Clean up your power supply and get purer sound from your audio

We HiFi enthusiasts love to squeeze every ounce of performance out of our systems, whether it’s upgrading our speaker cable, improving the isolation of our speakers or even conditioning the electricity that powers our amplifiers, turntables and streamers. So throw away that cheap and nasty power strip and use something better to power your audio setup.

Atlas Cable is a specialist cable engineering company based in Kilmarnock, Scotland. I’ve reviewed the brand’s cables and interconnects before, and the company makes well-made, relatively affordable cables of every type imaginable. Some people spend crazy money on their audio cabling, but I often think it’s a matter of diminishing returns. However, wise investments in speaker cables, interconnects, and power wiring can improve sound.

Atlas Cables has now produced an affordable range of power distribution blocks called Eos Modular 2.5. The product has been designed to replace cheap multi-way power supplies that you might find on sale at a DIY store or your local supermarket. The Eos Modular 2.5 block is housed in an aluminum chassis and internally wired with 2.5 mm² copper conductors. High-quality wiring ensures unhindered power transmission between individual outlets with minimal resistive losses.

But why would you want to shell out more than a few dollars for a power distribution block? Granted, all a power supply does is provide power to your audio or home theater system… right? Wrong! Our homes are an electrically noisy soup that is overwhelmed with all kinds of interference from the various devices in our homes. Refrigerators are notoriously noisy when it comes to interfering with electrical circuits. The low-quality power distribution blocks and extension cords that many people use for their audio or home theater systems can contribute to reduced performance.

Some inexpensive power supplies have little or no shielding and often have noisy neon power indicators, fuse holders, and poor quality wiring or busbars, all of which are potential weak points. You can read about some of the issues here. The Eos 2.5 is a rugged, shielded power extender specifically designed and built to provide unhindered power to components in any audio setup or home theater system.

Housed in a highly conductive aluminum chassis, each Eos 2.5 power outlet is optimized for low contact resistance and minimal resistive losses. When used with Atlas Cables Eos dd, Eos 4dd or Eos Superior shielded mains cables, significant RFI shielding is achieved. Rubber studs or conical spikes also provide an additional level of isolation or mechanical coupling, in addition to an integrated wall mounting option.

A built-in direct earth drain path for interconnects and shielded cables includes Atlas Cables’ Grun Coherent Earth system which further reduces system noise floor, generally eliminating digital “glare” which is a typical symptom RFI/EMI noise degrading the audio signal.

If you want to get more out of your home entertainment system or TV and AVB receiver, be sure to clean up your power supply to eliminate hum and lack of focus in your system’s sound.
