Fidelium speaker cables are the most significant system upgrade of our system too. This is over 30 years of building the system. mrs. xenolith thinks so too.
So does another Audiogoner who contacted me about these cables and who, out of courtesy, since I haven't asked and he hasn't told me I can use his name, I'll leave anonymous. Here's an excerpt from his last message to me:
"I got my pair the other day. WOW!
Simply amazing. Best 1200 bucks I've ever spent on audio gear. A REAL upgrade."
Regarding inductance: from Jeff Smith, copied from here:
https://www.audiocircle.com/index.php?topic=172528.20"Likewise, if a user were to separate the positive and negative Fidelium run by a foot or more, the resulting inductance would still be at least 2 to 3 orders of magnitude less than anything that would affect frequency response."
I hear much better high frequency response...as well as every other frequency response...with the Fidelium cables than I did with the more expensive silver speaker cables that they replaced...and which they reduced my estimation of (on a scale of 1 to 10) from a 9.5 to a 5.
I would encourage my Audiogoner colleagues to be not so confident in what you would hear if you we're to listen to something and rather give some small measure of credence to your fellow Audiogoners who have actually heard that something.
Lastly, like I told the anonymous Audiogoner: "
Easiest way I can think of to be a hero with one's wife! ;)"
Who's not interested in that?
