Since I was recently reminded that I hadn’t posted this yet, I received my Singxer SU-2 KTE about a week ago!
I could give impressions, but basically everything that other forum friends are saying in the dedicated thread is true (background, imaging, staging, etc). Though note that I’d also started off with some USB wonkiness from my Exogal DAC, so if anything, I might even be getting a little bit more of a boost than your average DAC pairing.
