Review: Deep Sounds Cables Silver Surfers

Posted by Amine Slimani on October 12, 2010 at 11:04 AM


I was contacted by Stuart (who had read some of my reviews) a few months ago in order to ask me if I were interested to write a review for his cables.After a few e-mail exchanges I came to understand that Stuart had a longstanding experience in the hi-fi world and in experimenting with different cables.


It took me a little more than expected to finish this particular review,not because there was a lack of interest, but rather because I received them as I was relocating to another city. At the same time, it was a good thing that Ikept them for so long as I had the chance to audition them in a few different configurations and over an extended period of time, which avoids the “wow effect” of a new component, where you might miss potential drawbacks in the first few days of auditioning.

Description of the cable:


The Deep Sounds Cables use very simple concept and no-nonsense materialsand construction.


I have had many discussions with Stuart regarding audio equipment ingeneral and cables more specifically, and it seems that we have reached the same conclusion regarding what is important when looking for an interconnect: the dielectric (Teflon, air, PE…) has a big effect on the overall sound of a cable. The best dielectric is the air, followed by Teflon.


Regarding the particular material being used, Stuart has a preference for Silver Plated Copper which he finds to combine the qualities of both silver and copper.

Personally, I don’t care about what particular material is being used as I think that it really depends on the skills of the cable designer.

Prior tolistening to Stuart’s cables, I had listened to 3 high performing cables that left me with very good impressions:

-        Silver Plated Copper: Hifi Cables & Cie Maat (500€for 0.5m)

-        Pure copper: Actinote Aria (800€ for 1m)

-        Pure Silver: Artisan Ultimate Silver Dream (200£ for0.5m)

While I could have lived with either of the cables cited above, my favorite one was the Ultimate Silver Dream … because it was the cheapest.


Experimenting with different interconnects taught me that there is no single way to achieve a transparent cable that induce very little loss to the signal: cables using multiple metals with heavy shielding can work as well as cables using single core conductors with no shielding and air dielectric.


Stuart sent me 2 iterations of his cable: A first one was a shielded SPC (Silver Plated Copper) cable I believe, and the second one was an unshielded SPC using Teflon/Air as dielectric. Both cables performed extremely well but I focused my attention (and review) on the second and probably the final iteration using SPC in loose Teflon tubing (i.e mainly air dielectric).

Stuart also told me that besides trying different shielding and conductor geometries, he also experimented with different RCA plugs. His final choice happened to be cheaper but more neutral than the Eichmann Bullets he was using previously. (He asked me to keep the brand of the RCA plugs confidential until he has time to finalize an accord with their makers).

Personally, since I have zero DIY skills, I have never experimented with different RCA plugs on the same cable. Whether it has an audible effect or not on the transmission of the audio signal, I can’t say. However, choosing a “good” RCA plug probably won’t hurt the signal.


Overall, Stuart’s choices on making the cable seem to be more about simplicity and cost effectiveness rather than creating yet another super expensive cable. That was one of the reasons I accepted reviewing his cables.

Note on burn-in and my testing method:


If my memory is correct, Stuart told me that the ICs he sent me had already been burned-in. So I cannot say if and how much burn-in they require.


If you look at other cables reviews and even manufacturers websites, you will see the notion of cable burn-in which will probably offend many people.

Some people might view it as yet another marketing scheme to push people to get accustomed to a product that is bad sounding at the first listen.

While I used to think the same, I have come to change my mind a little bit on the subject. Though I have noticed “burn-in” to various degrees with cables, Ithink it is different from the burn-in we are used to with other equipment such as headphones or speakers. I have noticed that most cables require a certain period before they “settle-in” in a new system. This makes quick A/B comparisons very difficult to make and pretty much worthless in my personal experience.

So, if I leave a cable unused for a longperiod of time, it usually sounds bad and if I start to quickly switch between cables, they start to all sound the same and … bad.


Of course, when comparing something like an entry level cable (KimberPBJ) with a top level cable (Ultimate Silver Dream, Deep Sounds SPS), the difference is perceptible but not to the extent of what you can hear in longterm listening.


When comparing cables or audio components in general, it is very important to make long term listening sessions. Contrary to what many expect from upgrading equipment, getting a higher grade component or cable provide with "less" rather than "more". You get less distortion, less noise, less high frequency hash, less listening fatigue and most importantly, you have to make less effort to reconstruct the recorded event.

When listening very hard, you can pretty much pick most details in any half decent hifi rig. However, the experience with a high-end rig is totally different: you can just sit and relax and let the representation unfold beforeyou with the least possible faults that constantly remind you that you arelistening to a recording and not live music.

In that regard, doing quick A/B tests does nothing at helping you distinguish what you might prefer on the long term listening.


So the review that follows is based on my subjective listening experience with the Deep Sounds Cables Silver Plated Surfers (official name) over a period of a few months. If you think that quick A/B tests are the only way to conduct a “proper” test, then you should discard everything I say below. If, on the other hand, you share a similar view, which that our hobby is aboutlong term listening, you might find what follows as a perspective on how these cables sounded in my system and to my ears. Your mileage may vary.


The sound:


Before reading this review, I encourage you to read my Artisan UltimateSilver Dream review as I make many references to that cable (i.e it is my reference cable).



Timber & Tonal balance:


The Deep Sounds Cables SPS have a very even and linear tonal balance throughout the frequency spectrum.

In comparison, the Ultimate Silver dream is slightly more sparkly in the highs and (slightly) warmer in the lower mids and upper bass.

But keep in mind that the differences between the two wires are very subtle and that extent of the difference is also dependant on the different equipment that are being connected. Weirdly enough, I heard a smaller difference in tonality on my reference amp, the C2, in comparison with the ST-3which has a lower resolution.


However, what is more important than a neutral macro balance(Bass/Mids/highs) is the way a cable or a component handles the timber ofinstruments.

Here, both cables are superb at preserving the natural timber ofunamplified instruments and voices and let you hear the true tonal color ofevery instrument/voice. Both are world class in that regard.


When using entry and mid level interconnects, you might often struggleto hear and recognize different instruments. Some cables are so coloured thatyou have to make some efforts to distinguish close sounding instruments when alot of things are happening in a large scale orchestra.

With the Deep Sounds SPS, you not only easily recognize differentinstruments but you start recognizing different brands of instruments.


In Concerto for Two violins, one of my favourite tracks to test thetimber of a component/cable, the two lead soloists (Carmignola and Mullova) use2 different high quality violins (a Stradivarius and a Guadagnini) and you caneasily hear the differences between the two. On many entry level cables, youdon’t even get a natural sounding violin. With the Deep Sounds SPS, as well asthe Ultimate Silver Dreams, you get to the point where you hear enoughsubtleties on the violin that you start hearing what specific violin is beingused.

Of course, it goes without saying that every element in the listening chain hasto be top notch to hear the superiority of the Deep Sounds SPS over run of themill RCA cables: You need to have an ultra low jitter transport, a veryresolving and natural sounding DAC, a very transparent headphone amp and exceptionalheadphones. When you remove even one element from the chain, you start hearingat best case scenario the two violins sounding similar and worst case the twoviolins sounding unnatural.

So while a cable can reveal hidden subtleties, it won’t create anything new.Best case scenario, it doesn’t hurt the signal and in most cases there is aloss in the signal being transmitted.


I could go on by using the usual words describing the bass quantity,bass quality, midrange... this cable is really beyond such a description.


Also, while I said previously that the Artisan Ultimate Silver Dream and theDeep Sounds SPS had different sonic signatures, keep in mind that therecordings will have far more impact on the sound signature of the system thanthe Deep Sounds SPS or the Ultimate Silver Dreams (that is assuming that therest of the chain has also low coloration).


Regarding the quality of the recordings, while you do not appreciate allthe timber subtleties that the Deep Sounds SPS is capable of until you play arecording that contain such subtleties (it is an obvious statement that getforgotten sometimes when evaluating equipment), it doesn’t mean that low graderecordings cannot be played over it. In fact, the poorer recordings I have playbetter on the Deep Sounds SPS than on low grade (fuzzy and falsely warm)interconnects. This is similar to what I have noticed with higher quality DACsfor example.


I have often read comments where people confuse “neutral” with bright,overly analytical and boring. The Deep Sound SPS is definitely not that type of“neutral”.


In my opinion, the term neutral means that the component doesn’t add orsubtract anything to the signal it is tasked to transmit. And that is exactlywhat this cable is about, absolute neutrality.



Soundstage & Imaging:


This is the area in which I had the most trouble identifying theproperties of the Deep Sounds Cables. The word that kept popping in mind tryingto describe this particular cable (soundstage wise) was “monitor like”.


Contrary to the Artisan Silver Dream which manages (in comparison) tosound consistently more open, the soundstage of the Deep Sounds SPS are moredependant on the recording itself. Once again, while there are a fewdifferences between the two, there are more alike than dissimilar.


Another thing that surprised me when listening to the Deep Sounds SPSwas that the imaging seemed at first too thin with my ALO recabled Beyer T1s.It was until I listened to a few high quality and high resolution recordings(such as Rachmaninoff Dances or Jazz at the Pawnshop) that understood totallywhat was happening. My system was not capturing the position of the instrumentrelative to the width, depth and height but it was also capturing the size ofthe instruments in that soundfield to an extent I have never experienced beforein my system. The Ultimate Silver Dreams are less precise and focused in thatregard and slightly inflate the size of the instruments.


When I sent for a few days (out of curiosity) the Ultimate Silver Dreamsto Stuart to get his opinion on them, he described them as hazy in his system.

In my system, I found that the imaging is not as focused as his SPSinterconnects, but I wouldn’t go as far as describing them as hazy (which has anegative connotation).

While the Deep Sounds SPS are the best imaging cables I have tried sofar, I would say that the Ultimate Silver Dreams are not too far behind. They“punch” in the same category I would say. On the other hand, other entry levelcables I had on hand such as the Kimber PBJs or the Sharkwire sound noticeablyinferior.


So, and to sum up, what to expect from the Deep Sound Cables in thesoundstaging department? Well, if your source has holographic qualities, itwill be passed on untouched to the amp, if the source has pinpoint imaging, itwill passed to the amp… etc. The Deep Sounds Cables won’t add or subtractanything in here.


I have also to admit that when I am not listening critically or if I amlistening to average recordings, I subjectively prefer the way the ArtisanUltimate Silver Dreams throw a big and airy soundstage (regardless of what isactually on the recording itself).




Some people might wonder how it is possible that a passive device suchas an interconnect cable might affect the dynamics.

I personally believe that the way a cable handle fast transients has abig effect on how perceive the dynamics. I could be right or wrong but this ishow I view things.


The Deep Sounds SPS is a very dynamic cable, which is pretty muchunsurprising for most good cables. It is indeed a quality that is shares withcables such as the Artisan Silver Dreams and the Hifi Cables & Cie Maat.

What is more interesting is that its dynamics seems to be spread evenlythroughout the frequency spectrum (which is a quality also share by the SilverPlated Copper Maat).


So what to expect in the dynamics department? The Deep Sounds Cableswill preserve the very fine tonal inflexions (micro-dynamics) but will surpriseyou by its thunderous power (macro-dynamics) when it is called upon.


Transparency & Definition:


If I had to choose one word, besides neutrality, to describe the DeepSounds SPS, it would be transparency.


Before writing this review, I tried the Deep Sounds in different configurationsand it seemed to me there was only one constant: the lack of sonic signature ofthe cable.

In comparison, the Artisan Silver Dream makes itself more apparent whenmoving it from one system to another. When using the Silver Dream, you getalways the impression that the soundstage is very open and that the highs arevery airy. No such thing with the Deep Sounds SPS.


The Deep Sounds are the more transparent to the recording (andassociated equipment) of the two and hence, should be used with equipment thatare relatively neutral (and musical) themselves.

As an example, while both the Deep Sounds SPS and the Ultimate SilverDream sounded pretty similar on the relatively neutral C2 amp, the ArtisanSilver Dream sounded far more open than the Deep Sounds SPS on the ST-3headphone amp.

If I didn’t know better, I would say that the Artisan Cable were moreopen (and more neutral), but having measured the ST-3 (which exhibits a bigroll off in the higher frequencies), and knowing the intent of the ST-3designer (which was to give it a tube like flavor), the Deep Sounds SPS were infact the most transparent of the two and passed the signal with the least editorializing.


In terms of raw resolution both cables play on equal grounds, whichmeans that they both are best I have heard from any cable I have tried so far.The more expensive Actinote Aria or the Golden Cross Cardas are no match interms of resolution.


If I were to make an analogy on the resolution department, I would saythat with lesser cables, you get the impression of watching a painting drawnwith a fat crayon, whereas with the Deep Sounds Cable, you get the impression ofwatching a high resolution picture printed on high quality paper. Whenlistening through the Deep Sounds, you have to make to very little effort todraw a believable scene in your head.


To sum up, I would describe the Deep Sounds Cable as highly transparentby giving you a picture of the event with a high contrast ratio.

In fact, if the associated equipment are good enough, you are notwatching the event from a transparent window, but you are at the event.


Note on musical examples:


When writing this review, I avoided (in purpose) making musical examplesbecause of the high transparency of the cables. If I were to describe how theDeep Sounds sounded on my reference tracks, I could have just copy pasted myimpressions on the review of the dac19dsp/C2 combo I used for most of thetesting.




The Deep Sounds SPS proved to be a very competent cable. It is perhapsthe best Interconnect cable (regardless of price) I have tried.


At the time, I am writing this conclusion, I have no idea what the finalpricing will be. But given how well it performed against my highly regarded andreference Artisan Ultimate Silver Dream, which is considered as a giant killeritself, I would say that the Deep Sounds SPS is probably going to be a highvalue cable itself.


If I were asked to recommend one cable for someone building theirsystem, I would say the following:

-        Pick the Artisan Ultimate Silver Dream cable if youwant to be listening to a relatively neutral cable that reminds you that youare listening to a very expensive and (slightly) sparkly cable;

-        Pick the Deep Sounds Cables if you want to belistening to no cable at all.





Side Note (that might interest Audio-gd owners):


I didn’t buy the Deep Sounds SPS review sample Stuart sent me but instead, I had him make me a custom ACSS Deep Sounds cable. There were mainly 2reasons for that:

-        I already have a reference RCA cable (the UltimateSilver Dream) which might not be as good as the Deep Sounds SPS on someparameters but I am very familiar with it, so no reason to get a second highperformance RCA interconnect;

-        My dac / headphone amps have 2 means of connection:the classical voltage RCA mode and the current ACSS mode. The ACSS connectionis more transparent than RCA (as it avoids a few conversion and buffer steps).

So my reference system now uses a custom ACSS/CAST cable made by Stuart.While the improvement brought over an entry level cable (Sharkwire in thiscase) is expectedly less audible on the ACSS mode, it was a definite andnoticeable upgrade nonetheless. The difference on long term listening wasobvious enough that it made the Sharkwire unlistenable: the loss of resolution,smearing of transients and frequency extension limitation at the extremes wereobvious. The only area where the ACSS Sharkwire beat the ACSS Deep Sounds SPSwas the size of the soundstage. On everything else the ACSS Deep Sounds wasbetter.

Stuart could you please let us know more about the evolution of this wonderful cable.
I am sure you spent a lot of time and that a lot of hard work and experimentation went into it.

your point about soundstaging I answered on headfi but it was deleted along with the whole thread - esta la vida.

Firstly let me say that it is incredible that two people so different in age should be able to hear the same thing - received wisdom says this cannot be - what again!

Your point about soundstaging is spot on. Completely irrelevant if you listen to say chamber music or acoustic singer/songwriter music but very relevant to orchestral works.

Is this a feature of SPC or the number of conductors I use - there is only one way to find out - empirical research.

I was unable to embark on this until I received more of the RCA plugs and the good news is that today I received a batch of the identical RCA plugs.

Amine has remarked on another thread and it needs saying LOUD AND CLEAR do not make more than one change at a time or you lose all your reference points and end up swanning around in the blue.

I will now experiment with using identical materials but less conductors - I use 4 x but now will try 2 x . I will soon know if the size of the soundstage is purely a function of the conductor material or not.

What I don't want to do is lose the 'immediacy' of the sound I have acheived, maybe 2 x will expand the soundstage at the expense of this immediacy and for some like Amine this maybe preferable, whereas others may prefer to suffer a smaller soundstage to be closer to the musician/singer.

Stavros - the journey was a little over 4 years but on the journey I learned a lot and I must publicly thank Tourmaline/Harry up there in Freisland for his incisive remarks and advice. I am hoping he will join the community here on Tweakfi.

I started out by using a low loss sat. cable available from Maplin and RS but regret not trying Teflon tubing much earlier. Teflon quite simply means a much more defined sound and more open.

I am surprised that the 'wrapped' copper of the ALO cable is so good for Amine with his Beyer T1 phones. Since using oversized teflon tubing has such a wonderful effect on the overall sound - I say effect because in reality it simply opens up the music. Wrapped wire simply does'nt do it for me, simple as that.

I have said that I will never get into a Mk1/2/3/4 etc and I meant it. Every year a 'new' model - come on chumps let me make money out of you each year. It maybe that using a different number of conductors say 2 instead of 4 will be different enough to offer 2 models for people who listen to different types of music. But as I have remarked to Amine I would love to try solid core silver/plated OCC copper. I have never seen any on offer and I very much doubt that a minimum order would be low enough to warrant an expensive trial in the material but I will investigate but that's it as far as material changes go.

I must repeat ad nauseum - replicating inside your amp the same configuration of signal wiring as the i/cs is something that has to be heard to be believed, this is what put the sheer joy of listening back into my music. I will offer this service to anyone who buys my cable. It will be very easy to acheive and should not be expensive. Most manufacturers route their signal wires around the inside edge of the amp, I suppose because it looks better. Much better to take the signal wiring directly in as straight a line as possible from signal input to pot/att.

That's about it at the moment.

Whilst posting on Headfi about how I would experiment with creating various digital cables to verify or otherwise that as a digital cable only has to conduct 1s & 0s perhaps any basic digital cable will do. I also posted that I would not be using any connectors, not that the recognized Canare a true 75 Ohm about ?16 per set are expensive but I did'nt want the connectors to get in the way of hearing what each conductor type was capable of - then came a moment of sartori.

Many Heasdfiers had asked me to build ACSS cables as Amine has. My reply was that I could'nt guarantee longevity of use because of the ACSS connectors construction.

However it came to me that the answer was very simple - don't use the connectors at all. If the chassis ACSS are screw fitted (please confirm this someone) then it is quite simple - remove them and solder the cables directly from DAC to amp. Quite simple really, just remove the DACs toplate, remove the chassis plugs and solder the wires appropriately. Then do likewise with the amp.

As you will not be constantly inserting and removing these ACSS cables there are no user problems at all. You can always use a piece of metal or plastic plate on the chassis with a large enough hole to take the cables and if you feel the need a rubber grommet to protect the cables but thhis really should'nt be nec.

Don't forget these ACSS connectors are nickel plated not the best metal for audio. I have already mentioned the benefits of using the same conductor/configuration inside the DAC/amp but this is even better - continuous runs.

Second best is for me to source these ACSS plugs and find some rubber or other synthetic tubing to allow me to use the Teflon tubing i/cs which are superior to the polyethelene dialectric that Amine has, then with adhesive lined heatshrink I can secure the whole and be sure of logevity of use.

I just wanted to correct a common misconception about digital audio. A digital spdif cable is not transmitting 0s and 1s. A spdif signal is transmitting analog square waves at very high frequencies (Megahertz range). The quality of the cable will affect the shape of the square wave and the way the digital receiver (in the DAC side) perceives those square waves. Basically, the better the cable, the cleaner/faster the square waves, the less guessing work the digital receiver (and the later down the road, the dac chip) and the less overall jitter. Jitter in digital cables is not only real and measurable but you can have different jitter measures depending on the direction of the cable (see for example:

To make a good digital cable that has repeatable and predictable results, one has to use a digital cable that is the closest to 75ohms throughout the length of the cable. Using the highest purity conductors and low less dielectrics will also help preserve the integrity of the signal and keep jitter low.
I believe that contrary to analog cables where people can fine tune by ears, it is imperative to follow some strict guidelines in constructing a good digital spdif. Or else, any digital cable developped in a specif system (with specific impedance mismatches) will only be guaranteed to work in that systems or accidentally comparable systems.

I just received my versions of the Deep Sounds cables and will give my review in two weeks and a few days!
