Designer in wall wiring - worth it?

@zlone excellent. Should reveal difference in wiring if any. My only reservation would be that it may change the sound signature of your system and there’s a potential for a domino effect with other cables and even components. 

@invalid, I believe you are correct! I stand corrected!

I found this info on the "Cable Company" Website.

It appears it is Listed as in wall branch circuit wiring.

In the description:

Hidden Treasure features three 10 AWG stranded copper conductors, insulated in polyethylene and can be used for either 120V or 240V.

.

In the Specifications it says, "Ground: Annealed bare copper".

I can’t see the bare ground wire in the picture. It must be there though, along with a drain wire for the shield.

I once tried Kimber, my house wiring shut down because of it, I swear these people live in a dream world.

Solid core is always what should be used as it does not overheat and limit the gauge to that which your breaker reflects as maximum current for the line.

I know I do sound rather sorry and apologise for not knowing the product you refer to, but after my Kimber incident, to me it's like putting Balls in a fat fryer

Good example for not using a cable that is not designed, manufactured, or Listed for use as AC mains power wiring. I remember reading a posted message on another audio forum where a member built a power cord using multiple paralleled runs CAT 5 Ethernet cable. 

.

FYI,

Solid and stranded wire have the same Ampacity rating.

NEC Table 310.16 Ampacities of Insulated Conductors With Not More than Three Conductors Current-Carrying Conductors in Raceway, Cable, or Earth (Direct Buried)

Yes, Romex, (NM-B sheath cable), Sizes, 14, 12, and 10AWG conductors are solid wire. But, #8AWG and larger are stranded wire conductors.

MC (Metal Clad) cable is made in both solid and stranded wire. #8AWG and larger are stranded wire only.

Individual insulated conductor #14, #12, #10AWG building electrical wire in manufactured in both solid and stranded wire. #8AWG and larger is stranded only.

Sorry guys, I still have a problem with the Hidden Treasure In-Wall AC Power Cable - Bulk,  by Audience  

This is the info printed on the jacket on the cable shown in the picture.

  E256938 Type CL2 (UL) FT4 75C 10 AWG  ( Website,  "Description" says its CL3 (UL) Listed.)

Yes the cable is Listed (UL) as a CL2 (Class 2) cable. But a CL2 cable is not Listed for use as mains power circuit wiring. In wall or not. (Or a CL3 UL Listed for use as in wall power wiring)

CL2 and CL3 circuits falls under NEC Article 725.

Explaining NEC Article 725 on Power-Limited and Remote-Control Circuits  

Class 2 and Class 3 Power-Limited and Remote-Control Circuits

• Class 2 Circuits:
  • Class 2 circuits operate at up to 30 volts and a power limit of 100 VA. Their goal is to protect from electric shock.
  • Typical applications include thermostats, intercoms, automated lighting, and control circuits where power demands are minimal.
  • Due to their low power and voltage levels, these circuits pose minimal risk for shock or fire hazards, so NEC permits more relaxed installation methods, like running cables directly along structural elements without the need for extensive conduit protection.
  • .
• Class 3 Circuits:
  • Class 3 circuits share similarities with Class 2 but allow slightly higher voltage and current levels. Class 3 circuits are allowed to operate up to 150 volts. They are used in more demanding control applications like HVAC or specific industrial settings.
  • These circuits require more robust insulation and need additional containment if installed in high-traffic or mechanically vulnerable locations (public corridors, rooms with industrial equipment, etc). In these cases, metal conduits, raceways, or cable trays can be used.

Note this:

• Grounding:

• Unlike higher-power circuits, Class 2 and Class 3 circuits do not require a dedicated grounding conductor due to lower voltage.

Audience In-Wall AC cable. Look at the two pictures shown  in the article. The first one only shows a shielding drain wire. Not an EGC, (Equipment Grounding Conductor) wire.

The second picture you can clearly see the cable jacket says CL3  (rated ???).

Sorry guys, I am back to saying the Audience hidden treasure in wall cable is not interned for use as power in wall branch circuit wiring to feed audio equipment. 

I would suggest checking with the AHJ (Authority Having Jurisdiction) Electrical Inspection Department in your area before buying. 

I will add one thing about the fine stranded #10 wire used in the cable. It could be a burger to terminate on the breaker in the electrical panel and the receptacle outlet you are using. As for the receptacle, use one that has the back wire feature that uses a terminal plate to mechanically clamp down on the wire when tightening the side terminal screw.

As for the breaker termination? Depends on the type of lug used on the breaker. ??? Getting all the fine strands securely supported in the terminal connection of the breaker could be a challenge. Loose stands, just makes the wire gauge smaller. 

Finally you might ask is it electrically safe to still use the cable as in wall branch circuit wiring to feed your audio equipment? Question back, Would you feel safe using a 10/3 PVC jacketed flexible power cord as a dedicated branch circuit wiring from the electrical panel to the wall outlet. After all, the flexible 10/3awg power cord is UL Listed for power. Yes it it Listed for use as a power cord, but, not for installing in a wall for branch circuit power wiring.
