Dedicated power


I'm looking to run a dedicated 30a and dedicated 20a line to my system directly from the fuse box. 
I currently have some florescent lights and some other junk on the line so I'm hoping it will be an improvement. Things sounds like they are straining somewhat when you crank things up. The amp will go on the 30a line and the digital stuff on the 20a. 
Anyone done this and saw improvements?

Do a search on line for this article by Vince Galbo: How to Wire Your House for Good Power -MLB Technology. It has all the answers and explanations you are looking for. It’s very good. 
I'm a balanced power fan. Equi=Tech, Torus, Balanced Power Technologies(out of business but buy used and they last forever).

Gigawatt brand circuit breaker....are they available in US, or what is similar?

Hmm maybe I will stock with single line. I guess other issue with 2 is it's a real bear to run these. I am in basement and where the fuse box is there is no basement under it (concrete). We figured out a way to run it but it is tight and the 2 lines would need to be close together for most of the run, maybe inducing noise?
 I'll ask my electrician what the local code is about the outlet. If I can use a 20a outlet on a 30a line I will do that. If not I will stick with 20a.
