Hey, I have this custom made headphone amp I got from a friend. He paid a couple hundred dollars for it from some random guy on eBay. I believe its some form of cmoy amp, and he got ripped off. Regardless of whether or not its a rip off, it was free for me. Obviously there arent any instructions, and no markings on the casing. My question is whether or not it would damage something to get the line in and line out mixed up? If so, is there a way to find out?

I can post crappy pictures from my phone if they will help.

I often get mine mixed up and it never seems to give any problems, you just dont hear anything
