Hey Y'all,
I'm trying to refine the AC power my stereo system sees at the source. I am wondering if anyone makes high end USB-A wall charger of really high quality. I am finding that these wall outlets that come with the likes of most streamers or phones, or even aftermarket ones by Belkin and Phillips have really high levels of variation in both video and audio performance. My streamer an amazon fire tv 4k max, is using a WireWorld Starlight 8 usb-micro to USB-A cable; but must use a wall outlet for power. I haven't been able to thus far find anything that boasts copper materials or even gold- or silver-plated contacts and was wondering if anything out there like this exists. A premium build, maybe specifically designed for AV use like a premium usb cable is.
It's worth noting I've tried using the usb ports on my TV and AVR and the usb power sounds worse from that source, than from my Pangea SE wall outlet. This also applies to battery banks running the streamer, something in the dynamics and over sense of authority is missing. My Belkin ac charger does good audio but poor video, the Philips mediocre quality of both, this is somewhat typical of the others I have. The battery power does sensational video but mediocre to poor audio. The Belkin is a 12w charger, the others are 5 watts.
I use the streamer for hi res audio files from tidal and amazon music, and have done a lot of other upgrades, but find that the source gear power is especially important and surprisingly sensitive to overall system performance. Has anyone experienced this, and what were your solutions? Are there any high-end products out there for this application?
Thank you and happy listening!

Galium Nitrite based chargers are a big step up over switching power supplies (although still a small step down from linear power supplies):

A linear power supply would do a better job than whatever switch mode power supply you may be using now, but a linear power supply would cost a lot more than your Fire TV. So you are stuck with what you get now.

This gallium nitrate charger may just be the ticket. The microscopically thin metal used in the stock fire tv usb wall charger, causes a loss of body and bass in music, and a narrower color gamut. While I could probably find better results from alternate streaming devices and power options. I do like my fire tv 4k max and want to see about making my existing gear better.
My thinking was the most minimalistic design would be preferred, like as in not multiple charging ports and plugs in the charger, for less circuitry and material to pass through.
Are there any options in the gallium nitrate types that are single USB-A charger, and possibly gold plated, rather than the industry typical nickel.

Hey ya'll,
Trying to keep this alive, as I haven't decided on the proposed solutions for my source gear usb charger. The gallium nitrite chargers by slim-Q have collapsible wall outlet plugs, I have to think that by design is going to use some kind of less significant wiring design and electrical contact. Are there any other gallium nitrate chargers that are compact, that plug into the wall and have fixed electrical prongs? Thanks, I'm open to any solutions for high end USB-A wall chargers.

Try a ifi iPower2, and maybe add a DC iPurifier2.
I have never used an amazon fire tv stick of any kind. I have a Ruko device which maybe is similar, I don't know. But I don't use it for music listening. Check out the ifi mentioned above.

I use a Teradak U9 (X1/X2 now I think) for its USB port to power my network switch.

Agreed, a linear power supply is the best option if quality is the most important parameter.
