Amazon Launches Lossless "Hi-rez" HD Music Service

I am a Prime member but this would be my first time with any service. I have a nice DAC but need the software/ hardware(??) between like Bluesound as I've read.....not sure how to link the service to my DAC. Don't want to use a computer or phone/ tablet. What are the units Amazon HD can work with?
Hope I explained that right.

Some [Some] current Amazon Products, Sonos, BluOS products, Marantz, Denon, etc. [Note: they may have restricted maximums for resolution / decoding]

I got this on another forum

"Those settings are for the "offline listening" downloads that are tied to your Amazon Music / Music HD player and streaming subscription. Cancel your streaming subscription and they're gone.

Purchased downloads that you can keep permanently come from the regular Amazon store, in MP3 only. From Amazon's perspective it's natural to cross-sell, but I think a lot of customers are going to be confused and unhappy

.

so even though in Amazon HD you have the option to select HD downloads after you purchase a song, you only get an MP3 file when you do it

So Bezos would do something like that.

I've been using my laptop pc via usb to my dac and compared with Qobuz, Amazon HD does not sound harsh but the sound lacks substance.  Seems too thin and polite.  No punch.  Voices and instruments do not have that palpable presence.  Qobuz is better in that regard but the sound is bit harsh and more digital like.  What do you guys hear?
