[QUOTE="Orcish75, post: 1055557, member: 21448"] Spot on! Current delivery by an amp is the most important aspect of an amp seeing as speakers are current driven devices. I don't go for the absolute power ratings eg 150W, as it really doesn't tell you the whole story. My Rotel RB-985 is a 5 channel amp, rated to 100W/channel, all channels driven. My Harman Kardon Citation 7.1 is a 4 channel amp, rated at 120W/channel, all channels driven. The torroid in the Harman Kardon is probably two and a half times the size of the Rotel's and the smoothing caps also MUCH bigger than the Rotel's. The HK has been able to drive any load I've thrown at it with ease, even 4 ohm 15" car subwoofers at stupidly loud levels. The Rotel trips into protection mode driving the subwoofers at reasonably loud levels. The Rotel and HK are similarly rated on paper, but the HK can deliver much more current than the Rotel and keeps it's composure at silly listening levels. [/QUOTE]
