My goal here is to understand. I want to understand how my electronics work.

So, onwards.

Is there anyway to figure out an amp's max delivery (to speakers) and max draw (from the wall) knowing a few basic factors, like watts RMS per channel and speaker impedance?

Carrying on from that, I'm trying to assess PS Audio's P20, since it's built like an amplifier for AC. The specs say 3600 watts and 35 amps peak current. What does this mean? Does these number describe accurately the peak power delivery/draw? If a component needs to draw 70 amps of instantaneous power from the P20 over the course of a few milliseconds, is the 35 amp spec a hard cap or not? How can the deliverable peak
current
be 35 amps when the P20 can only connect to a 20 amp receptacle? What is the relationship between peak delivery and draw?

Where did I get the 70 amp figure from? Garth Powell's presentation on Audioquest's

Niagara 7000 (listen at 31min:33sec). It was part of his reasoning for why he developed a peak transient reservoir within the Niagara 7000.

Shunyata's

Hydra v3 can supposedly deliver over 100 amps peak instantaneous current, while the figure for the

Typhon QR is over 1000 amps. And all of this is supposed to come from the wall, i.e., 15 amps or 20 amps.

Neither Shunyata
nor Audioquest
power distributors regulate voltage output.

For reference, I have: two active monitors (Adam S2Vs) rated as consuming 230 watts max each (internal amps are PWM Class AB), a PS Audio Stellar Gain Cell DAC at 20 watts and a PC with 650 watt EVGA power supply running on the same circuit, currently plugged into a Brick Wall PW8R15AUD. I can't install dedicated lines where I currently live, unfortunately. That gives a total of 1130 watts (but let's say 1200 watts for ease of calculation) or 10 amps (1200w/120v). I don't understand how to apply power factors within the calculation, although I know that they will greatly affect the final numbers. I would guess actual consumption to be around half that, around 5 amps.

I don't know how my components draw power instantaneously rather than over time. Frankly, I don't even understand how my components draw power over time in terms of the electrical mechanics. Powell drives a hard line between amplifiers and other components, for example, and I wish I knew why.

I'd be very grateful to anyone who would take the time to help me with these questions. I can easily summarize the answers as we go, as well.
