Amazon HD Lower Price

Amazon ultra HD has a great interface. Using it with a Cambridge dac which accepts 24/192 and up converts  to 24/384!89. XLR to anthem p5

It's only a matter of time until Qobuz and Tidal become irrelevant. Amazon, and now Apple, and probably soon Google Play music, want this market. Last time I checked they had rather more money, customers, and additional products that they can tie into, compared to Qobuz and Tidal. They can keep the price low for years until they bleed out. Frankly they are not even on Amazon Apple and Google's radar. They are dead men walking. As consumers we will benefit from the lower prices from this competition. 

I’m not giving Amazon my money for something like this.  If I need a bag of organic sunflower seeds in 2 days, then Amazon is a necessary evil, but they’re not getting a slice of my music dollars and all that personal data too.  Even if they integrate with roon, which they won’t because they want all the data to themselves.

I didnot care for Amazon , it doesnot sound as good os tidal,or QObuz 
until it  sounds better then the above I wouldnot bother with them .

Go with Apple then, which also just announced hifi upgrade. They claim to protect your privacy and claim to collect less data. 

Google is going to have the best AI for recommending music. But they will collect everything about you. They still haven't stepped up on high bitrate yet either. I think they have to, I think they want this market and they'll just have to offer what Again and Apple offer.
