tweaking audio systems with modifications.

it was a long time ago that i was here on this site...talking to you guys.

so how do you tweak your audio system?? is it possible for a low cost?

basically like maghister...guy seems like a genius since he says the sound quality is really good. but he made all this stuff himself. i want a cheap system...but it must sound really good.

i want to build a system one day. but i don't have money right now because i am not working. my wife refuses to buy me a system.
