Lumin M1 is now MQA certified, making it one of the rare MQA Roon Ready integrated amplifier that actually decodes MQA over Roon RAAT (*)
So the whole Lumin network player/transport product line S1 / A1 / T1 / D1 / D2 / U1 / M1 are now MQA certified.
Note * : There are other MQA Roon Ready products from other manufacturers that cannot decode MQA when playing from Roon. Another amplifier that is marketed as MQA Roon Ready does not appear in Roon partner device matrix:
