High quality in-wall UL-C2 rated 10-gauge A/C wiring ?

I am looking to re-wire my listening area front-wall with a dedicated A/C circuit using 10-gauge UL-C2 rated in-wall wiring. I know Audience makes a high-quality one however I didn’t want to pay $26/foot.

If you are wiring a dedicated circuit for your audio sytem, THIS is the wire to use. Audience In-Wall wire is UL rated for in wall use, and is simply the purist, best sounding wire you could use to power your audio system. Robert Harley, and the Head Geek both use it in our listening rooms.

You have 3, 10 AWG high purity stranded copper conductors for the hot, neutral and ground legs. There is an additional drain wire for the shield, and the outer metal jacket offers additional protection from screws, nails, and RFI. Not only does this wiring sound good, it’s safe. The cable is also cryogenically treated to further reduce self-noise by decreasing the physical boundaries between the crystalline structure of the copper.

Features of Hidden Treasure include:

• UL CL2 approved for 120v and 220v AC in wall applications
• 10 AWG, 3 conductors
• Stranded 99.9999% pure OFC, cryogenically treated copper conductors
• XLPE dielectric with PVC sleeve
• Foil shielded
• Flexible
• 18mm OD

CL2: This is a cable jacket fire resistance rating defined in Article 725 of the National Electric Code. It stands for "Class 2 Remote-Control, Signaling, and Power-Limited Circuits" cable, which indicates that the cable is suitable for in-wall installation and use for certain low-voltage applications. Examples of Class 2 circuits include burglar alarm cabling, intercom wiring, and speaker wire. The jacket is designed to protect against voltage surges of up to 150 volts.
