Designer in wall wiring - worth it?

@zlone about 4 years ago I had an electrician run 3 dedicated lines, one for amps one for digital and one for analog, using standard 14 g wire and Furutech receptacles.  I was able to remove all SMPs's from the audio lines and there is no question of the net benefits.

I moved over a year ago and had the electrician run Audience Hidden Treasure with 4 dedicated lines (one for each amp).  My system sounds better in the new house but it is a different room so who, knows but I sleep better at night.

My electrician being smarter than me ran the 4 lines off a 50 amp box that a Hot Tub was on but not being used because I moved the Hot Tub.  I had calculated the distance from a sub-panel to the target wall behind the gear when I purchased the Hidden Treasure but because the 50 amp box is on the target wall he only used a fraction of the wire I purchased.

I am a hoarder but see no future use and am siting on a lot of wire.  PM me if you are interested in a good deal on new unused Hidden Treasure.

Would you check the cable and post if it is one of these that you have? 

First.

Does it look like this one? Audience In-Wall AC cable .Look at the two photos in the article.)  On the jacket is it labeled CL3? Does the cable have a small bare solid ground wire that is a lot smaller in size than the 3 insulated #10 AWG stranded copper conductors? May be a 16 or 18 gauge solid aluminum wire?

OR

Like this one?

Does it look like this cable?  Hidden Treasure In-Wall AC Power Cable found on the "Cable Company" Website. May look like the one in the Link above.

Does the labeling on the cable jacket say CL2? Does it have a small gauge bare solid aluminum ground wire? May be 16 or 18 gauge? 

OR

Kinda look like this cable. The aluminum clad may be painted.

@jea48 It's the Hidden Treasure, I purchased it bulk from Cable Co.

Thank you.

Do you know if the Electrician used the red #10 conductor for the safety EGC, (Equipment Grounding Conductor), for each dedicated circuit?

If you are not sure would you feel safe checking at least one of the dedicated branch circuits? You can check just one of the wall outlets. Pick the easiest one to get to.Turn off the breaker that feeds the outlet. Verify 100% the outlet is dead. Plug any item into the outlet to verify it is dead.

You will have to remove the outlet cover plate. Then remove the two 6/32 machine screws that hold the duplex receptacle to the wall box. Pull the outlet from the box just enough to look inside the box. You may need a flash light. Is the box steel or plastic?

Look for the red #10 wire/conductor. The electrician more than likely taped it green using green marking tape.

IF the box is made of steel...

You should see the Red wire, (green taped with green marking tape), has two pigtails attracted/connected to it with an insulated wire connector.

One pigtail fastens to the back of the steel box with a green color 10/32 machine screw.

The other green pigtail fastens to the green color equipment grounding screw on the duplex receptacle outlet. (Good chance the green insulated pigtails are #12 AWG copper wire manufactured grounding pigtails.

IF the wall outlet box is plastic, the #10 stranded red, taped green, wire/conductor is fastened directly to the equipment ground screw on the duplex receptacle. If that is the way he did it, he more than likely used a crimp on spade lug. He also could of used a manufactured #12 green grounding pigtail and jointed/connected it to the #10 stranded ground wire. The green pigtail fastens to the duplex outlet green equipment ground screw.

I would have to move my rack to get back to the plugs. 

I also fear electricity more than snakes and spiders so I am hesitant to muck around.  

I would guess the electrician wired it as if it was regular Romex, however that's done.
