Electrical Treatments

The mains supply entering your home is not clean. It carries noise from every device connected to it — from switching power supplies, dimmers, motors, and the wider grid itself. That noise finds its way into your audio equipment and raises the noise floor. The effect is not imaginary, and it is not trivial. It is one of the most consistent sources of degradation in an otherwise well-considered system.

At Martins Hi-Fi, we approach electrical treatment the same way we approach everything else: practically and honestly. Not every product in this category makes a meaningful difference. The ones we stock do.

Entreq

Entreq is our primary recommendation for electrical treatment. Their approach is grounded — literally — in the principle that noise needs somewhere to go. Entreq's grounding boxes, power distribution products, and signal cables are designed to drain electrical noise away from the signal path and into a controlled earth. The effect on the noise floor is consistent and, once heard, difficult to ignore. Low-level detail that was previously obscured becomes audible. Timing and imaging improve. The system sounds less like a reproduction and more like the event itself.

Entreq make products at multiple price points, from entry-level grounding solutions to their flagship Olympus and Apollo ranges. The right starting point depends on your system, your mains quality, and your priorities — and that is exactly the kind of conversation Dave, Chris, and Tim at our Norwich showroom are well placed to have with you.

We demonstrate Entreq in our own reference systems. If you are curious about what electrical treatment can do for your setup, come and hear it working in context. The difference is not subtle.
