I am looking for a clean, detailed, fast and transparent 'small form factor' dongle.
I do like the Cobalt in that sense, it seems to be the closest signature to my liking.
The xDuoo Link2 Bal seems a little soft and dull, but well balanced.
The iBasso DC05 is a maybe a bit too aggressive, non organic, non flowing.
CX Pro is not bad for the price, but is not as clean of sound and not as detailed.
I ordered a TT Sonata HD II ES9270, but it was DOA and had to return it.
All IMO of course.
I would rather not have to go to a larger form factor such as the Mojo, but would if I had to. I'm considering the Questyle M12, M15, Hidizs S9 Pro, or ?
@OspreyAndy's thoughts on the implementation of the ESS ES9038Q2M in the Cobalt was that it was a bit lacking. Maybe if that chip were in a better designed dongle it would be worthier?
