He used 12 ga. armored cable, run outside the garage wall, which backs up to my room. It's only a short run from the breaker to my listening room, perhaps ten feet. Here is my concern. Instead of using one continuous run of wire, he made two splices inside junction boxes he added. He said this was to follow code.

>>>>>>>>>>>>>>>>>>>>>>>>>>

Rule number one, ask questions before the work is started. Have the electrician walk you though the project and explain how he will be doing the wiring job.

Not being able to see the job I can only guess how he wired the branch circuit. By your description of the project he used MC cable. He had to get out of the panel, and I assume the panel is recessed flush in a finished wall. There is one box, one set of joints. He installed the box for appearance. Second box, again for appearance he set the box and exited the back to feed the receptacle rough-in box. Another set of joints here.
Sound about right?

Several things he could of done different to eliminate the joints.
(1) Installed EMT conduit exposed on the wall of the garage still setting the two boxes for appearance. EMT would of looked a hell of a lot better on the wall than MC cable. At the feed end from the panel to the first box he could of used (GF), Greenfield, flexible metal conduit. The same at the other end run of the EMT and box, for the receptacle box feed. He then would have had an empty raceway to pull the solid conductor branch circuit in continuous with out any joints.

(2) He even could of done it with the MC with a little more work. It would of required still using GF from the panel to the first box and from the second box to the recept box. On each end of the MC he would remove enough of the metal armor from the wire, for the wire to extend through the GF and for make-up.

There are other methods as well......

As for where you are now:
10ft #12 awg solid wire, plenty big.
If the joints were twisted before the electrician installed the wire nuts again fine. Providing he used a compression type wire connector like "Scotchlok" brand or equal.
