, a $499USD A-500 5-channel amp is "rated" at 110wpc but weighs only 29 lbs. The ADA-1000 cost 2x as much but weighs 44lbs!
This reminds me of a story from a snooty British audio mag in the 1980's - an integrated amp was reviewed and viciously panned as being horrible, one area the reviewers focused on was the lack of weight of the unit. The manufacturer then changed the model number slightly, did not change any of the electronics, bolted a brick inside and resubmitted for review. The magazine had nothing but glowing praise for how great the unit was and how the mfg'er had learned and built a better amp!
Needless to say when the truth was revealed the magazine suffered incredibly and disappeared within a year!
