WiiM has stated that airplay will never be coming to the current Ultra. Why all their other products have airplay except this one has never been clarified (Apple is to blame is a common unfounded rumour). All discussion on airplay have been closed or is closed on the Wiim forums which is mildly annoying.
Bringing up airplay also provokes responses as to why you would need it as there are alternatives A, B and C. And besides it is not (always) lossless. I get the impression these responses come from those that have never seen the extreme convenience of AirPlay. I use AirPlay plenty to cast audio that is not lossless in the first place (like internet radio). My family uses AirPlay for all kinds of stuff, they prefer convenience over sound quality any day (I know…). And it is very nice to be able to cast any audio you might have on your phone, regardless of the app it’s from.
I was extremely enthusiastic for the Ultra but cancelled my order because the lack of AirPlay is a downgrade and I’m not sure yet that using a different device as AirPlay receiver will not cause issues. Even if it has no further downsides I fell weird for buying a device that I know lacks something I would really like it to have.
Edit: I guess I’m just annoyed because I have and love the Wiim amp which is perfect for my situation besides the amplification part. The Ultra together with the Fosi V3 monos seem a perfect affordable upgrade.
