Don't get hung up on the ratings game that is not part of the HiFi world. You are listening for sound quality not looking at numbers on the sales brochure. If you must look at numbers look at what it weighs per amp channel after looking specs up looks like yours weighs 3 pounds a channel. The Hagel that was recommended above weights over twenty pounds per channel. Which do you think have a better power supply? Bigger transformer in in? My amp is rated lower than yours and weighs over two hundred pounds a channel. How low of ohms can your speaker go and your amp still be stable? Years ago the appogee duetta signature was one of the best speakers in the world and they changed the amplifier construction they went down to a half an ohm or less and many amps just blew up trying to drive an almost dead short. Might be an idea for you to visit some truely high end stores and listen to some demos. Go listen to a half million dollar home theater system and you will understand that numbers are just about meaningless sales brochure stuff.
