I've forgotten Roon for multichannel. I think it is very hard (or expensive) to get it working. UHD3000 is not streaming native DSD 2ch nor 6ch. The internal DAC doesnt Chinoppo can do both type of streaming via HDMI from SACD isos although should be open as a video ISO after setting the NativeDSD option on setting. At this point, the raw stream is sent to the AVR where it is converted to analog. I prefer the conversion on AVR because the DAC will be better than Chinoppo's Hi. Chinoppo is a clone of the original Oppo 205. The firmware is exactly the same, although the hardware is not exact, but very similar. It supports SACD (sterero and multichannel) and DVD-Audio. Both of them can be stream via HDMI. I've ordered M9203 and the total cost delivered to Spain si 520 euros. I don't know if I will pay duties, although the seller assures me that it won't pay. As a controller app there is an old Oppo Controller app compatible, but it is not update in years. My intention is to keep Zidoo for video and use the Chinoppo only for hi-res audio.
