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?

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.
How long are your runs?  Unless they are more than 30' you are just as well running 12 gauge Romex.

If much longer, then run a 60A to a subpanel, and then run short 20A circuits to each outlet.  The advantages of a 60, in addition to lower voltage drop, is that the code may let you get away with not running conduit for it. Check your local ordinances.

Never put more than a 20A breaker on a normal 15/20A outlet, regardless of wiring. It has no audible benefit, and serious safety issues.
