Unless you suffer from ground loop hum or other types of power interference, then no.

There are no harmonics in mains power?

I bought a (fairly) high end audio USB power supply and it improved the SQ of my DAC noticably.

I just scored a pair of Polk audio rti8's in fair trade of 4 Polk r150. I'm feeling stoked!

Just ordered my first "real" audio setup, its a 2.1 System, here is what I've ordered (should be here Wednesday, excited!!)

Speakers:

(2X) Infinity Primus P163BK

Sub:

Dayton Audio SUB-800 8" 80 Watt Powered Subwoofer

USB DAC:

Schiit Modi

Amp:

Dayton DTA-100a

Of course all the wiring to go with it, should be a pretty nice sounding setup!

I haven't taken an oscilloscope or spectral analyzer to a mains socket ever, I can always ask my professor about that.

Regardless, it shouldn't improve anything if the filtering and power supply rejection ratio is good enough in the DAC/amplifier/whatever itself. If it isn't, the design of the device is bad and broken. In all likelihood you shouldn't be trying to crutch it's flaws with add-on improvements like extra power filtering. There are nearly flawless products like the ODAC and Benchmark DAC1 in the market that handle that internally, settling for an inferior product and paying more for extra power filtering and other absurdities is simply cost-inefficient and most likely lands you with less performance. That is, if one is in for it for measurably/ABX-proof best performance. And if you aren't, you most likely shouldn't even try to bother with things like power filtering, the science and electronics behind sound or for that matter, basic logic.

If only everyone thought this way, we would have people with half decent systems. I keep seeing people with sub-£1,000 systems with mains filters, "upgraded cables", expensive "isolation feet" and such. If people just concentrated that money on better main components, they'd be much happier.

Uh, the power source doesn't matter.

It still has components that manage the power. If those components are bad, the power supply interference rejection is bad, and you'll hear all sorts of whirring and chirping according to your CPU/GPU/etc. utilization (because he computer PSU is a switched-mode power supply that has a lot of electromagnetic interference, ripple and whatnot, and this directly affects the quality of the current you get from any system). That means it's a bad design from that part, and fixing those design flaws afterwards means added price (at which point you could've gone with a more expensive product that was better in the first place)

Thank you a huge lot, I very much agree with your opinion. If a person doesn't know how to measure and test proper performance, then they should go with surefire products measured and proven to be nearly flawless instead of making audio seem like voodoo and going with these boutique brands. It's like going with Razer headphones because they "look cool" instead of a proven and decent brand, somehow that analogy most audiophiles seem to understand, but if you try to apply it to DACs and amplifiers people fail to see the point. It's relatively frustrating.
