I agree that it is a waste to use incredibly expensive in-wall cable to connect to the public mains. On the other hand, I think there could be a benefit if one also installs a power regeneration device ahead of the in-wall cabling at the breaker panel.
I think one would get more cost effective benefit from using Romex for the dedicated line and putting the savings toward a power regeneration device - then use very good PCs. In the long run this is more flexible in that the regeneration device can be relocated with the playback equipment or it can be resold if desired. 6 nines OFC 10/2 is going to stay in the wall.
