When you say, "Some of the amps in the LA area" of which amps are you speaking? Different retailers obviously carry different brands.
Additionally, the LA area is quite large, as I'm sure you know. Do you mean the West side, the Valley, Downtown, Ventura, Orange County, the Inland Empire, or somewhere else?
I don't mean to be a pain here, but I want to offer whatever little bit of advice that I can, tailored to what you really need.
