Dedicated power

Well its a minimal expense running the second line and I figured having the digital and amps separated would be a good idea. I will read your link you posted. Will look into the orange fuse as well. As far as cryo wire and transformers prob not ready to go that far yet! 
For 400 bucks all in I figure it very well could be a very reasonable improvement. 

Two weeks ago I added two 20 amp lines. They go directly to the outside box. The sound has become a little bright with everything plugged into the new lines.

Maybe you're interpreting a 30 amp line with cable for a 30 amp line? Running a 10 gauge is for 30 amps but you need a 20 amp receptacle on it. 

There's no need for a 30A circuit. Listen to @cleeds .

Two 20A breakers, 20A hospital grade or audiophile duplexes, and 10/2 or 12/2 Romex. The lines from the service panel should be run with 12" separation from each other.
It's important to wire the lines to the same (leg) phase in the panel. Any high-current-draw appliances such as refrigerator or air conditioner should be moved to the opposite leg.

Put a Cruze First outlet in and call it good. I have owned both and the Cruze sounds better to me and is much cheaper. Also check with the manufacturer of your components to make certain the Synergistic fuse or other exotic fuses wont void your warranty. Due diligence is required when using some of this exotic stuff like fuses. Hearsay from one manufacturer states that the S.R. fuse is more interested in protecting itself than your equipment and other manufacturers provide blanket warnings regarding exotic fuses.
