Not insignificant per se....

Jon:

Not really. I am moreso suggesting that if things like trapping RFI, keeping out EMI, and minimizing inductance is important (and let's say they all are for the sake of this post) then why is it the 6 foot cord that gets the most attention? Is it the worst cable method of all the ones in place? Or just the most convenient one to experiment with, as I suggested?

Keeping out EMI is a no-brainer. Even with proper grounding, why put 60Hz fields near signal sources?

RFI resonances *do* appear to have merit from an engineering standpoint (transmission line theory), but you said something in that article that caught my eye:

"Reduced levels of induced RFI and radiated EMI/hum fields would not hurt SOTA sound reproduction."

Okay, these guys (Sean and J. Neutron) are differentiating between induced and conducted RFI, and there are different bandwidths for those kinds of interference. But your statement makes me wonder. Do we do things in audio beacuse they won't hurt? Or because they actually help? I can do 1,000,000 things that don't hurt - but they're all FREE! I don't think doing things simply to be "on the safe side" is good engineering, and it opens the door for products that "might do something" that we all need to use - to be safe.

I've read soooooo much about cable theory in the past few days I truthfully need to give your article a much better read. (There is a lot there to process Jon). I just liked your concept of what constitutes a "sane model" for looking at this. I do plan to read and digest as many references as I can. The theory alone here is not for the faint of mathmatical heart!

But you must admit: building the "perfect cable" that rejects RFI is amazing. But putting it in the same circuit as wiring that could very well be an "RFI magnet" (and inductive nightmare) does not make sense to me.

And we all know of quite of few guys who put special wiring back to the panel (and even better quality breakers) when renovating or building custom audio rooms.

So? Are these guys on the right track? Or did they just need a better AC cord or two? A couple grand for two good AC cables compared to tearing into walls? I can see the attraction and empathize.

Cheers,
Presto
