I had the 150B for about a month and sent it back. Not because it was crap or anything, rather, I would use but 20% of it's capabilities so the extra cost wasn't worth it to me. I posted a thread in the Digital section that's more in depth.
If I was coming from a Bluesound or Sonos then it would have made more sense due to the significant jump in performance but vs. my Auralic it came down to how I would use it.
I hope you enjoy it!
