Thanks to all for the responses. I appreciate the varied perspectives.
@buellrider97 I have a dedicated 10AWG 3-wire 20-amp line, with a Cardas outlet for one 100A speaker (which was originally setup to power the 2-channel Benchmark AHB2), and am running the other 100A off the house 15A circuit (which also powers the digital front end).
We are planning a move, and probably a basement renovation, so I will either run a single 20A for both speakers, or 2 x 20A lines, although I wonder if this might be overkill. I don't usually listen at high volumes, and the 100As have great dynamics even now, with the stock cables.
I was hoping to hear from some folks who actually are running ATC active speakers, as their real-world experience would be an asset. That said, my limited experience so far has been that 'everything makes a difference' -- sometimes, even if it's just peace of mind that each link in the system chain is strong.
Best, JAMES.
