Test a new dedicated circuit before installing it.

So, I may take the plunge and run a 10/2 romex to my system. I'm slowly building/rebuilding my (midfi, gravitating higher) set up and sort of going backwards with first buying cables, conditioners, etc before the big components such as integrated amp or preamp.
Anyway, before installing in the wall, I wonder if I could just hook up the romex into my panel and do a quick connect since its only a 25 ft long cable I will be using anyway. I just purchased those little noise detection tools which may help see if there is any difference. I'm just trying to avoid running a circuit in the wall in a box if it ultimately won't help.

Currently I have a dedicated 20 amp 12/2 but there is more than one receptacle on it but the others are just not used. The only thing used on it is my AV setup.

Worth it?

The only benefit of 10/2 vs. 12/2 is lower voltage drop, which increases with current.

You are unlikely to notice this unless you have a long run. Certainly it won't reduce your noise.

I have about 6 receptacles on the current circuit, but only the AV system is using it. Using 2 of the receptacles. They are daisychained like MC mentioned. I guess connecting the wires together and pigtailed off them onto the receptacle would be better than going through the receptacles to finish the circuit.

The intention was to install one receptacle and plug in 2 x Niagara 1200 units to that receptacle.  Then, everything would plug into them.

I'm lazy enough to just leave it as is and just plug what I have now,  then plug  into the 2 Niagaras.

I already ordered the tester, so I'm sure I'll Tinker with it.

Thanks for the replies. 

My panel is < ten feet away from my system and I have some access to the area. But again, lazy...

I've tested my voltage over the course of a day and it was 123v constant. No fluctuation at all. 

So, if I pigtailed to a SB receptacle would it still be beneficial using that existing circuit and coupled with the Niagara 1200's? The noise floor, to my untrained ears is pretty low, but I do hear a slight hiss from 10 inches away from the tweeters. 

I'm trying to do the "can't really hurt" little things while waiting to upgrade other components.
