Has anyone bypassed the amp section in the 4802 and ran it with a (more powerful) external amp? I have both the 5803 and the 4802 and have found that with power hungry speakers...these receivers show fatigue at moderate to high volumes (in a large room). I am thinking about using the "pre-amp outs" from thee 4802 and hooking them into an Outlaw 770....and ideas on how this will sound? Does the 4802 have a remote 12v trigger? Any suggestions will be appreciated.
