Hi there 
I am on the fence about buying a Sonos Arc. The Arc supports both Dolby Digital Plus, TrueHD and Atmos, but no DTS formats.
My questions is this: If i have a movie with DTS HD-Master, i know Plex can transcode it, but what is the best possible result format? Can it transcode to TrueHD (aka keeping it lossless) or what is the best case format i can receive on the Arc in such a scenario?
Thanks in advance
