Dedicated Line - Things to consider

Thanks @carlsbad for the wire gauge recommendation. 
 

@immatthewj I searched and read a lot of the posts but didn’t see anything comprehensive posted recently. 

@whart  I am planning to use a commercial electrician who had done some work in the house already. Thanks for a detailed write up. I’ll probably end up putting a sub panel. Interesting about crap still present in the line that’s introduced by appliances despite the dedicated line. Thought that’s what we’re mitigating by running a dedicated line.

Distance from panel to the outlet that powers the system is probably over 60ft or so considering walls, bends, etc

So what I gather so far…

10 or 12 gauge wire. Copper bus bar panel/sub panel. Whole house surge protector (definitely a possibility). Multiple lines - I figure 1 for the amp, one for non-digital sources, one for digital. 
Any particular brands for wire, panel/sub panel, surge protector?

Oh and I am using good outlet now that I like so I’ll just get few additional ones depending on how many lines I end up running. 

All…thank you so much! Lots of good points on the dedicated line as well as on the surge protector.

And @immatthewj thanks for posting those links!

@bikeboy52 thanks for the compliments!

@ghdprentice I’m keeping this one simple - no audiophile wires :) just good quality copper is all I think I will need. 
 

I’m leaning towards 2 lines. That will allow me to connect monoblocks if I ever go that route, and keep the source separated from the amp(s). Will figure it out in the next month or so. Putting it all together into my plans for early 2023.

That’s exactly what I’m hoping for - lower noise floor. And that is a huge improvement if that’s what the outcome will be.

@immatthewj please let us know what you’ve heard as a result of the test when you get around to it

Will post updates. Planning do it in January/February. 

@immatthewj thank you for taking the time to post the results of your comparison. I’m pretty much set on running 2 lines. I think that’s all I will ever need. Plenty of flexibility with that. 

Two dedicated lines are in! Breaking in.

Thanks to everyone who contributed and provided a sea of great info.
