Apparently a run of bad luck for me...

Today I walked past my system and heard static, even though everything was turned off. I isolated it to my DSP33C. I unplugged for a while, and the sound was still there when I turned it back on. I fed some sound through it, and the output was loud and distorted, static still present.

I swapped out with my left DSP33, static still there. By swapping speakers only, I eliminated a cable problem.

So, is my DSP33C toast?
