As it turns out the Denafrips Venus 2 can play MQA files with a very simple solution.
The SMSL DP5 or SD9 streamer will directly interface with Venus 2 over I2S using a regular HDMI cable (no pin configuration required!) You can then stream Tidal Masters using mconnect software over DLNA and output the fully unfolded file over I2S. A 48kb 24bit MQA file will display 4 x 48kb on the Venus 2 indicating that the full unfold has been received.
And it's that Simple!
MQA + R2R = Audio Bliss 👍 Enjoy!
