I'm creating a model, and getting a lot of fireflies. I've read that these can be caused by poor lighting and by low render samples, and can be reduced by clamping.
However, I've got 2 lamps going, and I don't want to keep adding lamps until I have no shadows. I'm using 500 samples. I tried 1000, didn't help. (Using cycles render). I've tried all combinations of setting direct and indirect clamping to 1. The last helps some, but not enough to justify the reduced picture quality.
Note the inside of the drive ring and the back of the radio antenna.

Thanks to Todd's suggestion below, I redid the render using Branched Path Tracing, and the result was much better. Only thing I changed was upping the samples to 250.
