I'm in the process of totally revamping my rig, and I'm doing it in two steps. Step one is replacing my PLX-2402 and 3402 with one Crest CA9. Step two is replacing my four cabs with one Schroeder 310212. I completed step one this evening and I have to say, I'm absolutely blown away by the difference between my PLX-3402 and the CA9. I ran my PLX-3402 bridged into two 8 Ohm Aguilar GS-212's. That's 1700 watts into each cabinet. Sounded really good, as it always had. Swapped out the PLX and popped the CA9 into the rack and bridged it into the same two cabs. All preamp settings untouched. The difference was eye-popping. My fellow band members couldn't believe the difference. I had so much more volume and headroom. It was simply amazing. I've read several threads here discussing how great these amps are, and trust me, they're true. I remember reading that thread where Jim Bergantino and Bob Lee from QSC went back and forth over matching gains and double-blind tests. I also remember Jim Bergantino basically saying you'd have to be practically deaf not to hear the difference. That's what I experienced tonight. The difference in power, tightness, in-your-face punch was undeniable. I know this can of worms has been opened too many times, and I'm not looking for a debate - I just wanted to report what I experienced. Nope, it wasn't scientific. Don't know if the comparison is fair or not, but my 2000 watt amp kicked the poop out of my 3400 watt amp, hands down. I CAN'T WAIT to take delivery of my 310212 and hear it powered by my CA9.
