Well, strange that the Marantz tech services explain that only Airplay is supported.
I am using a Marantz receiver (NR1504) and yes, I’m having the airplay limitation problem streaming only with 44.1/16 bit quality when using Roon software.
But I also have a Plex mediaserver running in the network (on the same physical device as the Roon core is running) and with Plex I am able to stream my high resolution files with 192/24 bit over the network and in this case the airplay protocol is not used.
So, how are the tech guys from Marantz or the guys from Roon going to explain this? I am able to stream my highres files with a free piece of media software and the well paid roon software is not capable of doing so? Why?
And while I’m sending this post and reading more about what is supported I read a roon post on thread Roon Initial Setup explaining the following:
What??? Not supporting DLNA/uPnP ?! Why !?
