After experimenting quite a bit, I am convinced that silver, whether in the IC or the speaker cable, can help. The two things I have consistently noticed is 1) improved bass speed, and 2) improved musicality. Of course, including silver alone in a cable isn't all there is to making a cable that works well. I've had at least one (very expensive) silver cable I thought was horrible; but I do think in general silver is under-appreciated for what it can do for bass quality.
