Black Octagon BOS2 Cable : The Tiny Upgrade that We often Forgot

Black Octagon Bos2 arrived Earmass!

Black Octagon Bos2 arrived Earmass!

Founder of Black Octagon Solutions  has sent me this BOS2 cable (3.5mm to 3.5mm,male to male),which is a wonderful creation from its company tome for reviewing purpose, special thanks for him for the wonderful cable,and attempt to bring good cable for reasonable price.

Back when I started this audiophile hobby, I already understand that good cable will lead to somehow better audio quality and cleanliness of the sound,but I have never encountered any with my headphone setup, the last time that I feel that importance of the cord and cable is back to my secondary school,when I change the copper cable to silver cable for my low end Hifi component,the changes of sound is really huge and big to be noticed. Till now, I still remembered how I am in love with the Audioquest Sky interconnect cable few years back.

How do you think its look? Honestly,I am loving it!

However when I am into this headfi hobby,I thought that cable changes is only vital for the headphone cable,I know that the cable connected from Dac to amplifier can be alter the sound quality,but never thought that it will be that important, I thought it is just subtle changes. So instead of purchasing a good interconnect cable, I use the Isimple 3.5mm to 3.5mm (Male to male) cable,which i get for free when I bought something from a guy last time.

Description and Design

Rean plug

Rean plug

Bos2 is selling for RM25-35(9USD),depend on your length and requirement. Price wise it sit in budget audio cable which directly compete with those DIY cable and supermarket cable.

So enough earful statement and history, so this is not a factory or wide marketed products,so even after you google search for it,you won’t be getting any useful information regarding this cable. So I will just quote what the founder said in personal message to me:

Ok details, the connectors are Neutrik/REAN NYS231BG, BG means Black (body) Gold (contact plating). It is the same as the usual NYS231 nickel plated plugs that Neutrik/REAN makes.The cable inside is Canare L-2B2AT. I’m sure you’ve seen and heard this cable before.  When it comes to signal cables or interconnects, I put a lot of emphasis on shielding. The L-2B2AT comes with a foil shield around the two signal cables and the ground wire. Most other cables use the ground wire for shielding.Ok, let me tell you a bit about Black Octagon’s approach to cables. Its shielding, shielding and more shielding! Yes, the Van Damme cables we use are ultra pure OFC and silver plated but the reason why I chose the L-2B2AT for the BOS2 is because of the foil shield. When I was designing the BOS2, I had two cable choices, the L-2B2AT or the L-2T2S. The L-2T2S uses thicker cores but it also uses the ground wire as the shield. Hence I chose the L-2B2AT. smile.gif 100% foil shielding.The other cables I use for other applications also share the shielding as the most important part of the construction of the cables. The Gotham cables have double Reussen shielding. The Van Damme RCA cables come with silver plated ultra pure OFC for the core and uses the ground wire as the main shield, but the core is covered by teflon and the teflon is covered by a black conductive material which combines with the ground that shields the core which keeps the core completely isolated.I can go on and on about the other cables I do but I’ll come back to the BOS2. The cable is soldered with industrial solder. The braiding is put on with heat shrink which is shrunk using a heat gun. Cables are tested before being shipped and all cables come with a very light coat of contact cleaner on the plugs so they remain clean when they reach their new owner. If you find the connectors a bit oily, just wipe it with a tissue paper. smile.gifBurn in should be about 20-30 hours but I expect the BOS2 to outperform your normal supermarket cables from the time you plug it in. -Black Octagon Solution

'Clothes' cable

‘Clothes’ cable

Ya,shielding is really important. After reading his message,I go and did some research,after reading some books and what I have saw last time in the magazine,I agree what Black Octagon said,shielding is one of the most important things for cable,and quite often people forgot about shielding and put more emphasise on the plug and cable material,which is what consumers wanted to. Same case in Digital camera world where manufacturer tend to produce higher and higher megapixels in thier consumer camera lineup,they would not care the image quality as long as consumer like,but think back,why do their higher end line up of pocket digital camera has lesser megapixel when compared to their budget line? Because they produced a product that will making money,what consumer ‘thought’ is good,advertised the megapixel specification,but forgot all other important things like image stabelliser, and noise control. They avoid the myth of megapixels. Same goes to audio world.

Hooked it up with portable setup,and you are good to go. It is a essential thing that needed for portable setup.

Okay,enough for the craps. So I have noticed that the plug is really tight when stay inside the jack which is a good thing,ensure good connection. So what Black Octagon told me regarding the shielding?

About shielding. I noticed people on here like to strip cables and take out the main conductors but why would manufacturers like Gotham, Canare, Van Damme and all spend so much on R&D for shielding and then promote it? Interferance causes noise. We humans cannot pick up the noise but we can ‘sense’ its there. We call it dirty, harsh…whatever la but its there in the background. Shielding eliminates noise thus producing a cleaner sound in most of the frequency’s we hear. Combine good shielding with a great core conductor and you got a great cable. Example, Gotham’s GAC2. Double Reussen shielding. The shielding is so thick, double copper. The inner conductors are very soft. But the cable is used in recording studios all over Europe cause its very neutral. Neutral meaning no noise and doesn’t color the sound. Same goes for Van Damme cables. Great shielding, good price.  – Black Octagon Solution

Design wise,Bos2 is really beautiful,shielded by cloth cable. Bos 2 is easy to bend and it is better looking than my Isimple and supermarket cable.Plug is nicely terminated and the hand work is neat. Said,I am satisfied with the price and outlook even without really listening to it.

Sound Change?

Bezo 3.5mm to 3.5mm(Male to Male) cable,which is what I bought at a local Pc store.

Bezo 3.5mm to 3.5mm(Male to Male) cable,which is what I bought at a local Pc store.

Bos2 was connected to Jds Labs Objective 2 amp and Govibe Minibox amp from Stoner Audio UD100 and Hippo Biscuit. Tested with Shure Se425,Creative Aurvana Live!,Bowers and Wilkins P3 and Yamaha Eph-100.

I have compared this to my Isimple and a normal cable (Bezo brand) that selling at Pc shop. To be fair,both of the cable’s length is longer than the Bos2,but should be not a big deal.

When I first plug this thing into my amp and Dac,my first impression is clean,clean and clean. It is really clean,sound is effortless and clarity is better,all of these without ABing.

Isimple 3.5mm to 3.5mm cable (Male to Male),which is 20USD,cost about 80% more than Bos2.

Isimple 3.5mm to 3.5mm cable (Male to Male),which is 20USD,cost about 80% more than Bos2.

When I ABing them together, the Bezo cable is simply out of the battle when I started to play the very first song. Bezo cable has too much grain in the sound especially vocal,making the overall sound too ‘heavy’ and rough.

Three cable side by side.

Three cable side by side.

Side to side compared with Isimple,honestly Bos2 win hands down. I can clearly heard that Bos2 has cleanest and clearest sound among the competitors,besides,Bos2 also has the best instrument separation when compared to Bezo and Isimple cable. All of the differences are quite obvious.

I tested with Paganini for two and Stradivarius the sunrise album. The differences are obvious.

*Test the original included cable for Hippo and Govibe headphone amplifier,when directly compared to BOS2,they lost in terms of clarity,cleanliness,bass response,vocal and overall sound signature. This is just a 30 seconds comparison but the distinction is indeed very clear.

Conclusion

It is a great cable!

It is a great cable!

Good : Clean sound,Better than those probably you can get in this price point, Beautiful and quality looking,Build quality,Customiseable length.

Black Octagon Bos2

Bad : Sorry but can’t find any for this price range.

The cable is cool,when compared to Bezo and Isimple.

So I am really impressed by the performance of Bos2,and I am really wonder how will be the higher end cable sounded from Black Octagon. Black octagon is relatively new but the company is actually long time related in the field already.

So you are not only buying any product from big company,Black Octagon really has good attitude and good after sales service. I am not sure though will them sell this cable worldwide but I have requested founder to give me his contact details as showed below:

Call, SMS or Whatsapp: +6 016 206 8974

The job is neatly done

I am not advertising  nor I have been paid by Black Octagon to write up this review,but Bos2 seriously worth my every words to recommended to.

You can bend it smoothly

if you never update your cable,and you really like your current set up,thinking that it still lack something,give it the last breathe (Upgrade your cable),maybe you  will be getting what you want.

Enough said! It is highly recommended!

    • I have sold the cable(The one come with Hippo or Govibe amp,so can’t comment on those. But clearly,the original one from Jaben simply no match when compared with Bos2.

    • Hi,

      I have tested Bos 2 vs the original cable from Hippo/Govibe,simply no matc. From vocal,bass to overall sound signature/clarity,Bos2 wins hands down.

  1. Hey guys, first gotta say thank you to Su for the review on the BOS2. As for Alan, as much confidence as Su has on the BOS2, please do keep in mind that the BOS2 is meant to be an upgrade over a standard cable. How it will perform against the BTG, goldring and starquad, I don’t know. Also how it will perform against a RM499 cable from J*ben…hmm…I got something coming up in the next few months for that, not gonna put a RM35 IC against a RM399 or 499 IC 😉

    As for the Canare F12/starquad combo and IC’s in that price range, the BOS1 is in that price range. As Su says, we place great importance on shielding and the BOS1 comes with double Reussen shielding and a choice of Canare f12 or Switchcraft 35HDBAU plugs. 🙂
