Amazon Music Ultra HD

Okay,  Just an FYI for everyone.  I spent an hour with an Amazon Music tech and it can't be done...yet?

The titles are tagged as ULTRA HD, but apparently there is no way to actually search for just that parameter.

He said they will try to incorporate this into the next update or two.

I hope you try the 3 months free first. The only OS I see that works with it is BluOS.
If you are streaming thru yer phone or computer you will most likely not hear any difference.

I do use a Node2, so it works great.  I've spent the last 4-5 weeks going between Tidal (MQA), Qobuz (Hi-Res) and Amazon Music (Ultra HD).

I started with (6) songs that I knew well and that were all available in each services highest quality.  After the first week, I had pretty much convinced myself that Qobuz was just a smidgen better than the other two.  However, after a few more weeks and about (50) different tracks, I now really can't tell a difference?

I have since cancelled my Tidal and Qobuz accounts.  The kicker was the $7.99 a month for Amazon versus the other two.  I can always go back, but so far, I'm pretty happy with the sound quality, amount of material and of course the price.  YMMV and this is just my opinion, so take it for what's it's worth...

As long as you are happy with BluOS, great.
I thought Amazon was supposed to have such a grand library.
Jeffery Foskett one album on Amazon 
12 albums on Qobuz.
Enjoy.
