why don't I like it??

My setup right now is Aragon 2004 mkII, Klipsch kg3.5's, and a yamaha rxv-659. My old roommate had an Adcom gfa-5400 and I loved it. When we separated, I wanted another amp. I did my research and decided on the Aragon. I know the Aragons have a great rep, but I'm just not impressed. I've owned it now for several years and it's never quite grown on me. I love it for ht though, which is the reason why I still own it. Being married with kids changes how you use your system--ie., can't jam out to music all the time!! I think the problem might stem from the kind of music I like--rock. The crunched guitars sounded so much better with the Adcom. It might be the Aragon is too "clean". While in a different room set up, I swear the Adcom had much better detail and imaging I've had the Aragon in two different room setups and nothing really changed. What do you think?
