That an interesting thought, I tried the Onkyo music app because of good revues. I’m not sure if UAPP works the same way but the Onkyo player requires me to import my music. The issue seems to be that Amazon has a proprietary encoding (for DRM reasons) that Onkyo player can’t decode so I ended up importing a bunch of gibberish.
What I hope is someone will read this who has encountered the same issues and provides a forehead
slapping 'Why didn’t I think of that" solution.

UAPP replaces part of the Android OS that F&%$ up the music output, which causes resampling and some other definition limitations. My brain is not far behind yours in age-related decrepitness, and also got bumped in a car accident 
, so my ability fake theoretical theories and explanatory explanations is hampered, except at work when I’m being paid to appear coherent.
It wasn’t an “accident” the 17 year old girl was leapfrogging others on the road when she lost control.
So I think I’ve found my answer and it’s not what I wanted to hear.
So I went to the UAPP website and read through their info. Then went to their forum
and that is where I saw an administrator’s answer to a question like mine.
His statement is “Amazon does not have a public API and cannot be supported”
Later in the thread, after multiple questions of when and why, his only comment was
that he could not comment.
I guess I cant be too bummed out. The phone cost me less than $140 and I can load it
up with CD quality music to my hearts content since it has an SD card slot. It also Support AptX to my Sennheiser Momentum 2 phones.
OTOH, For Hi-Rez I ca fire up one of my computers and plug in my phones and listen there.
I guess my next quest is to find a cheap way to feed Hi-Rez to my Yamaha R-N500 stereo receiver and see how it sounds on speakers.
Thanks for your comments.

I wonder if someone could shed some light on why I get white noise or fizzy sound out of my amp. For example, I would be listening to music then suddenly amp would just go into this white noise or fizzy noise, I have to switch it off then back on to use it again.
Thanks
When the noise happens, does it go from not occurring at all to all of the sudden occurring? And is it something that’s a low level but you can still hear the music playing, or does the listening experience go from hearing music to only hearing white noise?
I think I’m having a noticeable DC offset problem. I’ve heard my DAC buzzing a few times (heard it happen 3 times) which I assume is the transformer vibrating due to some DC leak. The buzzing doesn’t happen often so should I still be concerned? I’ve read it can damage your equipment. It will be difficult narrowing down what device is causing this since the buzzing noise doesn’t happen often, so doing this is out of the question.
I’m aware there are devices like the iFi DC blocker and the Emotiva CMX-2 that were mentioned around here which should do the trick. Are there any other products that do this (preferably with more outlets)? Will they affect sound? Can power generators help with this? Are there any other solutions?
Thanks for any advice/input.
You have pretty much nailed it.
does it go from not occurring at all to all of the sudden occurring? Yes and sometimes it will happen when I just turn it on however majority of the time is when I am listening music
And is it something that’s a low level but you can still hear the music playing? No it literally all I hear is the noise, till I don’t switch it off then back on.
or does the listening experience go from hearing music to only hearing white noise? Only hearing white noise.
Anyone any suggestions
How are you connecting the amp? Is it paired with a DAC? I’d first swap the interconnect cables between the amp and DAC, or whatever the connection cable is that you’re using between the amp and your computer; swap the power cable and maybe the power strip or outlet it’s plugged into. If that doesn’t change anything, try using a different source (computer or DAP) with the amp to see if the issue follows.
I was having fun reading at a ASR thread and then I remembered your issue.
Hope this helps. Cheers. 
Unfortunately, I don’t think it’s an issue with the GPU on my macbook. It happened at random times whether I’m actively using the DAC or not. I try to observe what devices are running when the buzzing happens but still no luck with finding the source.
Appreciate you looking out though, thanks!
Did you every try any external device? It could be a power issue, I believe they can come and go depending upon what other devices/appliances are drawing off the circuit and when.
What do you mean by external device? Like just a different device entirely?
In that case, I haven’t because the buzzing still happened even when the DAC or macbook are not being used (if that’s what you meant).
At this point, the only other option I can think of is to try plugging in the DAC at someone else’s place that’s in a different grid, to see if it is really a DC offset trigger. But with the buzzing being so inconsistent, I’m just not sure how to go about this issue.
I also asked Tim from Holo what he thought and he assured me the DAC is working perfectly.
I meant like the IFI thing.
Ah, no I have not tried any of those yet…
Trying to learn more about the problem first before jumping into anything (plus Amazon has it as out of stock atm).
It can be maddening. I’m sensitive to any kind of buzz so I understand the frustration.
I’ve tried the Emotiva and Ebtech Hum X. Neither worked for me, but I likely had a different issue. You’re welcome to borrow the Emotiva. It seems like it might be your electrical feed. It’s possible that a regenerator can address, but I don’t have direct experience. Good luck.
Still trying to isolate the problem as it is happening a bit more frequently, albeit in shorter durations. But I will let you know, thanks!
I’ve read that regenerators don’t filter offset (at least the ones available on the market), unfortunately.
Darn. I haven’t experienced this with my same DAC, but I’ll monitor. Perhaps try plugging it into an outlet in a different room. I’ve had to deal fairly extensively with buzz/hum, and part of the exercise (as you know) is isolating the device vs environmental factor(s).
Do you still experience it? Or were you successful in isolating the appliance?
If you still are and are hearing it through your transducer then it wouldn’t be DC offset (from what I’ve gathered).
