Just a big i have discovered - if you play your tracks to the M-CR611 via connect (eg using an iphone as your playlist and connecting on MCR611 as an amplifier this is great as an amplifier via connectas an airplay receivernow only airplay receiver listable- then i discovered something - i tried comparing it to the spotify airplay by switching the deistination for the spotify to Airplay - (to be honest theres almost no discernible difference) but wanting the freedom of my phone back i discovered that the Marantz was no longer selectable as an amplifier.....

The only way i could get this to work again was to turn on spotify app on Amazon Firestick, start controlling this as a fresh amplifier which then allowed the Marantz amplifier to be selectable again - a strange bug indeed as leads to delays in connection
