___ From my experience, position of microphones make huge difference in recording, not to mention whole electronics, like amps, speakers, different type of microphones(loud/silent) and different type of plugs and cables, software, every-bit count there, and it's only little bit of mountain, trust me!
youtube camera records make me smile :) its like colors, you see general picture in black n' white, and now you're imagining how it should look with colors, but you have no clue, nor do I. You should ask how ED recorded 605. I bet they did it like professionals.
