It’s still a little confusing to me. What are we actually hearing? I have a Dragonfly rated MQA 24/96 and a Meridian Prime rated MQA 24/192. I have Tidal that has 24/44.1, 24/48, 24/88.2, 24/96, 24/192 and even 24/384.
You cannot equate PCM rates to MQA master sample rates.
Even if the USB interface of DragonFly is limited to 96kHz, it is sufficient for playback of MQA 192kHz tracks and MQA 384kHz tracks, because those MQA rates refer to the masters used for production, not necessarily the DAC playback rate, and definitely not the interface requirement.
I’m about to ask the same. But after reading all the comments. This is what I understand. Correct me if I’m wrong. (Edit: I’m really wrong, read more below)
(1)Tidal source 44.1/48 khz (MQA - available) or whatever MQA capable
(2)Tidal decoding (First unfold from 44.1k/48k > 88.2k/96 )
(3)Tidal send (2) to Roon
(4)Roon send to DAC and tell DAC “ORFS(original frequency sampling rate)” so that DAC know what’s coming.
(5)After this is all DAC job is to do the ‘Renderer’ thing(2nd or 3rd unfold if capable 88.2/96++). Roon most likely cannot track what DAC is doing anymore since most DAC likely not report back to Roon.
