There are plenty of cost effective dacs out there, that function they way that they are supposed to. Personally I would wait until the issues are fixed before purchasing one.
SQ is subjective and we all hear things differently. DSD is also subjective.
Have you looked at the stoner acoustics if you only require a dac? The new 120 is getting really positive feedback and is only 79 shipped, I just purchased one a few days ago and I am eager to receive it.
