Well Amazon might not have "Killed Tidal" but I am suitably impressed after actually getting it to play on the " big rig".
Streaming to my two vintage rigs was easy as the android app saw the 2 Chromecast units instantly and played to them perfectly and it sounded good.
But my Ayre EX8 did not show up as a source and mconnect does not support Amazon yet.
On the iPad it was at first considered even worse as NOTHING showed up as a source.
However with perseverance and the help of 2 members ( thx Rick and Robert) I got it to work on the big rig.
Out of the iPad, Lightning to female USB adapter, USB audio cable to a powered reclocker, USB audio cable into the EX8.
The EX8 does not have a powered USB audio input so the reclocker is essential to the party to supply good clean 5v USB power.
Ok so with this setup I was able to play same album on Amazon and Qobuz switching between USB audio and Ethernet inputs to compare the SQ.
I have to say I might just give the nod to Amazon atm.
Although a lot of variables, maybe the reclocker is really helping out?
Maybe my Ethernet is hampered by being 75 ft from the router and running through a switch?
Tough call but I now have options.
