Well, it finally arrived! I finally replaced my Sony STR-DE475 with a Sony STR-DA2ES. WOW, What a difference! I could not believe my ears. First, I calibrated my speakers using my Avia disc and RS SPL meter. Then I put in the pod race scene. My bass was cleaned up substantially. I had to turn it down 3db! Next I played the intro to Jackass the movie, the cannons were great! (I have another thread somewhere around here talking about the audio dropout from the de475 during this scene). I finally calmed down and watched a movie I rented (Stealing Harvard), I noticed the center channel sounded hollow, but i'll play a couple more movies before I start tweaking the EQ. This was money well spent IMO. Now I have to find a rear center speaker that matches my setup (I have an old 50w surround back there now). Anyone got an extra Energy Take speaker laying around? Please feel free to share any similar experiences from your receiver upgrades.
