One day next week, someone in a brown uniform driving a dark brown truck will show up at my door with an Aguilar preamp. Of course, I don't want to pair it with a mediocre power amp. I'm after that slug-in-the-gut punch that I haven't really had in spades since I had a back-breaking Crest 100 years ago. Aside from getting 1000W+, a former roadie told me to get this type of performance the power amp should have a BIIIIGGGG capacitor bank and and a BIIIIGGGG transformer. However, I don't recall seeing these two factors mentioned in the spec's for the power amps I looked at. Plus, like bass head spec's, I guess makers can manipulate power amp spec's to tell whatever story they want, like "Transient Recovery." So, what's a kid to do??? Just go by brand???.....(QSC/Mackie/Stewart/Crest/maybe Crown).
