Yes I went back and forth between the Carbon and CC however after several exchanges with him I also ended up with a "plain old" generic Carbon
How do you like the BiPolar? What appeals to me is the fact that it will internally convert a single ended source to balanced out. This is the main reason I did not go with the GSX and went with the Moon instead. My sources are not balanced out
Yeah I was also looking at the GS-X Mk2, but wouldn't get to make full use of it yet due to my single ended DAC. Justin told me the upcoming GS-1 revision would convert SE to bal, I tried to be patient but then saw the Pure BiPolar in Birgir's site and caved in. The rest is history!
I like it enough that I don't plan on buying any other dynamic headphone amps. Like the GS-X Mk2 it just gets out of the way and lets the headphone show what it is capable of. It will open up new dimensions to bass and separation/layering compared to most other amps.
The KGSSHV Carbon will likely be my last electrostatic amp too, and maybe my last headphone amp period.
