Silversmith Audio Fidelium Cables

Greg Weaver said on his Youtube channel and on Enjoy the music that these cables beat anything he’s ever used at ANY price. I just ordered a set of 6’ for $995 US, I will advise when they arrive. Here’s his written review:
Here’s the Youtube review:

He says he’ll be they’ll be a lot of high end cables on Audiogon in the next few months. Will be interesting to see if they beat the Iconoclasts let alone the megabuck cables that are out there. Greg says they do.

I searched Hifishark for these and there was one speaker cable sold. Unfortunately they wrinkled really easily. Great idea but very fragile.

Looking forward to hear your thoughts on them.

I’m intrigued.

Another review of the Fidelium speaker cables.

Exactly! It is bad enough with cartridges and styli!

My pair of Fideliums came in today, talk about fast! Initial 30m impression is positive.

I’ll need a few weeks to burn in and swap back to the Iconoclast SPTPCs for a final comparison before leaving my impressions.

Not really sure how to arrange the cables, so I have positive and negative wires separated from each other.

A bit tough to avoid magnetic fields with these and they don’t seem to be acting like antennae.

My set of Fideliums are out for delivery. Using Kimber KS6063 since 2015. Let the swapping begin. Greg Weaver can attest to that!

If I like a product, I tend to hold onto it for a long time.
Take my stereo gear for instance.
I’ve had my Hales Signature System Two Speakers for almost 30 yrs.
I love the sound, imaging and soundstage they produce and I have no intention of ever letting them go.
The same situation is with my speaker cables; the venerable Straightwire Maestros. But in this case I knew that I would eventually upgrade them.
Both components have always been a tad bright, even with all-tube Amp, Pre Amp and CD Player on the front end.
After many years of constantly tweaking, I hit upon a combination which helped alleviate almost all of the glare.
Namely, a complete front end of ModWright products.

The only “problem” remaining was a time smearing element to the sound.
Fast piano and bass notes were not quite up to snuff in their separation.
Also, if I turned up the volume too much the sound would exhibit a bit of glare and the soundstage would tend to collapse.

I had long been a fan of Magnan products and currently use their interconnects and AC power cables in my system.
I’ve been looking for their speaker cable on the cheap for a while now.
I thought their approach to reducing skin effect signal doubling and phase issues would help in the articulation of fast consecutive notes (or sounds).
Plus I still had that tiny bit of brightness that needed a final taming.

I recently stumbled upon a glowing Sound Advocate review of the Silversmith Fidelium Speaker Cable. … st-review/
It actually was one of the finest cable reviews I had ever read.
There was great detail coupled with a ton of enthusiasm.
Like the Magnan, it utilized a thin ribbon to reduce skin effect anomalies. Plus, it used no termination products. (a BIG deal as far as I was concerned)
There were separate + and – leads for each speaker.
A “U” notch was cut into each cable end to interface with the Amp and Crossover.
I thought this was novel and highly desirable.
I called the owner, Jeff Smith and we discussed his cable at length.

One important item was that the Hales Speaker uses an external crossover with the capability to bi-wire.
This option was highly desirable to me so I broached this subject with Jeff.
He strongly recommended that I do so. Although not a deal breaker, the fact I would have to buy double the amount of cables was a bit of a concern.
Jeff replied two cable runs were not necessary and had a unique alternative configuration.
Namely, short Fidelium Crossover Jumpers with a simple but effective interconnect device right at the jumper’s midpoint where the long single speaker cable would connect.
His opinion was that this setup was as good as the traditional bi-wire method.
So just a 6’ set of speaker cables and a 1’ set of jumpers would be required.
I ordered the cables and patiently waited for their arrival.

Upon arrival, I was amazed at the light weight of them, which is understandable since the foil is less than 1/1000” thick and 2.25” wide.
The actual securing of the cables to an Amp or crossover binding post was a bit of a challenge, but not too bad.
The cable ends can be bent to fit into tight places, although there possibly are a few binding post configurations where connection would be very difficult.
Jeff told me that in a couple of months there would be finished adaptors available for those with fully plastic encased binding posts. He has been producing these adaptors by hand for those customers who needed them.

I turned on the system. No warm up.
Put my ear close to each driver. Absolute silence.
With no warmup, I slipped a CD into the player and listened.
The resultant sound was certainly very different than I was accustomed to.
Great detail but in a non fatiguing manner.
A beautifully balanced frequency spectrum.
Great Highs which were hash free.
Great tight Bass with accurate pitch and timbre.
Crisp, clear and sweet Mids.
Fast transient response, but not etched.
Very low noise floor. In fact, no noise at all.
I was excited that the Fideliums sounded so good with no system warmup.
With about an hour of warmup, I was ready for some serious listening.
All the attributes I previously heard were present but heightened.
The soundstage was deeper and wider than I had ever experienced.
The imaging was pretty incredible.
Each instrument could be easily localized and followed, without interference from another in the same proximity.
Really spooky!

But there was something else that REALLY set this cable apart from anything I had previously experienced.
The leading edge of each note (or sound) was wonderful, but it turns out the trailing edge and decay reproduction is incredibly super accurate. I mean SOTA!
IMO, this is the most important quality this cable possesses and sets it apart from all other speaker cables designs.
Distortions due to skin effect are vastly minimized.
Because of this, time smear/phase artifacts are virtually eliminated.
Fast piano and bass notes are truly distinct from each other.
Low level signals were readily discernable.
Echoes and decays of instruments was positively other worldly.

Because of these characteristics, I was able to turn the volume up to higher levels.
With my previous cables the sound would harden up if I pushed them too hard.
Fideliums showed no such problems.

In the editors comments from the Sound Advocate review, it was mentioned how accurately this speaker reproduced the sound of a piano. I can vouch for that. In spades.
The depth and power of the bass notes are just plain ridiculous.
And the highest treble notes have a real body to them, not thin and tinkly.
I would like to add brass, drums and percussion to the list of “scary real”.
And again, that decay…

In closing, the sound you’ll experience from the Fidelium will be totally different than you’re accustomed to. It’s kind of unnerving until you live with it a while. Nothing stands out. Everything is in perfect balance. It’s KILLER!

If you click on the Silversmith website there are numerous testimonials from other satisfied customers.
As you can deduce, I’m 100% sold on this product.
I cannot recommend Silversmith Fidelium Speaker Cables highly enough.


That was an interesting ad. A lot of claims for a pair of wires, which if true in your case, would suggest your old cables had poor synergy with your system. Have you heard them with anything other than your gear?

For a while I was running Morrow Audio Elite speaker cables, and these had separate positive and negative cables. I found that if they were laying directly on laminate-over-wood flooring, the sound was impaired compared to if they were laying on carpet. I ended up elevating them about 5 inches using hot drink paper cups I bought on Amazon. The sound dramatically improved.

When positive and negative cables are separate, I think the magnetic fields cannot cancel like they nearly will in a single bundle cable, so they can interact with things like nails in the flooring and maybe even dielectrics in the flooring materials.

The hot drink cup elevators are cheap and quick to try. I ended up spray painting mine a dark brown to blend in better with the flooring.



My Straightwire Maestros served me well for many years.
They were a bit bright and exhibited some time smear characteristics.
The Fidelium cable BURIED them.
I have not heard them in any other system.
But why take my word for it?
There’s a 30 day return policy.
Try em and you’ll buy em…

You’ve answered my questions, so all good. My Transparent References served me well for years as well, but time moved on. Lotta good cables out there these days.

What would come of using, say, 10 of these Fideliums connected simultaneously? Would it mess things up or would it allow for more current delivery?
Also… What are the benefits of a helix shaped ribbon, if any?

I wish I had the ability to just visualize the magnetic fields for a given geometry… Maybe I could if I used a physics modeling software long enough. They’re expensive, right.

A tweak that improved the sound: The Enacom Noise Filter (speaker type).
Placed across the speaker terminals (across the tweeter terminals if you bi-wire), I heard an improvement in the critical Upper Midrange/ Lower Treble response. Sweeter, but with added clarity.

Note: Do not attach this device between the Fidelium and the speaker post.
This defeats the purpose of the cable’s novel direct interconnect topology.
With my Edison Price terminal posts, I was able to jam the two Enacom leads into it’s open top, thus avoiding contacting the Fidelium itself.
If you don’t have this capability, I would recommend not doing it.

The Enacoms are pretty cheap on EBAY and as such are worth a shot.

It was noted recently how the Fidelium Cables sounded great on piano music. My Hales Signature Twos were once described by Robert Harley as having the most accurate portrayal of piano he had ever heard.
Well these two coupled together along with the two Reference Recordings of Minoru Nojima (Liszt and Ravel) was nothing short of scary…

This virtuoso only has about a half dozen recorded examples of his work.
These RR CDs are readily available on EBAY.
Scoop them up!


I had the recent pleasure of listening to the fidelium speaker cables on a pair of modified Tekton Moab speakers sitting on Townshend podiums, a PS Audio stellar gain cell and Bel Canto SET 40 (37w) triode amp. Jeff Smith, the owner of Fidelium, came all of the way to Seattle from Wyoming to audition for us. I’m not sure of the cables that we started with but they were no slouch and very expensive. The system sounded remarkable, especially given the total investment but when the Fideliums were swapped in everything became better. Smooth but crispy, more dynamic, and generally more coherent. The Bel Canto as well as the PS Audio were my pieces and I also own big Tektons, though they are custom, so my ear is pretty used to that source combo and the Fideliums complimented them very well. Jeff was a good guy to nerd with and his product performed incredibly, outperforming the much more expensive cables in every way except for convenience. They are a bit more challenging to deal with due to their shape but they’re more durable than the look. Just don’t fold then step on them and you should be good. I will be making my purchase after Jeff gets back to his office this week. Excited for sure. Would recommend.


Welcome, @thebrandonwade !

I switched from AQ to two pairs of Fidelium with adapters to bi-wire my speakers. Because their width and the way of connecting, I am using their adapters so the ends would not jammed and bent (for bi-wiring it is four wide cables per side). The sound is warmer, fuller and more three dimensional compared to the AQ RH speaker cables. They do need at least 100 hours of breaking in to sound better.

Hey! Thanks a lot!! I’m always willing to put in my .02 if it’s appropriate haha. This sounds like a good place for that.

People, kindly post more experiences of these cables.
