Benefit of shielded ac wire? Any downside?

@oldhvymec. Tmi :)

@teo_audio and Miller carbon. I'm speaking of the in wall wiring. Would like to be further informed. I understand? Wire acts as an antenna and thought?  10 gauge shielded wire from the breaker box to the receptacle would be a good idea. Thirsty for knowledge :)

@ mijostyn. Thanks. How/why did you decide on this?

Ptss, a very good timely question as I am building a home and will place 2 dedicated circuit for my system. I am also wondering the benefits of running shielded cables to the outlets from the main breaker box.

I recently moved to a new house. I have wired my system from the breaker panel with starquad 12 awg solid core wire direct to my distribution block. And a 10 awg , counter rotating, earth wire. Starquad has the advantage that it is a selfshielding type of geometry combined with lower inductance due to the double run.  I only use shielding on low level cabling and some digital equipment. Shielding gives blacker backgrounds, more details, but can kill the boogie factor and leads to compressing transients IMO.
