Another new DAC: Audio Mirror

While I wait on Vlad to get back to me on buying this DAC maybe someone with an AM SE can answer this question.

If the XLR option is selected will that result in a DAC with both RCA and XLR output. If so, are both outputs active? I will have 2 preamps on my office system (1 for headphones) and would like to hookup the AM SE to both pre amps. Of course, only 1 preamp would be turned on at any time.

BTW - is email the best way to contact Vlad?

I am new to tubes. This DAC will be the first one I have owned from the dark side. I was wondering how one knows when to replace the tubes?

@tvad Great thanks for that info.

I just bought the Benchmark DAC3B (again) and will buy the AM SE if I can find someone to sell me one (anyone, Vlad?).

I bought a CODA CSib integrated amp a few days ago which will be function as headphone amp for RAAL SR1a. The AM SE is for the bright RAAL's with the CODA but I would like to also use the AM SE with my speakers connected to an all Benchmark stack. 

I want to have both the DAC3B and AM SE connected to the Benchmark HPA4 preamp which should offer quite the contrast. So based on your answer I can do this.
