subwoofer IC's, silver or no silver content

I have the Nordost Baseline made to Rel specs. Yes they are silver PLATED solid core copper (6 24awg wires). Honestly I upgraded my standard Rel cable (aluminum) and the difference was unbelievable. Not puncher bass but a more believable bass. A ton more detail. I even had to cross over at a lower freq and turn down the gain just a hair. So does silver have an advantage over just copper? Can't say from experience but silver is more conductive than copper. That being said typically the electron flow is just on the first few microns of the surface of the conductor with the exception of low frequencies. They tend to ride in the center of the conductor. So your professional expert has a good point in theory. Theory does not always make sense in this hobby. Someday I may try a copper cable but for now I couldn't be happier with what I have.

Sorry I didn't answer you question but I just wanted to share what I know from my own experience.

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.

I just posted a thread ("A Great Subwoofer Cable") relating some of my experiences, check it out.
