As for the electronics side of this hobby, having built a very decent amp, I can promise you that you're paying a crazy amount of money for the box they put the stuff inside of. If I bought the transistors in my F5 in bulk and matched them myself, they would have literally cost cents a piece. The caps in the power supply, the trim pots, and the non-inductive resistors in the feedback were about the only parts that cost more than $1. Buying in bulk the way a manufacturer does, they get much cheaper.
Those crazy fancy cases that a lot of companies bolt the circuits into are at least half the cost of the product, probably much more than half in many cases. Do you think a Dan D'agastino amp chassis is cheap to make? It costs more than anything inside of it, I'm certain. Looks sell electronics even more than they do with speakers. At least a speaker might look weird for a functional reason. Electronics just look weird for the sake of looking weird so you'll pay more for it. Personally I'd like a stack of nondescript boxes that just do what they do very well and distract me as little as possible from listening. Spare me the glowing meters and flashing lights. If I want to know what my amp is doing, I'll bust out my thermometer and look. Yep... still hot as a toaster! Resume listening....
