The Variants
We will be comparing the OFE and SPTPC variants of their speaker cables and all three variants of their RCA and XLR interconnects. First, let's take a look at how these cables measure.
One thing to note: Iconoclast actually measures each cable in a pair to ensure they're matched pairs. I don't know of any other cable company that does this.
Measurements
To keep the charts easier to on the eyes, I've averaged out the values within each pair. As you could see, independent of the type of copper used, they measured pretty damn close. Remember, the only difference is the actual wire.
From an objectivist's point of view, these cables should theoretically sound the same - or at least very close. Then again, there are some who believe all cables sound the same regardless (lol).
As it turns out, after weeks of listening tests we'd have to agree with Galen (and many others) about the audible differences between these cables. And these differences weren't subtle.
