Improving streaming SQ


I have an Aurender A10 and stream Tidal and Qobuz.  I'm looking for an easy and cost effective way to to improve streaming sound quality as it seems to fall a little short of my ripped CD's.  Artistic Fidelity makes an ethernet galvanic isolator (GISO GB) that plugs in between the CAT 6 cable and the Aurender.  I'm wondering if any one has tried this or a similar product and what your experience was.  I don't think this product is available in the USA, but I can get one shipped from Germany for 299 euros.  As always, any and all comments are appreciated!

Press the gear wheel icon on the upper right corner.  This will open the page.
It sounds like there IS a setting for masters but in a desktop app, might have to load it onto my pc to check as under the android app max setting is hifi.

OP, as said top right corner there is a little gear wheel, this will open a few more settings like normalization and streaming quality etc.
So just downloaded the desktop app and there is indeed a selection for masters available under streaming that is not shown using the tidal android app.
Very interesting.
You keep on learning!
On the desktop app on my pc is where I found all the info about the Masters setting.
Thx Mr_m.

As you can see from my previous posts it is ONLY to be found on desktop app, it is NOT shown on android app, only 3 choices there, 4 choices on desktop app.
