Amazon Launches Lossless "Hi-rez" HD Music Service

I am on vacation now and so I will have to wait until I return to try it on my Bluesound gear.  I currently stream Qobuz through Bluesound and it’s a very good quality but I find subtle differences between that and both CD replay or ripped CDs played back via Bluesound, so there is some room for improvement.
i currently use the limited Amazon streaming that my Prime Membership buys but it doesn’t do well with hapless playback.
  I do wonder at the economics.  Amazon has the cash reserves to take a loss on this but once they have driven the the high Rez streaming competition out of business can raise the price through the roof

Sadly, due to the Google vs Amazon war the neat and effective Chromecast Audio is not, nor ever will be I doubt, compatible with Amazon Music.   This means it is a no-go for many users, a shame as it is £10 a month cheaper than Qobuz.

Awesome overview of streaming services available. Should be very helpful to members new to streaming.

Note: not all services are covered. For example, Qobuz.
