Dedicated power

As others have stated, there is no reason for a 30 amp line. One dedicated 20 amp line with a good multi outlet power conditioning unit like a Furman SPR-20i should suffice. However, before you even go that far, try using an isolation transformer on your current connection. Don't worry about all the "mod videos" telling you that you need to fool with the ground system. That only comes into play for work benches where you could screw up and electrocute yourself. Any non-audiophile/hospital grade unit from a reputable company like Tripp-Lite will do. You just want to verify that you will hear an improvement. If you go cheap and get noticeable results, spending more money for a pricier unit probably won't make enough of a difference to justify the additional cost.

As mentioned above don't go through the trouble with a 30A line - run 3 20 A lines instead, labor will be the most expensive part anyway it'll only take a fraction of time longer running 3 lines compared to one.

Run all three from the same side of your panel.  Unless you have a very long run 12Gauge Romex will be sufficient.

I did a 30a line, only one, and it's great. Don't worry about these people needling you for going big and don't use some flimsy transformer. Good wire, good outlets, good power cables, etc. Worth it.

Headroom loss for 14ga vs 10ga is less than ¼db @ ≈14A / ≈1600W

Music power is a fraction of that. Head banger rock @ 120BPM uses about 2 cycles peak energy of the 3600 power cycles in a minute.

Clean screwed connections, not push terminals, make more difference than doubling the wire gauge.

I'm gonna do 2- 10 gage lines with reasonable hospital grade outlets and be done with it for now. Ill look into the fancy fuses etc after the lines are run. Maybe check out the cable company and try out some cables after I get a better amp although I am very skeptical of power cables and speaker cables to a lesser extent. Not saying I'm right..... just very skeptical.
