Merlin Black Widow MK6 UK Mains Power Cable
This latest iteration of Merlin Black Widow MK6 UK Mains Power Cable prominently stands out with its innovative design to reduce electromagnetic and radio frequency interference, ensuring enhanced performance compared to its predecessors.
The Black Widow advances its design dynamics by drawing inspiration from the acclaimed Tarantula MK6. Key features include the 2.5 mm2 twisted high-purity copper main conductors, ensuring efficient current management. These conductors are coated with a premium-grade PE, which boasts a superior dielectric constant compared to the conventional PVC found in many power cables. The distinctive earth conductor harnesses a uni-lay construction, accompanied by a CCST conductive carbon screen and a cross-linked PE jacket infused with remarkable anti-electrostatic properties.
Delving deeper, the Black Widow employs natural cotton fillers and a specialised wrap to further mitigate microphonic noise. It also incorporates a double-thickness CCST conductive carbon screen with a drain wire for added shielding. The external jacket of the cable is no less remarkable. It integrates a proprietary compound, which aids in neutralising electrostatic energy within the cable, consequently reducing its accumulation in the entire system. Due to its robust construction and low-gauge conductors, and extensive shielding, it's best paired with heavier components such as mains conditioners, amplifiers, active speakers and other substantial equipment.

Merlin Black Widow v Merlin Tarantula MK6 power cable
The Merlin Black Widow is distinct from the Merlin Tarantula MK6 because it offers additional shielding through its double-thickness CCST carbon screen and an innovative compound designed to actively neutralise electrostatic energy, enhancing overall performance.
Contact Enhancer Option:
Future Shop suggests the DeoxIT Gold G-Series contact enhancer for an unparalleled connection. DeoxIT Gold offers a conditioning solution that heightens conductivity while delivering enduring protection on various metals when applied to your cable's plug contacts. Some of its advantages encompass:
- Elevated Conductivity
- Preserved Signal Quality
- Diminished Wear & Abrasion
- Prevention of Corrosion
- An Anti-Tarnishing Protective Layer
- Stabilisation of Metal Connections
- Minimised Arcing, RFI, and Sporadic Connections
Opt for this from the ‘Contact Enhancer’ menu, and our adept engineers will prep your cable connectors with the solution before dispatch.
Specification Options
- Merlin Black Widow MK6 UK - Fig8 Mains Cable
- Merlin Black Widow MK6 UK - IEC 10 Mains Cable
- This cable, while sturdy, remains flexible thanks to its rubberised polymer jacket.
Please note: Due to its sturdy construction with low-gauge conductors and comprehensive shielding, this cable is best suited for mains conditioners, amplifiers, active speakers, and other heavy equipment, as it might elevate lighter HiFi components.
About Merlin Cables 
Established in the early 2000s, Merlin Cables emerged with a singular mission: to deliver consistent, outstanding performance at an exceptional value. Guided by a distinct design philosophy, Merlin endeavours to minimise system noise, preserving the integrity of the original signal and allowing any audio system to shine at its optimum capacity.
Every product under the Merlin Cables banner embodies this philosophy. They universally employ high-purity copper as the conductor material, ensuring that as one navigates up the range, the performance characteristics remain consistent, only elevating in quality at each tier.
In an age where ambient noise is omnipresent and often compromises system performance, Merlin Cables stand out. Their designs deftly integrate superior materials, from high-purity copper to cross-linked polymer dielectrics and even custom noise-reducing compounds intrinsic to the materials. This harmonious blend minimises the detrimental impact of external noise on any system.
At Merlin, the pursuit of perfection is ceaseless. Despite receiving accolades and being hailed as best in class by independent reviewers, the drive to push the performance envelope remains unabated. However, change is never arbitrary. Modifications are only introduced when they offer tangible performance enhancements.
In conclusion, Merlin Cables isn’t just a brand; it’s a promise. A promise of custom-made cables, designed to exacting specifications, always pushing boundaries while staying rooted in its foundational principles of exceptional quality and value.

The Merlin Black Widow MK6 receives consistent praise for build quality, robust shielding, and audible sonic improvements including cleaner bass, reduced noise floor, and enhanced clarity across audio equipment. Customers report noticeable upgrades over standard supplied cables and competing products. However, a recurring and significant complaint is the cable's inflexibility and stiffness, which multiple reviewers note makes routing and positioning difficult behind components, with some preferring the older 2018 version's more malleable sleeve. Customer service from the retailer is consistently commended as excellent. A persistent negative theme across reviews is the cable's rigidity, which customers identify as a practical limitation despite acknowledging the build quality benefits.
The cable is very well made, although quite thick and stiff. Overall, a worthwhile upgrade and I’m happy with the purchase.
The noise floor has all but disappeared, and I hear a richer, tighter bass.
For this reason (only), I am giving it 4 stars; otherwise I would have given 5 stars. As always, top-notch service from Futureshop!
Great value. Prompt delivery in functional but effective packaging.
Music from my Kef LS60s is more powerful, detailed, transparent, and better all around! I am tempted to get another one for the secondary speaker, but I would also like the option of a burn-in period and a shorter, one-metre length, not shown on the order page.
Thank you.
It's better than the supplied power chord.
Fantastic cable and a slight improvement over my other Tarantula iterations. THIS CABLE DONT BEND EASY. Tarantula much more bend friendly.
Very pleased with the cables performance. 5 stars
Staff at FutureShop were incredible, very helpful and knowledgeable and give me great advice and time when I phone them. I would not go anywhere else now plus delivery is spot on as well. Thank you
