Jae,
The transition of going from talking about cables to electronics is not as smooth. To answer your questions head on: Price alone is neither indicative of a component's performance (objectively) nor of its sound (subjectively)!
Zieman,
I beg to differ. Take a closer look. Name one component that is at the leading edge of technology in audio that is past my Digital Audio Denmark AX24? Name one component in my room that can be outperformed/outclassed by a component at Best Buy. You are getting into it with someone with advanced degrees not only in Physics but also in Electrical Engineering. I think that I know a thing or two about the state of electronics, both digital and analog circuit design, digital filters, cable transmission and electrical and acoustic prorogation theory. I will gladly submit my credentials up for scrutiny and you should do the same. Before you start questioning my contribution you better make sure you know what kind of tree it is that you are barking at!
