Another new DAC: Audio Mirror

I ordered it after conversing with Vlad. I wanted something on par with my analog front-end? Hopefully it ships today or tomorrow. I did not go for the upgraded version, easy enough o accomplish at a later date. I use Audirvana and have limited experience with digital. Anyone recommend the Audirvana settings for this DAC?

Vlad has a pair of 5977 tubes soldered together, and attached to a 9-pin adapter, which inserts into a standard 9-pin socket.  So there are two pairs of these = four 5977 tubes.  What's nice is you can roll a pair of your favorite 6922 / 7308 etc. family of tubes into the T3 if you prefer a diff sound.

Hello Folks,
I think I need to clarify something I saw on this forum. It could be my mistake when I replied to one of my customers about tube life of 5977. It is 5000 hrs. not 3000 hrs. Please look at this link where it is  showing tube specs. The life is 5000hrs at 30 degrees Celsius ambient temperature. Here is the link:

Got m eyes and ear on a used or New PrimaLuna Stock Evo 100 Dac (I know its not a fair fight...the evo is twice the price...but one of our members got the MAXED out Version $2400)....so stay tuned for this update!!

I got my Holo Spring2 KTE version about a month ago and it is fully burned in. All I can say that this DAC is fantastic. I am using the I2s input with NOS.Tremendous trransparancy, globs of detail, glorious mids and great solid bass..Highly musical. I don't have a Audio Mirror to compare unfortunately but did so with my buddies PS Audio Direct Stream and Schitt Yagdrasil Analogue 2. We all agreed the Holo Spring was better in almost every way. I have a pretty good analogue setup and I prefer digital playback at this point. The I2s input is amazing on this DAC.
