"Will keep buying these amps"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I have been a sound engineer for over 20 years. I have always ran Peavey amps. However; due to the terrible issues plaguing Peaveys' new IPR series; I have had to look at other brands. CROWN has a good name, but your paying a premium for that name. So that really only leaves QSC. I have ran a few RMX's in the past and never had a problem with them. Though being skeptical about the new digital architecture, i decide to give the GXD a try. It was the right choice, These amps produce a ton of clean wattage and draw very little in return. Overall the sound quality is not on par with the A/B amps, but only an audiophile would hear the difference at higher volume levels. I have one of these powering a set of CVI-218's and another powering a set of DJS-4's. They will get loud and stay there. As always zZounds has been great to work with and I will continue to buy my gear from them/
