Hi mate, I bought the ZO2 (unboxed). The other amp underneath is my Ibasso P3+ (just for showing possible combinations)
C&C BH - Output 2, makes sense, seems a neutral throughput. Works really well out of 2 into the ZO2. Funny how you stumble across things rather than guidance, mids are pronounced via output 1 which you all probably know but finding a use for output 2 is also good to know.
There is just not enough time in the day but the C&C amp is versatile. Considering how sceptical I was, what a fun toy that doesn`t mind being bypassed (but still controls the volume)
