Dedicated Line - Things to consider

Hey all,

So…as far as building my system is concerned, I’m pretty much in a good spot for now with the components and cables. I can say I’m satisfied with the sound. But, as we all know, system building isn’t an action that can ever be completed, it’s a state we’re constantly in.

Right now I have few finishing touches left. 
1. Run a dedicated line 
2. Improve room acoustics

Wanted to solicit some thoughts on running a dedicated line. 
First of all, is it a worthy addition? What are the deciding factors? I realize all the appliances in the house 💩 into the power line, and I use a power conditioner for the source components. Amp is plugged directly into the wall. 
Here’s what I have in mind if I’m to go ahead and run a dedicated line - 14 awg solid copper wiring - any particular brand? 20A or 15A circuit? Is it worth running one for the amp and one for source components? Or is using one duplex outlet on a dedicated line sufficient to cover amp and source components? 

Would appreciate any thoughts based on experience and lessons learned…what would you do differently if you were to do it again? What improvements should I be expecting?

Thanks in advance for sharing your thoughts!
