Help with DIY dedicated circuit

I am wanting to install a dedicated circuit for my amp, but getting from my panel to the wall behind my amp is going to be difficult. As I was investigating in my attic, I realized that when I changed my stove from electric to gas, the unused 30 amp Romex 10/3 wire will reach within 15 feet of where I want the wall outlet. Do I install a junction box and run Romex 10/2 to the new wall outlet and use the 30 amp breaker? What is the best way to connect the wires in the junction box?

Apology accepted.

Just a guess the last NEC code addition book you were using before you retired was the 1999. The NEC really started changing and adding things in the 2005 edition. Even more changes in 2008, 2011, 2014, and 2017. Probably the most changes in 2008 and 2014.

Done! 20 amp breaker. I went with Romex 10/2 from junction box to a single Porter Port outlet which was a little frustrating manipulating the 10 gauge solid copper connections. I decided against 2 outlets at this time since all my gear is connected to a PS Audio P10 Power Plant. Now, to see if I can hear a sound difference.

Nice thread -Jon,
I look forward in reading more about your aural impressions, thoughts, post-installation of 20A breaker and Porter Port outlet.

Happy Listening!

A definite, noticeable, small incremental improvement with the dedicated circuit. I was skeptical because I thought the PS Audio P10 should be able to produce near perfect power from what comes through most any wall outlet. Voices and instruments float a little more distinctly into position and sound-stage is a little deeper. I was already very happy with the sound of my system, so I never expect big changes with these tweaks. I do think it was worth the effort.
