We have very different points of reference. And childish comments like:
"Did they say what colour power cord we need to be using for the best bass and brightest high end???"
don't earn you points with anyone.
Wall wart (12v power supply) DAC noise?

This recent experience of mine that`s related to power supply noise in this thread, in my case my a WAV. ripped music laptop`s external USB 2 Hub, and the unexpected SQ improvement results for what I did..
This laptop has been in use for close to ten yrs. 24/7/365, and for the physical placement of it on a shelf mounted on the back of my main A/V rack, I have been needing to use a USB Hub for cable management for 5 various attached devices( Track ball, a USB 20MhZ `O-Scope for displaying Lissajous pattern on the laptop, a USB to S/PDIF converter for the laptop`s music into my DAC, with (2) Ifi brand filter/re-clocker dongles in the USB feed to the converter)..
All USB devices seemingly powered by the laptop`s USB port, even though the multiport USB Hub came with a 3 amp rated non switching wall wart that is plugged in,.
After I added the 2 iFI filter/re-clockers USB dongles almost 3 months ago, I noticed that the laptop`s cooling exhaust port temperature was much warmer than before..
Stay with me here..
I had run across a thread here on A/K some months back, where I gentlemen was creating a USB split power isolation cable hack.
So I started thinking about hacking my multiport USB hub to break the laptop`s power feed inside to take off the handful of connected USB devices for nothing more than giving my poor laptop`s internal power supply a rest, not including it`s wattage upgraded SMPS brick.
I sincerely believe that the laptop`s ripped music`s SQ is better !
I went into this with nothing more than to relieve my laptop`s USB power supply loading thermal considerations of a burden with no expectations of any SQ changes, so no expectation bias was involved, and I hear this machines music all day long through various audio systems in my house, so I`m sensitive to changes to it, whether expected, or not...
Just thought to pass this little unexpected experience to this PS noise thread,
Carry on, folks.
