In Reply to: A cord resonates at its fundamental and harmonics. posted by Al Sekela on February 15, 2007 at 09:56:02:
Al:"This means audiophiles can do simple things to improve their sound, by experimenting with non-audio equipment noise sources under their control."
This I like. If there is a point where we can start measuring stuff to connect the theory to practice then we're in business.
I am afraid that even if I study transmission line theory and known ways of reducing both induced and conducted RFI, I will be no closer to understanding the how's and why's of a lot of AC cable products.
Then again too, not all audiophile AC products are created equal. I am doubting that resonance issues were taken into account with cables that appear to be nothing more than shielded Belden wire in a fancy sheath.
Much to read and learn about here...
Thanks for your reponse.
Cheers,
Presto
