Not at all. Nor am I saying they don’t matter at all.
At this year’s AXPONA I attended Galen Gaeris’ tech talk, where he explained how the engineering affects basic parameters for cables. It was well attended, including a very well known member of the audio press. At the end of the talk (which included the math behind how each of the three Iconoclast cables are different) the well known fellow - whose been in the business for decades - asked “which one would be the best for my system”? First, lovely guy that he is, the question at the end of that tech talk was a giveaway he really didn’t understand what was being said. Second, the answer he got from Galen Gaeris was “that’s not something I can tell you as I don’t know the reactive characteristics of the particular equipment you have, and even if I did it’s still a personal choice”. His recommendation was for the fellow to try all three and decide for himself. The poor fellow seemed a bit perplexed by that. Iconoclast claims only what’s stated in their technical papers, nothing more. The company flies under the usual audiophile radar, but a little searching will show two or three of the usual online characters having written about them.
I use what for me are the right cables in the right places. Some are Iconolclast, some are Audioquest Dragon, some are Purist Audio. There are others. They each fit best where they are to have my system perform the way it sounds best to me. No presumptive decisions made in advance without trying first. Seem fair enough? 🙂
