What type of wire for dedicated 20A AC lines?

@kingrex

I’ve read different opinions on running all gear in system through single 20A line versus multiple. I don’t know enough to have an opinion myself yet on this.

If someone were to install three 20A lines for a single 2ch system, let’s say, how should they determine the components to be driven by each line? Let’s say system has 2 monoblock amps, a preamp, a digital system (e.g., dac, streamer/server, sacd player, maybe external clock), an analog system (TT, phono pre). What goes to each of the three lines? or two lines?

FWIW, if your going through the trouble of adding a line, add 2 to 4. Its not much more money and you will hear the difference.

I agree! I installed four dedicated lines one for each mono block amp, one for digital and one for analog.

So here's a beginner's question.

If you're putting in a dedicated 20amp line, or even 2 or 4 of them, and if there are no free spaces on the main breaker box panel that you currently have, do you also end up putting in a new larger panel?  Does a sub-panel solve that?  And what are the other upsides/downsides of a sub-panel?

@ditusa , yes I was planning on installing two lines, and then playing around with what configuration sounds the best.

For others to reference, I’ve read it’s important to have all of your lines on the same electrical phase.  The electrician will know how to do this with your breaker panel, but probably won’t know to do it without being directed.
