Class-A Amplification and 15 Amp Outlet

Pardon my electrical theory ignorance, but I have always been intrigued by the beauty of Class - A sound, as such, I am actively exploring a purchase. My question is based upon the power draw (even at idle) and the ability of a 15 Amp wall outlet to provide such without tripping. I have looked at the "big boys" from Pass XA160’s, Gryphons Essence Stereo & Antileon EVO to name a few. I do not have the option of installing a dedicated circuit in my unit. So, would I be ok if the electronics (including a DAC/preamp) were on the same circuit?

Thanks!!

Look at the idle and power rating for the amps. A 15A outlet is rated for about 1800 VA I believe, so long as the amp plus your accessories stay above this you stay well below that you’ll be fine.

You might want to swap to a better outlet though, especially if this is an old house. See more here:

 

You may also want to consider a conditioner with voltage regulation to ensure the voltage doesn't sag:

Of course, you can  also have a dedicated circuit with 12 gauge wiring and convert the line to 20 Amps. The beefier wiring, above all, will improve power delivery under stress.  If your circuit is going to be over 1,000 VA most of the time I'd suggest it.
