Toxic Silver Widow 22 V2 / HEK V2 mini review
Introduction:
There's so many boutique cable makers to choose from! Last year I narrowed my search by going for a local UK one, ending up with the Toxic Silver Poison 26 awg cable for my "transportable" rig Sen HD600's, and I was delighted with the results of this thin-ish silver-with-a-bit-of-gold cable. So I returned to Toxic when looking for a more substantial cable for my main rig Hifiman HEK V2.
At Toxic's top end, the choice was between the litz silver-with-a-bit-of-gold Silver Widow 22 or 24 awg, or pure silver litz Hydra 22 or 18 awg. I felt the Hydra 18 would be too heavy for me, so it was finally between the Hydra 22 or SW 22. These were both just about the same price, £360 - £375 for 6 feet, so the decision was based solely on SQ. Now, some will know that adding even a small amount of gold to silver will proportionally significantly increase resistance, which in theory is not a good thing. But I go by the end results rather than technical specs, so I went along with Frank of Toxic's recommendations based on my brief, which in short was: no change in tonality, with more clarity and detail, without any hint of harshness. Frank recommended the SW to match my brief. I'm told the Hydra has potentially even more detail, but a leaner bass, so probably better suited to darker type headphones.
Then I had to wait for weeks and weeks and then more weeks (at least 12 in the end). It's just how it is - the website does warn about this. The good news is that during this wait, Toxic upgraded their SW to V2 status, which primarily was to make it more flexible. This turned out to be a good thing.
Unboxing and First impressions:
There’s no point in doing an Unboxing video unless you enjoy looking at Jiffy bags, but the cable itself looks gorgeous – and I'm not usually bothered by cable looks - all these naked silver intertwined cables look much the same to me. But this one is rather different:
Firstly, its insulation is much thinner than that of the Silver Poison, and almost disappears, giving the impression that you're looking at pure metal.
Secondly, its got a darker hue to it, which along with the litz construction gives a "vintage silver" appearance, rather like a Victorian silver necklace. You can see this effect in the final photo comparing SW to SP.
Thirdly, it really is very flexible, almost slinky, with a soft feel to the insulation. There is an option of an external black sheath, but I didn't go for that.
I did a weight comparison SW against the rubbery stock cable. Because my SW was 0.5 metres longer than the 3m stock, to be fair I weighed the stock cable without its big plug (result was 55 grams) and the SW not including 0.5m and big plug (result 95g). So the SW is almost twice the weight of the stock cable, but this merely reflects how featherweight the stock cable is. On its own, the SW does not feel heavy and is totally not cumbersome.
Sound Quality:
When I first heard the SW in my system, I had to check that I hadn't accidently turned the volume up a couple of dbs (I hadn't). Everything jumped out with greater dynamics and clarity. This
was from cold. I'm an impatient man, so I hate the idea of burn-in, but I've noticed it before, so I reluctantly left my system running over several nights before making final judgements. Now, whether it was cable burn-in or brain burn-in, I did feel that the SW did change up and down slightly over time. I didn't set a stopwatch to this, so my timings are extremely vague, but I reckon it took in the region of 200-300 hours to get to a point where one evening I went "Wow, this is it!".
In short, absolutely everything was better and absolutely nothing was worse. Any parameter you can think of. I listened mostly to off-mainstream female singer/songwriter types, but also to other genres including classical. It didn't matter if the recording was good/bad/bright/dull, they all benefited from the greater clarity, focus, detail and dynamics. And the increased levels of fine detail improved depth perception as well as countless examples of hearing little details I've never noticed before. Made it more like a live performance and less like background music. The overall level of improvement was easily the match for, say, a DAC or Amp upgrade.
Tonally, in some ways there was not much difference versus stock, but there were 3 characteristics that appeared to indirectly affect tonal perception:
Firstly, despite (or maybe because of) the extra fine detail, there was a slight reduction in upper frequency glare and hash that made brighter/congested recordings more pleasant to listen to.
Secondly, the extra clarity and dymamics increased the “presence” of recordings that already have high presence (e.g. closely miked female vocals with lots of reverb). This greater “presence” can sometimes come across as brighter. If this sounds partially contradictory to the 1st point then that’s because it is. Bright recordings never felt artificially smoothed down - they remained bright but in a better way.
Thirdly, in some ways the most impressive change: Bass appeared in places I previously had not known even existed. This gave the whole presentation a weightier foundation, which in turn increased the height of soundstage (I'm not sure why I always seem to hear bass notes at the bottom and high notes at the top of a soundstage). There, wasn’t any more bass in volume, it was just, tighter, with more texture and more precisely located.
I find that rapid switch A/B testing has its limitations. I did a bit of that too, but I much prefer the long term listening approach. After getting used to the SW sound for a few weeks, when I switched back to the stock cable, my first impression was that I must have accidently turned the volume down a couple of dbs (I hadn't). The whole soundstage, but particularly height and depth collapsed. And the bass became more of a one-note thud. My second impression was that the stock cable sounded not so bad on its own terms. A bit flat, bland, “thick” and uninvolving maybe, but pleasant and balanced enough - it didn't suddenly sound terrible. But then as the minutes went on, more and more I felt disconnected from the musical performance, and it wasn't long before I was compelled to switch the SW back in. Funny how you can be perfectly satisfied with any component - until you hear something better, and from then become utterly dissatisfied with the original.
Caveats:
As always, YMMV. My system is basically: Roon on W10 laptop to microRendu to DAVE DAC directly driving the headphones. With a touch of EQ to tame HEK’s lower treble peak, and DAVE’s cross-feed which I find obligatory for the HEK. The low-rent source could obviously be improved (I'm working on that), but the mR and a few other tweaks work wonders to give a surprisingly detailed and dynamic sound (compared to dedicated servers I've heard), but its not quite perfect yet. I could do with a touch more analoguey warmth to balance all that clarity. Whilst the SW has given me a big step up in overall performance, it won't cure all ills (no one component can), so I've still got work to do, primarily on the source.
One example relating to the SW’s impressive bass performance: One of my tweaks is a HRS DPX damping plate on my DAVE DAC. This improves bass performance and clarity in a similar way to the SW, albeit the HRS does it in a much more subtle way. But here’s the thing: if I take away that damping plate, the magnitude of bass improvement the SW brings seems that much less impressive. Now, most of you probably don’t have DAVE or a HRS damping plate, so you may not notice how impressive the SW bass is, but you will have other components with different strengths that may highlight different aspects of the SW.
Whilst all recordings benefited from the SW, the better recordings scaled higher, i.e. the difference between best and worst recordings increased. So going from a great recording to a poor one can initially be dissapointing. The trick I've found is to not listen to only good recordings for too long in succession. Mix it up a bit so that you don't get too spoilt.
Rivals:
A 3m (10ft) length of SW 22 costs about £550 plus options. Some rivals mentioned recently in this thread include the Dana Lazuli Reference at near double that price. And the DHC Prion at about 3 times the price of the Reference! That makes the Prion 6 times the price of the SW. Wow! And the Lavri Master Silver which costs less than the SW. I’d love to compare all these, but I’ll probably never get the chance, so I can’t say how any of these compare. What I
can say is that in the meantime I’d be happy to stick with the SW indefinitely, so I’ve completely stopped looking for any other cable.
