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.

Multiple reviewers highlight excellent value for money compared to premium alternatives like Chord power blocks. The safety switch is appreciated, and wall-mounting capability is mentioned favorably. Customer service from Futureshop receives universal praise, including same-day replacements and fast delivery. No significant negative themes or complaints were identified across the reviews.
Nicely built, solid block, and sounds much better than the Tacima I was using. Would recommend.
I consider this to be a good addition to my hifi setup.
Great service well done.
