I've been searching through the site and haven't found any discussion on the DA7ES. I own the previous Sony 5.1 flagship DA777 and have been very satisfied. I am making the move to 7.1 and considering the new Sony 7ES or the Denon 3803 or moving up in price and going for the Denon 4802. I've noticed that my 5.1 Sony 777ES weighed 54 pounds and was rock solid. The new 7ES tips the scales at only 44 pounds. The 777 had some type of exotic class A push/pull amplifiers. The rest of the line did not feature this type amplification. This may be the reason for the extra weight. I'm most interested in the sound quality. I'm aware that the 4802 will be replaced shortly with the 4803 but do not care to wait until the end of the year. Any recommendations, comments would be appreciated. Stephen W.
