Amazon Launches Lossless "Hi-rez" HD Music Service

Simao...I dont do Tidal.   

Your ears will often times tell you you are hearing what you anticipate hearing.  But the fact is that fidelity ends with the recording session...typically analog.  You cannot take an analog recording converted to 16bit digital and make it "better" by reprocessing it into a 24bit container.  How could anybody believe that?

Unless a recording was originated in a 24bkt digital studio, it can never be a "real" 24bit recording.  An original 16bit (CD) recording can never sound better than the original 16bit recording no matter what you do.

People hearing a difference between two or more services are most likely hearing a Difference in the delivery of the music from the service rather than any increases in actual fidelity of the source file. Same as when people hear differences between FLAC, ALAC, WAV etc. As has been mentioned earlier, increasing bit rates into a larger package does not and will not ad extra fidelity, air, soundstage etc if not on the original master! If you exchange four quarters for 100 pennies do you have more money? 😂

OK...I bit the bullet and started my 90 day trial. I've tried to listen to "Ultra HD" selections on multiple versions of the Amazon Music app. First of all...when you start the trial/subscribe...the welcome screen adds an "HD" to the "Amazon Music" logo. 
So right now I'm listening to "Ultra HD Fleetwood Mac" on my FireTV. I finally figured out that to see the resolution info I need to click on the more(...) selection...a screen comes up and tells me that to see resolution info I need to click on the bar on the screen and then "got it". It shows that the maximum resolution is 24/192, the device I'm using max is 16/48 and so I'm listening to it in 16/48 (Probably really 16/44.1 or CD quality).
Other devices do something similar, although it isn't consistent.
So it seems odd that my FireTV (I didn't yet mention that it is 4K...it is) only has 16/48 capability. Can someone tell me WHAT DEVICE has 24/192 capability?
I was on chat and the phone with Amazon before I decided to just try it...they couldn't tell me how to see what the resolution of a particular selection is without actually playing it. The person on the phone tried to tell me there are 60 million Ultra HD selections....no not really true. The person I was chatting with went around and around before I figured out that HD means 16/44.1 and Ultra HD means something greater than 16/44.1 but not necessarily 24/192.
So far I have only found a few Ultra HD selections.
Don't get me wrong....this is a GIANT step in the right direction. Neil Young is actually telling people on Neil Young Archives "Sing Up!!!". Let's see where this goes.....

By the way it's more like changing 4 quarters for a mint silver dollar.

I just found a lot of the Sheffield lab collection on Amazon HD. Fantastic stuff. Very well done and high dynamic range. (even if it's 16/44)

Just type in Sheffield labs in the search section. Have fun!
