Re: BUILT IN ROOM CORRECTION
The first receiver I got with auto room calibration was some Sony model. It did a great room eq, but the switches and receiver components were junk. The next receiver I got was the Onkyo 674 which without question blew the Sony away. I was astounded at the performance quality of the room correction. And the receiver still let me make my own tweaks to personalize the sound of my room. Having tuned rooms by hand, I found this receiver automated correction to do a marvelous job for how quick and dirty it performed the tests.
