I am setting up a 5.1 system. I just picked up an outlaw audio 755 amp to drive a polk setup consisting of 2 two Lsi 25's fronts and two Lsi 15's rears with a Lsic center channel. I had been driving them with a Harman Kardon AVR7200 which never really sounded all that great. I now understand that these are some very demanding speakers and love lots of power, more than the hk was able to give them. Now I am needing the final piece of the puzzle. What type of head unit to drive the amp. This setup is used for watching movies and TV mostly, while still being able to enjoy concerts in high def with the sound turned up. Any input would be greatly appreciated. Was looking at the new onkyo 40.1 but seems like a lot of money for what I need. But if that is the best way then that is the way I will go. At this point I am a little lost. Thank you in advance. One last question, If i went with a powered receiver would I be able to use the outlaw amp to drive the 5 speakers and use the receivers power to drive two small speakers up front to take advantage of Dolby ProLogic IIz with its front height speaker capability.
