I’m using JPlay for iOs which is a DLNA control point running on iPhones, iPads and Macs. It works very well indeed with my Rose RS130, certainly better designed, more reliable and more consistent than anything other than, perhaps, Roon.
They run a certification programme, presumably similar to the “works with Audirvana” branding. I think it would be well worth Rose approaching them to get their streamers certified as it would provide useful marketing kudos and publicity.
