For 15 Euro per month (family membership 20 Euro) the entire repertoire of 50 million songs can be accessed in lossless CD resolution (16 Bit/44.1 kHz), and several million songs are even available in HiRes with up to 24 Bit and 192 kHz clock. Amazon calls it "Ultra HD". Amazon Prime members pay only 13 euros a month. New customers can test Amazon Music HD for 90 days free of charge. Membership can be cancelled at any time. For a limited time, Amazon Music Unlimited members in the USA, UK, Germany, Austria and Japan can upgrade to Amazon Music HD for 90 days at no additional cost. The service can be used in a web browser or on a Windows or Mac computer in an Amazon Music desktop player, as well as on newer iOS and Android handhelds and on all Alexa-capable Echo devices (2nd generation and higher), Fire TVs and Fire Tablets in HD quality. To use the full sound quality - especially the HiRes resolution - a HiFi device is of course recommended. Numerous manufacturers have integrated access to Amazon Music (also in HD) into their devices, including Denon, Marantz, Onkyo, Pioneer, Sony, Sonos (only up to 48 kHz), Klipsch, McIntosh, Arcam, Bluesound, Rotel and many others. Amazon Music HD can also be streamed via Chromecast and Airplay.
