Amazon Launches Lossless "Hi-rez" HD Music Service

Only if Amazon have off-line ultra HD. LTE is not reliable at some location and insider building. I would do hard wired streaming at home or off-line on the road. Doing away from MQA is good if Amazon can do 192/24 or at least 96/24. My Oppo HA-1 and 105D can't take MQA.

I have the student discount Tidal subscription. Also I have the Oppo105 which has Tidal streamer build in (no need of USB). And I am lucky to have the last batch of Oppo205 (MQA decoder). As an audiophile and Tidal customer, I would stay with Tidal for a while until Amazon lower their UltraHD to $9.99 and with more 192/24 library.

44.1K/16bit is not a HD format. I don't know why Amazon call it HiRes. for most people an MP3 320kps is more than enough and compact on mobile device. For audiophile folks on this forum, 96K/24bit is barely minimum. I would say 192k/24bit or DSD64 get you into real HiFi. And only Qobuz have the most HiRe. Tidal's MQA is 2nd next to Qubuz.
