I finally decided to pull the trigger and get an amp. I went with the Sherbourn 5/1500a 200w beast! After I got it all hooked up I sat down to listen and it sure didn't sound very deep in the bass department. I then set my speakers to large (i'm running a Yammy Rxv795) and WOW! I can't believe the Studio 100's can take what I was giving them. They truly are great speakers when you give them power. The bass was astonishing, smooth and tight! The amp is utterly silent when running, and after hours of listening it was barely even warm, with no fan running. Movies were unreal. I figured this amp would make the largest difference in music, but my home theater has come alive now. I know there are tons of great amps out there, and this one can be improved on, but I'm assuming you'd have to spend at least $1000 more for me to feel it's worth it. This is most likely THE best VALUE for an amp out there.
