I've been inside all 3 of the amps and plain n simple the DBX is better built, has quality components, wired and soldered extremely well can play and sustain a 1ohm load easily at 1200 watts. I'm pretty sure the BGW and Peavey isn't capable of that ohm load, especially bridged. Yep just looked it up, only good to 2ohm in 2 channel and 4ohm in bridged.
