Another new DAC: Audio Mirror

@gryphongryph 

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."

@gryphongryph I also use mine as part of the television/ps4 system. Fortunately, the replacement tubes are cheap and plentiful. I wouldn't (and don't) stress about it.

Also, if you are feeling stressed about tube life, you could consider the ifi idsd pro. I preferred the audio mirror to it, but did enjoy the ifi as well. It has the option to run either tube-based or solid state output stages, so you could go to SS when not doing critical listening.

Interesting about the ifi 
Is it easy to replace the tubes in the mirror dac ?
