what did I do? channel hiss in McCormack DNA 0.5.

I was swapping preamps with the DNA 0.5, got a loud noise, and now there is an audible hiss from the left channel. I hear it on soft music or when I'm not playing anything. I don't hear it on louder stuff. Then, the music sounds great! I don't know what I did, but I know I wasn't careful. What's it sound like the problem could be? What should I do to find out/ fix it? Can I do any troubleshooting on my own, or is it best left to the pros?

Thanks,

Robert

Robert you've definitely done some damage but it's not real serious since the amp still plays. Definitely contact Steve McCormack & get the amp to him for repair. While you're at it you might consider an upgrade: SMC Audio has 3 levels of upgrades available. Check these out at his website & then talk to the guys at SMC; really good people there.
