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?

The only single phase 30amp receptacles are twist lock. If you insist on using a 30amp line you would have to change the male ends of your power chords to twist lock. Total overkill as a 20amp circuit is more than enough or multiple 20amp circuits. They should be on the same phase with dedicated grounds and hospital grade receptacles. 
I talked with my electrician and local code is I cannot use 20a receptacle on 30a breaker so 20a breaker it is. 
Scheduled to come Monday. 
What's with this on the same phase advice, residential electric service only has one phase it's a split single phase.
