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

Uber...do you still have your Bluesound equipment?  I’m guessing not or you would have tried it by now.
  I upgraded to the Bryston BDA3 for my main system but there is no Amazon tab as of yet.  I still have my Bluesound equipment (mainly using the Node2 into two HT systems elsewhere in the home) but I am gun shy about doing a BluOS update, and have avoided doing them for months, because doing updates had led to problems in the past).  Maybe I will just wait for Bryston to add Amazon

most of my Bluesound issues related to not all 4 of my units in the house successfully updating in sync.  The Bluesound updates were frequent and occasionally one player would get hung up.  That somehow led to all of the players failing, and would require calls to Bluesound.  My main system is my 2 channel system and the Vault2 there has been superseded by a Bryston BDA-3, but I kept the Vault2 in.  My other systems have Node2 players.  Life has been quiet in my Bluesound Universe by refusing to do updates, and it isn’t worth disturbing the peace to add Amazon.  I’m pretty happy with Qobuz.

I first got an upsampling DAC about 10 years ago, PS Audio Digital Link III.  While I intellectually understand that upsampling shouldn’t sound better, about 90% of the time it did.  I listen primarily to Classical Music, and upsampling would increase the believability of the Sonic picture.  The soloist, percussion, strings , brass and winds seemed to occupy their own little zones, as they do in a real concert, .  My present DAC, the Bryston DAC3, has an upsampling feature and I don’t use it much, but the results are impressive when I do.  I have to say that the algorithms that determine what should be added to a 16 bit recording do a damn fine job.  Maybe it’s different
for other genres, but I don’t listen enough to comment.
  I will now sit back and watch as others tell me that I shouldn’t be enjoying what I enjoy, and that I have no street cred as an audiophile.

btw..was Amazon Music Server down today?  I don’t have the new service but I did buy many Amazon mp3 downloads years ago and usually stream them to the bt receiver in my car, and I kept getting a lack of service notice today
