I started last year with Qobuz HiRez. Great quality but cost is not proportional to the gap with competition. Then I moved to Tidal HiFi as my Dac can manage MQA. Great quality and GREAT App: to me and my needs this is the best interface on the market. I recently moved to Amazon HD and... this will be my choice. Library is huge. Many HR albums and songs up to 24/192. No need to pass through MQA decoding. The QUALITY of what you listen is, to my years, slightly better than Tidal (More detailed) and on par with Qobuz. CHESKY RECORDS library at CD quality !!! This is something I was missing both on Tidal and Qobuz. The cost of 12.99 for all this makes it an interesting solution. And I’m sure Amazon wants to increase its market share and will continue to offer more at less with respect to the competition considering its financial strength as a company. Weak point? The interface! Very "basic" and far from the great functionalities found in the Tidal App. Example? I can’t save MY preferred Artists or Albums so that I have my selected list to choose from. In Amazon IOs App everything is melted together: your favorite Artist with tons of others just because for even a single song they are part of a Playlist. I really hope this will be fixed in future releases. In a summary: Amazon HD offers a huge library, even at HI Rez quality, with great sound quality, making available the Chesky Records library at 16/44, at a competitive price but... with an interface that needs improvements.
