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!

It is not accessible through the BluOS app.  You need to go to the actual Tidal app.  
Yes it does carry over.  The Tidal app is your subscription to their service.  Whether you access that subscription through BluOS or another app from a different manufacturer, you are listening to music from Tidal via the settings in your subscription from Tidal.  So, no matter the streamer in use, the most accurate sound will be with normalization in the off position.
Then I should be good as it is switched off via the Tidal app itself.
All good to know as I did not know if it carried over.
Again thank you
Good thing to know about Tidal. I have been paying the premium price for Tidal for quite awhile. I shut this switch off too, but also noticed I had my streaming set for the "HI-Fi" mode and not the "Masters" selection. I hadn't realized it till I looked in the settings. This is my fault and should have checked it sooner. The sound with these two simple changes improved the sound quality pretty dramatically. Lesson learned.....
Mr-m.
I am on Tidal premium too but do not have a "masters" streaming option showing?
Just normal, high and hifi.
@uberwaltz,
I don't think there is a 'Masters' streaming option from the list.
If I do play a Masters album, my DAC shows that the file is in high resolution.
