I've read a couple of reviews on the Bass Gear Review archives that the QSC PLX series of Power Amps is a little light on the reproduction of the higher frequencies, but that it can easily handle tons of lows. My current amp is a Stewart World 2.1. I'm thinking about selling the Stew and getting a PLX 3402, but one review I read stated specifically that the QSC didn't reproduce the highs as well as the Stewart. can anyone out there support these comments? I'd have to sell the Stew, get the QSC and find that I've goofed.
