By far, my most significant system upgrade!

I have always known how important speaker cables are.
So much so that I had spent $5K on my former cable.
But moved by slam dunk rave reviews and the knowledge of the integrity of designer, Jeff Silver, I bought his new masterpiece.
Amazingly, I spent a mere $1K and $275 on the bi wire and discovered a speaker cable that made my former cable sound like junk. Silversmith Fidelium!
He might have a touch of silver in his hair, but that's Jeff Smith you're referring to....

I agree 1000% with you assessment of this world class speaker cable!
No offence, but if you like these cables, effectively you like your high frequencies rolled off, but please don't move the cables, because every time you do, you have a completely different set of cables. They may be the most poorly thought out speaker cables every developed.

But sure, let's wrap it all up in what is effectively mumbo jumbo, making sweeping and meaningless statements about skin resistance while totally ignoring the far greater impact of inductance which will be all over the map because the spacing between the two conductors is not controlled.

However, if your speakers in your room are bright or you just prefer rolled off highs, these could be ideal tone controls for you.
The positive and negative legs of a speaker cable should be spaced closely to minimize inductance. Otherwise it is poor engineering!
I think it is highly likely that you two naysayers have never tried these out in your systems...
Financially low-risk for @dletch2 and @jasonbourne52 to try them out.  Go for it guys, or stop cluttering up the threads with all you profess to "know"

Their Returns Policy

Silversmith Audio offers a 30-day risk-free trial period during which the customer may return the order in like-new condition for a full refund, minus shipping charges.
Why would I try them out. I know how they will perform. I know that can be hard to comprehend, but I am sure you have expertise in an area that lets you state things off the top of your head that may not be obvious to others. The rules of physics don't have special cases for audio cables. They will be wickedly inductive, causing highs to roll off, perhaps even causing some additional resonance at crossover points. Every time I move them the performance will change. We can create a new term, NTSCT  -- Never the same cable twice.
Sorry Jeff Smith!
LPs that were truly unlistenable are now, not transformed into great recordings, but highly listenable. Inner detail and musical tone is now beautiful giving breath and depth formerly hidden.
And good recordings are now spooky good and breathtaking.
Surely, everything in a system is important and adds to the performance. But Filelium speaker cables doubled the perceived value of my system.

Also please note that the bi wires are $175 not $275!Jeff has created an innovative kind of jumper that, in a loop, connects to both sets of binding posts instead of a jumper that connects to one pair of binding posts and jumps to the second pair.
This seem like such a simple and obvious fix. But Jeff is the first to think of it and offer such a reasonable and logical improvement.
Is it really the case that the two conductors that make up the speaker cable are completely separate? That is pretty wacky given the inductance problems pointed out.

I've usually got an open mind about what will provide a positive benefit to an audio system, but this is right up there with using gallium alloys for speaker cable conductors - one of the worst electrical conductors that can still be considered a metal. 

These kinds of approaches which seem to ignore everything we've learned about physics and electro-magnetic behavior give audiophile products a bad reputation. 

I really wish cable manufacturers would, at the very least, list the capacitance, inductance, and resistance of their cables, even if they aren't willing to disclose the geometry and materials used.
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:

"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 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?


As I suspected, you never have auditioned them.
So you can predict how a cable sounds with no knowledge of it's parameters.
Very impressive!
You, my friend, are a blowhard....
