Newbie considering 3 streaming DAC/Servers

In that price range I’d add the Innuos Zen Mk3, which can be had used around $2500. 

I own a Brooklyn Bridge, but have no experience with either of the other units you mentioned.  The Mytek sounds superb. It's extremely quiet, and it's easy to use.  

I use it as a phono pre-amp, a DAC for the CD transport, a wireless TIDAL streamer, and a pre-amp/volume control for tube monoblocks from the XLR outputs and a 4-sub DBA from the RCA outputs.  It also has an excellent headphone amp.

I haven't gotten around to running an ethernet cable to it, because I'm getting ready to relocate the hifi to a new room.

Not sure how the MBB works with ROON...haven't subscribed yet.

volumizer ... Thank you for your response. I like what I read about the headphone amp on the Brooklyn Bridge. But I’ve also read in other threads that there are issues playing music from an attached USB drive. One of my major asks is the ability to play from local storage at full resolution for PCM and DSD, in addition to streaming services like Tidal.

soix ... Thank you for your response ... I've considered the Innuous Zen Mk3 and it's an attractive package with excellent reviews. And I may still go for it in the end. I am thinking about a DAC upgrade, however. I'm not really interested in ROON so good control software for the unit would be a bonus.

If you don’t use Roon then you will want a unit that can handle those different files on its own, sound good without jitter, have potential power supply upgrades down the road and have a solid trouble free user application. I would look at the best Lumin you can afford.

I would also give Roon the free trial period a go. It opens the door to other brands that don’t handle MQA or DSD on its own, like the Linn DSM line for example.
