Designer in wall wiring - worth it?

Speak to a Professional in Electrical Code, there will be good guidance about the legality and if it is covered in an insurance claim, is needed to be made on the home insurance policy. 

A step-around option might be discovered that meets code if the proposed method is a breach.

Alternatively, have a look at a standalone power supply from a battery bank and an inverter.

What wiring is currently in the wall? if it’s the 10awg or 12awg solid core copper romex you should be ok. 
Also, if you don’t yet have good outlets, look into it. 

I used 10 gauge romex. I was aware there was high end wire for direct lines... but didn't go that far. If someone has, I'd be interesting how it compared before. I would guess that it was better. But no experience on my part. 

No Professional Guidance? - No Code to be advised on?

Mathew 15.14 Thank You for your wisdom.

Any special wire from the breaker box to the outlets? Yes: For dedicated audio lines I would go with Type MC Galvanized Steel Metal Clad Cable 10 AWG with solid copper core conductors and insulated ground. It has better EMI and EF shielding versus aluminum armor or NM cable. 😎

Has anyone tried the Audience cable or other "designer" AC cabling? 

No!
