Amazon launched a high quality streaming service today, Amazon Music HD.https://www.amazon.com/b?node=14063680011
It has what they are calling HD (16-bit/44.1 kHz) and Ultra HD (up to 24-bit/192 kHz) tracks. They are offering a 90 days free trial then it is $14.99 / month ($12.99 / month for Prime members).
Considering the number of us who have Prime memberships, it would be amazing to see an Amazon Music HD client added to the BDP-1/2/3/Pi like with Tidal and Qobuz. I know there are a lot of other enhancements in the queue, but one can always ask.
Here is info about the trial and pricing from their site:
This 90-day free trial offer is a limited time offer. This offer applies only to the Amazon Music HD Individual Plan and the Amazon Music HD Family Plan and is available only to new subscribers to Amazon Music Unlimited. After the 90-day trial, your subscription to the Amazon Music HD Individual Plan or the Amazon Music HD Family Plan, as applicable, will automatically continue at the monthly price of $14.99 ($12.99 for Prime members) plus applicable tax (if you selected the Amazon Music HD Individual Plan) or $19.99 plus applicable tax (if you selected the Amazon Music HD Family Plan) until you cancel.
