After doing an extensive search and reading a lot of opinions, I felt like I still didn't have an answer.. so, welcome to another "this" vs. "that" thread! I'm using an SWR 550-X through a Goliath Sr., and I'm looking for more headroom and power, simple as that. My rig sounds good if you crank it, but I don't want to have to crank it. I plan on selling the 550-X, but I can't spend very much money on top of that. The two best choices I've come up with are: Carvin B1500: $699 direct, 1250 watts. From what I've read, it's very loud, has a pretty flat response, and is considerably better than the Redline series. I also dig the risk-free trial period. The main "con" seems to be that if something goes wrong, you have to send it to California. QSC 1202/Sansamp RBI: $900 together from Musician's Friend, 1200 watts. The only negative I've read is the mid scoop on the RBI, but I've also read explanations of how to get around that, so I'm not overly concerned. I'm leaning toward the Carvin.. it's $200 less and will take up one less rack space. Anyone wanna help me decide?
