You are correct about music sounding better through two speakers.I have had many different kinds over the years,right now I have Polk monitor 10's ,225 watts a side,I have also had Paradign,Pioneer,so many I forget all the brands.
I also have a surround sound system,actually 2 of them,but I only play music on the two.No matter what anybody recommends to you ,you still have to hear them yourself and see if you like the sound.Half the fun is going out to different stereo stores and listening to different speakers.
There are all kinds of price ranges.Pick a price range you want,go out,listen,and then decide.
I am actually going to get 2 speakers to hook up to an old av preamp surround system,a Carver,I have 3 separate power amps for it, and hook my PC into it.That's on my agenda as I sit here.
So I also am looking for speakers. But I will enjoy the hunt.
Good hunting to you..
