Lumin A-1 or Lumin U1

Thanks for the reviews so far.  Another component has come up...Esoteric N05.  Supposedly very similar to Lumin.  There are so many choices out there right now.  

After spending about an hour with Dave from Audio Doctor, I have decided to buy the Lumin A1.  Dave really took the time to answer everyone of my questions and provided me with more information than I could have ever asked for.  Thanks Dave.  At the end of the day, I considered, PS Audio, T&A DAC 8, Auralic, Aurender, Sim Audio 380D, Mytek Manhattan and Brooklyn, Schitt, Bricasti M-1 to name a few.  I really wanted to simplify and that is why I wanted the one box DAC/Streamer.  This should go great with my Raven Integrated MK2 Reflection tube amp and my Wilson Audio Duette 2 speakers.  

I absolutely loved my Lumin A-1.  I thought the App was incredibly easy to use.  The sound echoed Rickray's sentiments.  That said I am just in the process of upgrading to a Laufner Teknik.  If I don't like it I am definitely going to go back to the Lumin.  My Lumin A-1 will be on Audiogon in the next week or so.
