Vintage UREI 1620 Output Transformers installed in the mixer, and it sounds best with both the ADM EQ and (modified) Bozak Isolator. The combined effect of the signal processing with the inherently "compressorish" character of the mixer at high outputs means that I can play bigger rooms without subwoofers.
This rig sounds great through my Klipsch Heresy Industrial speakers powered by a homebrew 60WPC tube amp. Kind of like bringing a vintage hi-fi to a bar and playing through it.
I think the rig needs a few more giant silver knobs though...
