Pass Labs or Devialet

Pass labs.  No contest

Pass, of course.
I've heard Devialet on a few occasions and never really liked the sound. Actually it sounds pretty bad. 

I have said this before Pass Labs will work on almost any equipment that they  have ever manufactured. Some of the Best customer service in the industry fixed right the first time.  I have also had the same service from PS Audio from Paul, his son Scott and any employee that picks up the phone. It's all about AFTER the sale even on used gear. They answer email promptly even on general questions. Purchased the top of the AV receiver 8805 that had big issues at less than a year, it took 5 phone calls just to get a callback and that was the rep calling because I just gave up. Purchased an Arcam 860 so far so good.
Does the company care about their product or just making money. If you make a fantastic product at a good price you should stand behind it theses companies do!! More than just a name on a box

FWIW, I've made the final choices for my amp and source.

After a full day of integrated amp auditions, Pass Labs int 250, MSB ADC V Discrete DAC/streamer with second power supply, and the base Roon. Should be all set. Will order everything January 2, 2020. Can't wait.

  i vote American made Pass Labs i won't even read all that 
let's get that right
