Hi everyone,
I finished building the crack. Everything checks out with regard to resistance and voltage measurements. However, at some point, my gear setup was not complete as I probably did not connect the DAC to my PC, I don't really remember. Anyway, I plugged in my headphones (Senn HD 650), and there was nothing, as expected. After all, the setup was not complete. However, shortly after that, I started hearing scratching and popping sound. A few seconds later, the scratching sound got louder and louder until, suddenly, I heard a very LOUD popping sound. Then, there was nothing ... complete silence. I don't wanna talk about how I was grieving over my headphones because I thought it was damaged. That was pathetic. But I really thought the loud pop did something bad to my headphones and the only reason I had heard nothing was because my headphones stopped working. Thankfully, I tried my headphones on another device and it was fine. I also completed my setup and tried my headphones and they worked fine with the Crack. No problems so far; this is the Crack's second day. However, I still feel uncomfortable about what happened before and still worry that there might be a problem in my build which could appear again and deliver to my headphones the finishing blow this time.
So, would you please give me your opinion about what might have happened?
Best regards,
