Sounds like you are leaning towards dedicated circuits.
@.knownothing , if I have been unable to make clear by now that I have dedicated circuits, I don't suppose that anything further I typed on that subject will clarify it.
@immatthewj I totally empathize. If it can make you feel any better, mine will entail spending a day in a spider-infested crawlspace with 18" clearance under the beams.
Yuk! @devinplombier , my claustrophobia is kicking in just thinking about that. Being buried alive is way up high on my list of ways that I do not want to die. And just reading the word "crawlspace" makes me of John Gacy.
Honestly, before you go to too much trouble you might want to assess the worst load you’re ever likely to plug into your existing 12awg circuits, before you declare them inadequate. In my most humble opinion, unless you’re planning to biamp Apogee Scintillas with a quatuor of Krell KMA-800s you’re probably fine
I am kind of leaning that way. With the three circuits that I have there's a few ways to do it, which include having my amp all by itself. It is a small room, and it is not like I am listening at earth moving dB levels.
Doesn’t this fall under the weakest link category?
@curiousjim , I am inclined to think that it might, but I am not positive about anything anymore.
