I was at CanJam NYC this year and spent about 30 minutes listening to the Brooklyn DAC+. I was really impressed and paid for one right then and there and picked it up from Mytek's Brooklyn office a few days later. I'm still fairly new to the audiophile world so this was a substantial upgrade from what I was originally using, an Apogee Groove. What really impresses me about the B+ is how resolving it is. Using my benchmark set of tracks, I noticed new details that the Groove definitely didn't pick up. On top of that, something I didn't pick up on until a few hours of listening was that I was listening for a few hours! The sound wasn't fatiguing at all. With the Groove, I took regular breaks -- my ears just needed a rest.
I'm listening with a pair of Audeze LCD-XCs single-ended. I'm still burning my B+ in but still amazing so far. I had posted much earlier in the thread about concerns I had about the original Brooklyn, and I'm happy to say I haven't had a single issue. I'm looking into getting a headphone cable custom made that has dual 1/4" jacks 'baked' into it (I don't want the bulk/length of an adapter), an Sbooster (which seems to be out of stock everywhere at the moment), and a Curious cable. Going to take it one step at a time!
Overall I'm very happy with the the B+!
