Well, I have Amazon HD and I'm able to stream 24bit/192kHz through Fire Cube to NAD M17V2. I can also stream Amazon HD through the BluOS, but I prefer the Fire Cube / Amazon Platform using the FireTv remote instead of an app, using the phone or computer. Also Amazon Music include lyrics on most songs. Both streamers will do 24bit/192kHz. Bluesound has a little more laid back sound, maybe a little bit
cleaner, less noise, but not a big difference. I had Tidal Music service along with Amazon Music and I still preferred Amazon. I'm very happy with Amazon Ultra HD.
