Well i can equip M2 with the same Broadcom opto receivers as i did my Dave. Feed them from M2's internal battery to stay totally noise freeYou missed the key part.
Mojo2 has to be paired with the MS to bypass its internal upsampling.
And the only way to connect them optically that I am aware of is to use OPTO-DX from Audiowise.
