Another new DAC: Audio Mirror

Vlad has, builds sets of the 5977 tubes to just plug-in for replacement if needed. I actually asked him to send me a pair so I could experiment with other gear that uses 6922’s because of how terrific these mini tubes perform in the DAC.

Thanks teajay

Thank you teajay. I did buy a backup set of tubes that were already soldered to an adapter. 

I bought some 5977 tubes on Ebay even before I received my dac. I didn’t realizing what I was getting into with the bare tubes.

I was really interested in this Dac until I read somewhere that the tubes don’t last long, I planned to use the Dac with my tv as well as my Roon setup.
How many hours of tube life can one expect from this Dac? Even if I was not using it with my tv, I still listen for many hours at a time, often music is playing all weekend and week nights.

Don't know what you read or are expecting , but here's what they say on the Audio Mirror website

"Expected tube life for 5977 subminiature tubes is  >5000 hrs."
