Atlas EOS Modular 4.0 Six-Way Mains Distribution System – Review

Atlas EOS Modular 4.0 Six-Way Mains Distribution System – Review


With my Naim NAC-N 272 and NAP 250 the EOS Modular 4.0 Six-Way delivers real audio improvement for my system and I would not hesitate to recommend the upgrade to those who have the means to invest in their HiFi

Atlas Cables has launched the EOS Modular 4.0 Six-Way Power Mains Distribution Block for higher end HiFi products. It is a mouthful but in the modern Olympic world of marginal gains for improved high end performance, Atlas Cables appears to have delivered an advantage in power mains distribution. I have always wondered how I could afford a cleaner power source because many of the products I have (Naim principally) require thousands to improve power quality, now I may have found a more affordable option.

You’ll need a mains cable too

EOS Modular 4.0 Six-Way Design

The EOS Modular 4.0 Six-Way Mains Distribution Block presents electrical filtering as a way of eradicating the unwanted interference that can cause degradation to the power supply for higher end systems.  However, not all audio products benefit from filtering, which is why Atlas has conceived the EOS Modular 4.0 Six-Way.  Now, you can choose which of your products can benefit from electronic filtering (normally those which carry low-voltage and sensitive signals such as turntables, streamers, DACs and pre-amps) and those which don’t (power amplifiers have dynamic power needs and many can be constrained when filters are applied).  With the EOS Modular 4.0 Six-Way, users can specify which sockets are filtered and which are not, allowing for total flexibility and matched outlets per component in their system.

Internally wired with Atlas EOS 4 dd PTFE power cable (4mm2), matched power transmission between individual socket outlets and the incoming mains supply is ensured, when mated with Atlas EOS 4dd screened power cable from the wall socket. When Atlas Eos or Eos 4dd screened mains cables are used to power all system components from the EOS Modular 4.0, significant air-bound RF screening is achieved.

Housed in an effective steel RF enclosure, all components have been sourced to be of the highest quality available, with the filtering circuit board being of heavy-duty design with gold-plated connections. Atlas uses a technique called Atlas ssd (Sequential Socket Decoupling) to ensure that even those sockets which are not subjected to inline filtration, enjoy a level of interference-free operation. The sophisticated filtering techniques designed by Atlas have been incorporated to remove unwanted RF energy directly to the three dedicated filtered outlet sockets therefore removing unwanted artefacts.

The Atlas Cables EOS Modular 4.0 mains unit is available now and can be specified as 6 x unfiltered or 3 x filtered + 3 x unfiltered outlets. A ground binding post is fitted to all models.  It is quite hefty too.

Performance

Increased roundness and wider presentation are very clearly evident here, and there is a further enhancement to my low end, it is really smooth

I have tried this EOS Modular 4.0 Six-Way in two higher end set-ups with some review equipment I have.  Using an Atlas Cables EOS Power Cable into the EOS Modular 4.0 Six-Way Block I have three filtered and three un-filtered power sockets to choose from.

Set-Up 1

EOS Modular 4.0 Six-Way

With Moon and T+A Electronics

I have hooked up the T+A DAC 8 and the Moon Neo MiND Networked streamer to the filtered supply and the T+A AMP 8 (a power amplifier) to the unfiltered supply.  Overall the system performs beautifully, the Moon streamer is clean and wholly functional.  Is there a gain? I think so, the music is so clear and beautiful anyway it is quite hard to hear a step change but the delivery is effortless and soft and perfect.

Set Up 2

Naim set-Up, nice and tidy!  The top one is lights and a router switching box!

Then I have moved the EOS Power Cable and the EOS Modular 4.0 Six-Way into my Naim NAC-N 272 and the Naim Uniti Serve using the filtered blocks and the Naim NAP 250 power amplifier has been plugged into the unfiltered supply box.  I have also plugged the HR low noise power supply upgrade for the Michell GyroDec into the filtered block.   I am using KEF R700 speakers here with Atlas Mavros cables.  The difference is clearer here, possibly because my Naim set-up was a bit of a tangle  before and I have really tidied everything up nicely.  Increased roundness and wider presentation are very clearly evident here, and there is a further enhancement to my low end, it is really smooth.    This all lends weight to the idea of buying a Naim XPS to deliver increased performance to my system, something I cannot afford to do but I now know there is real gain to be had.  Turning to the GyroDec, again, with the input into the NAC the vinyl experience is enhanced with the Phono stage input.  Very impressive indeed.

Why is the performance difference so marked with my Naim system?  Smaller room, better system, better speakers (the KEFs are a joy at the moment) or is it because there was a total jumble which I have now rationalised?  I’m not sure, but the difference with this high quality Hi-Fi set-up (discuss the relative merits of Naim below!) is remarkable and if I had the spare cash available for a power supply upgrade this is where I would invest my cash.

Overall

With my Naim NAC-N 272 and NAP 250 the EOS Modular 4.0 Six-Way delivers real audio improvement for my system and I would not hesitate to recommend the upgrade to those who have the means to invest in their HiFi.  Remarkable.

Atlas Cable’s 6-way EOS Modular 4.0 is available from now with a UK SRP starting from £625.00 inc VAT.  The three filtered and three unfiltered version is SRP £725.   You will probably need an EOS power cable too as part of your upgrade.
