Welcome to the dark side of UK audio enthusiasts ordering from US Amazon to get the Wiim Pro in our hands early! Bought mine in December cost about an extra £20 for shipping but worth the investment over the wait. I have not tried streaming Amazon HD because I have active Qobuz and Tidal subscriptions and having all 3 seems a bit of overkill.Received Pro, ordered from wiim US amazon store to UK as out of stock this side. Love it especially for Amazon music, on that front wiim app plays UHD content flawlessly but UI not as good as android app. Can use Amazon app but only goes to cd quality when selecting Pro as output device, searched online and this seems limit, does anyone know differently?
