Sound guy,
After 18 years of listening to high end systems, I think I'll stick to what is the culmination of Jim Thiel's illustrious and well-documented career. The CS3.7's (they beat the 7.2's and I KNOW this from experience) are perfect for my room and my taste. I've listened to a large number of their closest competitors. To improve upon what I like about speakers, I'd have to reach well into the $20k plus stratosphere and it was hard enough for me to afford the 3.7's used. And, BTW, I never called it an upgrade "bug." It's a mere itch. lol. That said, I,too, am skeptical about the resulting "bang" from upgrading the amp, ergo the thread. If someone would bring over a pair of decent monoblocs to my house, I could sort this out in a jiffy. ;-)
