The Fabulous Silversmith Fidelium Speaker Cable
« on: 22 Sep 2020, 05:22 am »

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.
www.thesoundadvocate.com/2020/06/silver ... 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 soundstage would collapse and 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.

Thanks for your detailed review.  I ran into Jeff at breakfast at the Florida Audio Expo in February.  Waiting to get some painting done in rooms (pandemic has pushed it back a drop) and then I have to take a bunch of things apart, including the rack in the main system (put together without any components it weighs 350 lbs.).  So once that stuff gets done (hopefully around the end of the first quarter of next year, give or take, it's time to re-look at things (behind the main system is super difficult to get to so before everything gets back together it will be careful organizing).

Hi eichlerera1

Thanks for the great review. Sounds like you found the same sublime natural sound that I found. I'm one of those comments from satisfied customers on Jeff's Silversmith Audio site. Fideliums are an absolute steal and Jeff is great.

Become a Flat Earther in the world of cables  :lol:

Greetings @eichlerera1

I greatly appreciate your thoughtful and detailed feedback on the Fidelium cables.  Thanks for sharing!   I'm thrilled that they were able to enhance your enjoyment of your music!

The DECAY!  I couldn't agree more.  Though all the macro/micro dynamics, imaging/soundstage, transparency/resolution, etc. improvements are obvious as well, it's the Fidelium's ability to render the information between the notes that amazes me every time I turn on my system.

Happy listening!

There was a time long ago when I lusted after Silversmith Palladium cables but couldn't (wouldn't?) afford their price. 
If Fidelium cables are at least as good as Palladiums at a fraction of the price, that's certainly fantastic news for audiophiles  :thumb:

You won't be disappointed. I've been too lazy to develop a review of these. eich hit the high points.
My midrange bloat disappeared over the predecessor cables. And I play a bunch of piano music now!

Sure can! Note that the standalone Jumper Pic came from Jeff. The one I received was a bit more refined.

So the closer the two ribbons are to each other the more high frequency response. The farther apart the two ribbons are from each other the less high frequency response. Loudspeaker depend, of course.

Where do you get that info from?

This doesn't make any sense.
Please explain why.

At high frequencies, end-to-end cable inductance becomes more important.  The closer the two conductors are to each other, the lower this inductance.
This is more important with loudspeaker that have a low impedance at high frequencies (think Apogee and some ML speakers) and of course longer cables.

Yeah, but get them too close and you'll have far too much capacitance for some amps, which can result in instability and well, maybe some not so great things happening to your amp!  :lol:

IMO, you're better off with them separated by at least a few inches and then you'll get the single-wire inductance based on the dims of the foil. I will refrain from offering any opinion on this.  I'm just posting to keep folks from destroying amps.

Yep, those old legacy and boutique amps could get very unhappy with high total capacitance cables!
But separating the conductors of any cable or cord (be it speaker, interconnect, data or power) turns it into a great interference antenna!
The best speaker cables are of a twisted pair or quad construction.

Well, I guess I'll just ignore my lying ears and get me a pair of cables using traditional (read old) construction.
I got the Fideliums separated by a few inches and they are working just ginger peachy......
So just what is the inductance (or capacitance) of two Fidelium Cables, four inches apart, each lying flat with their <1/1000th of an inch edges facing each other? Hmm?
Yeah, I thought so.....

Speedskater offers good advice.  These cables will act like excellent antennas. In fact if you wanted on purpose to create an antenna in order to pick up stray signals and emi noise you probably couldn’t do better than these cables. So you should be very careful in locating and routing them based on what other cables, power supplies, and other electrical noise sources are nearby.

Folks, please keep responses informative, specific, and considerate.

Two other comments:
  • Remember that just because something works well in your system doesn't mean it will work equally well in other systems.  (You may have a cleaner local power grid than others, or you may live in an electromagnetically quiet region when others live next to a broadcast tower, or you may have a high sensitivity system where others have low sensitivity systems, etc.)
  • Unsupported generalities are less helpful than specific guidance or references with supporting context.  Similarly, explaining the "how" and "why" of something will better enable people to determine whether a limitation is actually relevant to their situation, or help them determine (potentially simple) mitigations.

Thank you.

The Fideliums is the most quiet cable I've ever owned....
I tried three different routing scenarios without a hint of noise from them.
