Dedicated power

In many jurisdictions, a 30A line will require a receptacle rated at 30A, and that won't be compatible with the 15A or 20A plug you'll find on your component. In any event, I'm not aware of any amplifier that requires a 30A line.

Hmm ill check into local codes on the 30a line.. 

I basically just want to be ready for anything I get. Parasound hca 3500 or Musical Fidelity kw500 I hear it is reccomended 30a and I am looking at both of those. 
Running a temporary amp Aragon 2002 at the moment with Pioneer S-1ex speakers. I'm not totally convinced its a power issue but rather a room overload issue at 90-100 db which i don't listen to all that often. We shall see. 

It's not. No one needs 30A. What does help though is the larger gauge. But not enough to be worth the $$.  

I've actually done this stuff mofojo and not just once but three times, or four or five depending what you want to count, and all in the same room, so know first hand exactly what does what and how much and the cost and trouble and all of that. More than you know. https://systems.audiogon.com/systems/8367 

Do not run 2 lines. Just don't. It is a really stupid idea. According to Michael Fremer https://ultimist.com/video/2018/07/21/michael-fremers-listening-room/ Skip to 15:50 I posted almost this exact same thing within the last week but apparently no one knows how to use a search bar. Don't take it personal- no one does!  

The biggest most cost-effective is to just run one 20A line direct to your system, put a Synergistic Research Orange outlet in there, and call it good. Because next up from that is a larger gauge wire, and it will sound better, mine is 4ga, but for the cost you get more improvement from one $160 Orange Fuse. Next up from that is to cryo all the wire, but even if you find the local deal of the century like I did and schmooze the guy into doing your wire for fifty cents a pound, it is a nice improvement but again not worth the expense and hassle compared to a Orange Fuse. 

Next up from that is change the 220V circuit to 240V and use a step-down transformer, and here the quality of the transformer is everything. I got a great deal on a used Audio Consulting and would never go back but that is an all silver wired 40 lb transformer would not want to see what they go for now. Get a good power cord, same improvement, whole lot easier. 

Why you are probably wondering have I done all this stuff that is not worth doing? Good question. This was THIRTY YEARS AGO there was no one to tell me what was what. More to the point the things like Orange Fuses that are now more cost-effective did not even exist back then. 

Learn from experience. Run your ONE line. Spend the rest of your money on Schumann generators, Townshend Pods, SR HFT, ECT, PHT, and other stuff that is far more bang for the buck and way less time and trouble than running AC lines.

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.
