If you really love music, then your 2 channel system should be totally stand alone with an HT bypass on your amp (Kinki studios Ex-m1+ is a great one). Then add a totally seperate HT amp and use the HT bypass to let your 2 channel system provice the front 2 channels for movies.
If your priority is movies, then most people just drive their 2 channel sound with their reciever, but it will not be high end.
