Lamzator Amber 2 DAC

"Which Amber do you have?"

I have the original version, circa 2014.

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.

If you notice, there are production date labels affixed along the cover and the chassis which will break if you remove the cover. If you bought the unit new, you might compromise your warranty if the labels are not intact. I personally would only consider changing the tubes if one fails or they are old beyond the warranty period.
