 receiver and Q7000 speakers (5.1). It is perfect for watching films, but really disappoints when I listen to music. It sounds OK using the DSP modes to give surround effects to it, but 2.1 stereo just doesn't do it for me. So, what I was thinking of doing was to add another set of proper speakers for music listening, but there are two options here. The receiver has a second room feature, so I could use that and effectively have a pure stereo setup separate from the home cinema one, or I integrate the new speakers into the home cinema and go from 5.1 to 7.1. I'm thinking the former is the best option?
