Amplifier and Digital Streamer on Single 15A 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.

OP,

I recommend a high quality power distribution block for your gear. I have all of my digital gear and amps plugged into Nordost QB8. I found QB8 to be very effective in isolating and lowering noise. One thing I appreciate about Nordost is their modular approach...once you settle with QB8, you can add Qv2 and Qk1 plugin modules to further enhance the sound of your system. Each component in Nordost power conditioning is complementary, the more you add the better it gets.

You may wanna read up on Nordost QRT system before you buy a brand X power strip. 

I started last year with QB8 and now have full QRT system.

I would start out in the garage or wherever that 15 A circuit starts..start there..make sure panel connections are TIGHT..have an electrician do this, IF you are not qualified and competent and MOST importantly SAFE.
Check to see IF your dedicated circuit is on same leg as bigger motors in house, furnace, freezer, AC, heatpump, refrigerator, etc.. IF possible move to opposite leg of panel.
I always replace the breaker in lanel unless I know it if freshy fresh ! they corrode, etc..

Next ditch the el cheapo outlet on wall for at least a Hubbel Hospital grade.

Next I would get a Furman 15i or better to plug the streamer, network switch, wallwarts and other trash generating junk into...

The big dog I would run into wall direct, unless you hear no difference by running it thru conditioner...

even my lowly 1961 MC240 sounds better direct into wall over a bevy of $3 K conditioners...

IF you cant hear a difference, consider trading the Diabo...ya overspent ( this is 99.324% a joke )

also try running the server/streamer off another circuit with a hyper quality extension cord..make this up w 12 G and Hubbel Hospital grade components.. TO evaluate what happens...then you can judge IF hiring electricians to fish an outlet will benefit you.

FWIW, I try to actually follow my own advice....5 dedicated circuits in my reference room just for audio..

have fun

sounds like you have fantastic components !!!!!!
