Amplifier and Digital Streamer on Single 15A Circuit?

I’ll shortly be setting up a new system, a Gryphon Diablo 300 Integrated (with DAC module) and an Innuos Zenith MK III digital music streamer/server.  

Unfortunately they will will be on the same 15A circuit in my house.  The circuit powers all wall outlets in my living room, but I can be sure nothing else is powered while I’m using my HiFi system.  

I know that many, Gryphon included, say to plug the amp direct into the wall and not use conditioners.   Also, I’ll be upgrading power cords to the Amp and Streamer, likely with AQ Hurricanes.

At first I was concerned it was only a 15A circuit, not 20A, but then I realized that even with the Diablo that has a max peak power consumption of 1900W, that during my use power consumption will never go high enough to trip the 15A breaker, unless I’m playing at insane volumes (I don’t).

I’m sure others must have run into this same issue. 

How detrimental will this configuration, having the amp and digital source on the same 15A circuit, be to sound quality?  And what remedies do I have - should I get a conditioner that will isolate the digital source at least and leave my amp plugged into the wall?

I hate the idea of plugging in an expensive piece of gear directly into the wall due to the possibility of a surge taking out the unit.


Use a shielded power cord on anything digital, and plug it into a unit like the Furman with SMP and LiFT. This is the cheapest I know of with those features:

Personally, I suggest you get it, and try your amp on it. If you like it, get a more advanced unit for your linear gaer, and use the strip for your digital and wall warty stuff.

Thanks for this.  Looks like this strip like this will help clean up some AC noise at a low cost.

One question is whether the strip would help isolate my amp from the digital streamer and noise it creates on the circuit?

I have my streamer-dac and integrated amp on a 15A non-isolated circuit. I am using power cords and plug it all into a PS Audio Dectet, plugged into the wall outlet. I like surge and spike protection for my rig. Like the sound I'm getting.

This Furman strip will not isolate digital. For isolation between receptacles you would have to move up the ladder in power conditioners. 
Erik suggested to split analogue and digital by using 2 different conditioner/strips.

Without dedicated AC lines you need to control the noise from the grid, your household appliances, and the contamination caused by digital devices.
PS Audio Dectet may be a possibility. It’s important to find a conditioner that is non-current limiting, meaning an amp can be plugged in without suffering a restriction in the power supplied.
