I just received the OCK-2 and the build quality is high. Ill be using it with a Mutec MC3 +USB and Teac 701t. Waiting for cables , but using a generic bnc to the mutec for a few days. Build quality is high, I have been skeptical of most Chinese brands, often for good reason. There are products that have questionable build quality but not this.
I bought it after seeing some videos of Jay's CDTs and gave it a shot. It feels like a luxury product, hopefully it's reliable...
