Well I joined the Silversmith FIDELIUM Speaker cable club today

The story behind this goes like this. I bought new speakers in December and their placement forced me to stop using my Wireworld Gold Eclipse III bi wire cables because they were too short. So for an interim cable I found a 2 meter pair of the "Regular" Eclipse III wires used being that I wanted to keep it in the "Family." My  entire loom for the most part is Wireworld Gold Eclipse III interconnects.  The Reg Eclipse III seemed fine but I alway felt I was missing something I was used to before, like it was just a little veiled comparatively. I've researched the hell out of cables and was just going to get a set of the New Eclipse 8's but when they raised the price for a 2M pair another $500 to $2000 I decided to look elsewhere, scouring used cables for months.  Well through that process I discovered the many threads and positive reviews on the Silversmiths, so since they were more like what  I was hopefully  willing to spend I ordered a 6 foot set. Today I placed them into my system and after about one minute into the track I was astonished! I couldn't move from my chair, I listened to the entire album in astonishment. They literally "fixed" my system, it's never ever sounded this good. It's only been a few hours so i won't go into everything that happened right now but new cables are not  supposed to sound this good straight out of the box. I am lucky. they blend with my system right away. The Bass was so immediately impactful I just cannot believe a cable can make this much change, the inner detail and transparency, wow! I know these things have been raked over the coals in these forums and their are some that are naysayers, but in my case I was one of the lucky ones because these babies are not going back to Chris!  I cannot stop listening, it's amazing.



I popped over to their website out of curiosity. I don't there there is any way to determine the inductance as it would be conditional on how close or how far you kept the two conductors from each other. There width would negate some of the variability, but there will still be variability.

There is some contradiction in the statement below. I don't believe they have a metal alloy 33 times better than copper or silver (one does not exist), however, the claim below it compares it to a thickness of 5.5 times less. I don't see any particular benefit to a 0.00018 equivalent thickness of copper of silver. That is sufficient for about 200MHz back of envelope. It does sound impressive though. Any metal alloy with a skin depth of 5.5x that of copper or silver will unfortunately be a higher resistance alloy comparatively.

Since they are unlikely to have the resources to create their own alloy, I have to assume they are using something off the shelf. Monel and Constantan alloys are both up in the 5.5x range almost exactly and are Nickel/Copper alloys. However, they are really awful conductors. A pair of speaker cables could have resistance as much as 1 ohm. That would explain a unique sound.

FYI - materials science guy, semiconductors and batteries so this stuff is old hat for me.


The skin-effect characteristics of our state-of-the-art FIDELIUM alloy are up to 33 times superior to those of copper or silver.  The FIDELIUM speaker cable, already at less than a thousandth of an inch thick, performs as if it were 5.5 times thinner, thus experiencing less frequency dependent attenuation and phase distortion than even a .00018 inch thick copper or silver ribbon or 64 gauge wire.  

If you mean me, then no, I am quite sure that I read it quite correct. However, it contradicts itself which is not my fault.


the problem with the silversmith fidelium cables is there just so damn thin very easy to damage them or have them creased.
