Hello,Artemus. I have heard these amps when working at Salon 1 Audio.The EV-2000 is going to be more robust and deliver more current,it's a powerhouse of an amp.Be sure that your power lines are up to snuff,it draws considerable current during turn-on. It was capable of driving power-hungry speakers and retaining that CJ sound which is very musical. CJ with muscle. Good luck,Tom
