Anyone been tube rolling this DAC? I'm open to Ideas for tubes and upgrades. Thanks.

tubes1988, does your Amber II play Tidal MQA content? I know it doesn't process/unfold MQA content but curious to hear if it even plays that content. 
I have the Amber DAC II, the Amero USB driver I downloaded for it to work with the USB port, has a switch to "pass though MQA" to disable software decoding of MQA.  I dont really understand what it does, I'm happy with with as is. Cheers.
Well it seems like Lampzator does not approve of tube rolling with this model, that's why the tube are inside. Oh well it still sounds great. Cheers.
