As others have said your speaker/receiver cost allocation is backwards. With all due respect, not just a little bit , but really, really backwards. The receiver has practically nothing to do with what your will hear. Speakers and room acoustics are almost everything. Assuming the 3807 is $1200, take $700 of that and buy a $500 receiver and add that $700 to your speaker budget. That will make a HUGH improvement in the sound you hear.
