Music streaming – MQA
MQA är en högupplöst streamingteknik som ger dig original masterinspelningskvalitet från en musikstreamingtjänst. Det är kärnan i TIDALs stora TIDAL Masters-katalog. Och även om den är långt ifrån uttömmande, innehåller den några ganska otroliga konstverk.
Det här är album som du kan streama i upplösningar på upp till 24-bitars, 192 kHz, vilket ger dig en häpnadsväckande upplösning som hjälper till att skapa en djupare, mer uppslukande lyssningsupplevelse.
Inget av detta är dock utan vissa förbehåll. Även om TIDAL Masters kommer att erbjuda 24-bitars, 192 kHz, betyder det inte att det kommer att nå dessa otroliga höjder bara för att det är en Masters-bana. Faktum är att de flesta inte gör det. Majoriteten av mästartitlarna kommer att sitta någonstans mellan 48 och 96kHz, vilket visserligen är långt ifrån den glänsande 24/192 som ständigt annonseras.
Även om, ja, inte alla Masters-spår är rejäla 24-bitar/192kHz i upplösning, är det du får långt bortom CD-kvalitet.

Musik streaming – Roon ready
Roon ready innebär att tillverkaren har implementerat roon labs RAAT-nätverksgränssnittsprotokoll direkt i enheten (nätverksförstärkare eller streamingspelare) och blivit en certifierad partner för roon. Därmed fungerar strömmande spelare / förstärkare med den högsta strömningskvaliteten från roon via RAAT, som var tillgänglig vid tidpunkten för utvecklingen, och möjligen. senare via uppdateringar.
Roon-testad innebär att enheter har en inbyggd USB-DAC, ChromeCast eller Apple Airplay, som alla är kompatibla streamingalternativ och därmed "slutpunkter" för roon-universum. För att få "roon testad" kräver det också att enheten har granskats av roon labs QA-team och därmed registrerats korrekt i roon-programvaran för optimalt strömningsutnyttjande.
Enheter som bara är "roon-testade" kan inte dra nytta av den fullständiga Roon-funktionaliteten och ljudkvaliteten som uppnås med roons RAAT-protokoll. För att strömma med RAAT krävs att enheten är "roon ready" -certifierad. Strömningskvaliteten för ljudet för "roon-testade" enheter beror därför helt på vilken typ av streaming som används och dess begränsningar.
