Late Saturday night I went ahead and got the update for the 3808 and lo and behold the sound difference was quite noticeable. While I have enjoyed the 3808 I always felt that while it was a great functioning receiver that it didn't quite have the gusto that I was looking for. Even after adding outboard amps it sounded good but not quite great. The Dynamic EQ system seems to have filled in whatever was missing before with the regular Audyssey.
A-ha!!, I am not crazy, I am not the only one who felt that Audyssey was lacking until this update. I have spent a couple of hours playing different songs and turning the EQ off and on and going to flat mode and the EQ setting is a marked improvement.
