I just upgraded from a 3300 to the 4802 and I feel it is a major difference. Soundstage is more open, midrange is warmer, and presentation seems more effortless than the 3300. I am also hearing nuances in some CD's that I have never heard before with any previous system I have had, including some seperates. Overall I am very pleased.
