I can match the sample rate of the audio sent from Amazon Music HD, but the stream or the file is being altered somewhere before it hits my house. The quick and dirty truth is that I can't play bit perfect audio from Amazon Music HD on Windows 10, macOS Catalina (10.15.7), or a Sonos Port using coaxial S/PDIF digital output.

If a service or app can't output bit perfect audio, then I have big problems because I don't know where the losses are happening and how big the losses are. What is Amazon Music HD's highest quality? I started testing where I always start testing, with bit perfect playback. A USB cable between the computer and one's system is all that's required and Amazon Music HD will send along its highest quality. The limited number of options for playback isn't a showstopper in and of itself because many audiophiles use computers directly attached to their HiFi systems. One year on, the landscape is still Sonos, Bluesound, and Denon HEOS (I'm sure people will let me know if I missed any). Given that Amazon is notoriously difficult to work with, it's no surprise that we have so few options. There just aren't many options for listening in another way, such as integration with Lumin, Aurender, Auralic, JRiver, Roon, etc. Most of this use has been on my mobile phone or desktop. I've been an Amazon Music HD subscriber since day one and have used the service off and on since signing up. Let's take a look at Amazon Music HD, one year later. Not long after Amazon launched, Qobuz matched its pricing and now offers a $14.99 /month plan and $24.99 /month family plan. At the time Amazon's $14.99 per month plan was the lower than all the other lossless or above music services. Many people uninterested in the success of small businesses and good customer service cheered the new offering from the 1.7 Trillion dollar company. Just over one year ago Amazon launched its Amazon Music HD streaming service.
