want to ditch my Brooklyn to streamer..thoughts?

I basically second the others here.  I have the Mytek Manhattan and the Bluesound Node 2 and Vault 2.  There is no comparison between the DACs in the Mytek v. Bluesound isn’t even close, nor should it be.  The Manhatten is a dedicated DAC that goes for about 10 times the price of the combo Bluesound DAC-Streamer.  I’ve never heard the Brooklyn, but imagine the same applies.
btw, both the Brooklyn and the Bluesound will do MQA.
  Another factor is reliability.  Bluesound does updates very frequently, and many of them wind up disabling functionality.  In the 2+ years that I’ve had Bluesound, I would say that’s inoperable about 20% of the time.  In fact, I also had their Pulse Mini, which is an expensive glorified boom box, and it died completely on me last month.  The warranty is one year, and Bluesound has told me that I’m sol.  I’m not to impressed by the short life span of a $500 component that sat in my kitchen for two years without moving.
My Mytek hasn’t missed a beat

I had problems with both my Node2 and Vault2.  The whole system goes kablooie at once.  And I still haven’t heard back from my dealer about the Pulse Mini that died a year out of warranty.
  I am burning my discs to a Synology NAS that I am currently controlling with the Bluesound.  It works now but I hold my breath with each Bluesound Update.  Travis from Bluesound Tech Support and I are now best buddies.  Ultimately I’d like to get a Bryston BDP 3, but that will have to wait.
  Bluesound is an amazing bargain, when it works.  The Vault combines a ripper, storage, software player, DAC (MQA at that), for just over a grand.  At that price point, it’s perhaps unrealistic to expect flawless performance.
