If someone can tell the difference between #12 and #16 they have dog ears, and will likely not hire me to wire their $100,000+ system.
For the average home theater that will never see more than 200 watts per channel #16 is FINE.
They installed a new electric organ/piano in my wife's church and I did the power wiring. They ran all #16 CL3 speaker wire. Home runs to all speakers. You have to see some of these speakers.
This organ can vibrate the building!
