Okay one question do you prefer the Asgard 2 power cable being plugged in from a power brick or from an outlet from the wall?
I have been plugging all of my audio equipment into UPS units that have "TRUE SINE WAVE" power signatures. Combo of Eaton and APC.
For my smaller power-draw devices: Eaton 5125 "1500" Technical Specifications here:

For my larger power-draw devices: APC SUA2200XL Technical Specifications here:
http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=SUA2200XL
My ASGARD 2, Home Theater PC (Foobar 2000 or JRiver 20 Media Center software), and DAC run off the Eaton
The HD Television (Major reason why you MUST use a true "SINE WAVE" UPS otherwise
you may get dangerous "power pulses"
when running off battery power!) and surround sound setup all run off of one of our APC SUA2200XL chassis behind the Entertainment wall.
To be clear, in both our old apartment, and now in our house, we have never experienced power issues or noise/interference from power contamination with this setup.
Before we had it, we lost a lot of equipment to a power surge from a lightning strike, so I will never allow our high-end gear to be plugged directly into a wall socket again. Its' a PAIN and large cost to replace all of it. Large enough that it justified putting commercial-grade UPSes in place. Expensive? Yes. But still cheaper to own than risking immediate or long-term intermittent damage troubleshooting headaches from a power spike. And after we lost lost power for 3 days after last year's hurricane, it was AWESOME being able to run our bare essentials for all three days and have small lamps powered at night! (Didn't have a generator when we were still in the apartment last year.)
Can you get away with a $1-200 UPS? Sure. But if you spend north of $500 on headphones, and north of 10 thousand dollars on your HiFi and Television setup, it seems as silly to me as cutting corners on the protector case for your new $300 + dollar smart phone to save $20-30 on a case that might not protect it from a fall from your coat pocket... Not to mention that it becomes less likely that will get CLEAN PURE SINE power with very low harmonic distortion, no static or humming noise in that price range. But more power to you if you find a deal!
