The best sounding music streamer/DAC on the market


Is it Aurender, Auralic, Lumin or something else? Interested in opinion of someone who carefully compared 2 or more models, comparable functionally, and price wise. The criterium is sound quality and musicality.

The latest Linn Klimax DS with Katalyst DAC architecture, latest Linn Akurate DS with Katalyst DAC architecture, PS Audio DirectStream DAC with Perfect Wave ll, MSB Select ll DAC with dual PSU, DCS Vivaldi full stacks, DCS Debusy & Rossini, Briscati DAC, Esoteric Grandioso full stacks, Naim Uniti Nova.

Unfortunately I didn’t have them both - U1 and S1 - at the same time, but I believe the S1 sounded better than the U1/Directstream DAC. I could be mistaken because ear witness testimony is unreliable with the passage of time.

I sold the S1 because I reasoned I could get a lower price Lumin and use my Directstream DAC and have as good or better sound than the S1and recoup some money I spent.  

At at the end of the day I’m happy with the U1 and Directstream DAC...but that S1 put a spell on me...
I had a Lumin S1.  Best I ever heard.  Sold it like an idiot to chase another audiophile dream...that didn’t work out.  Now have a Lumin U1 connected to a PS Audio Directstream DAC.  I think I’m happy again.
I have the Lumin A-1 with Tidal and a Synology NAS.  I love the Lumin App.  It is so easy to use.  You don't need JRiver or Roon.  I just added an EMM Lab DAC thinking my sound would substantially improve.  So far I am not hearing that much of an upgrade over the Lumin.  
1. Tuned amps, specifically Atma-Sphere
2. No streaming whatsoever, playing from portable hard disks only
3. iPad
Also, what streaming services do you want to use, and are you iPhone or Android?
Super personal though. Talk more about your preference of gear. Audio Research or Conrad Johnson? Which is you?
