Amazon Music HD..... Not For Audiophiles

That is interesting.  I've been wondering when Roon would support it, mostly because of my Prime membership. 

For me a service has to be supported by Roon for me to really get into it.

Tidal 's marketing is pop, but it's catalog is far bigger than that.

Now that I know the catalog of music there isn't all that I can relax about it.

Tidal HiFi didn't cut the "audiophile" mustard for me but it was fun to explore other music for a year.

From what I've read elsewhere, for Roon to integrate with a streaming service, the streaming service must regularly (daily?) run a custom interface to dump the metadata for all the content in their library, so Roon can make the required updates on their end.  In mid-2019 I read that Roon had eclipsed the 100,000 subscriber threshold.  The question I'd have is whether a huge company like Amazon would develop and support a custom interface for such a small number of subscribers (as only a subset of that 100,000 would opt for the Amazon subscription)?

Amazon HD: I wasn’t too impressed with catalog and more importantly the availability of my favorite artist in high resolution. For my personal taste in music along with Aurender’s superb Conductor app, Qobuz offers the best streaming experience.

Amazon HD has 50 million songs and has Apple TV and Amazon cube apps.

It sounds great to me, even in CD quality.

I find High Rez "way over rated" in most cases. 

Good original recording mastering counts more than High Rez mastering as far a sound playback quality, IMO.

Lots of Amazon haters out there.
