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?

You may add additional ground rods to the original circuit however.

Please correct me if I'm wrong, but I believe this is what I have done, the two isolated ground outlets have a shared ground rod which is an additional ground point in the system.

It can't be additional, unless it's physically tied to the existing grounding rod(s).

The one answer I can't seem to find anywhere is on a sub panel in an out building that the neutral is isolated from the equipment ground with a grounding rod, are you supposed to bond that ground rod to the service entrance ground rod.

I believe a sub-panel is required to have it's own grounding rod. One of the more knowledgeable guys will be along, hopefully, to confirm or not.

Thanks builder3, I am likely in NEC violation! I do wonder the potential hazard of my set up...and wondering if there will be a sonic advantage/disadvantage to correcting my set up by linking the outlets' ground to the incoming service ground rod. I'm also wondering if grounding to the handy box/conduit is a sufficient ground link. Many thanks.
