I bought the A6 because with HDMI I can stream multichannel on my Meridian system. But then I found out only USING Roon. No one can answer why I can't stream multichannel directly from the apps in the eversolo, like Apple, Qobuz and others that offer Dolby encoded stuff. The Facebook group is for newbs. But I do appreciate it's multiple output features so I I can have it connected to various systems when needed.
