Well, I've been messing around with a few amp setups recently, and have had quite a few false starts due to quality problems. Well, I finally have a functioning rig that sounds awesome. I ended up with an Aguilar DB680 into a QSC PLX1602 into an EA CXL-112L. This rig is awesome. There is so much flexibility with this preamp. It is so warm, yet detailed. I love it.
