Entreq
Poseidon Tri Cell
Ground Box

The Sound of Nature

The Entreq range of ground boxes is designed to remove noise and pollutants present in the signal path. By removing these unwanted pollutants the Poseidon lowers the noise floor and subsequently improves the performance of the connected product. This improves dynamics, detail retrieval whilst remaining natural and organic in presentation.

The mighty Poseidon is effectively 3 independent Olympus Minimus’s in one rather heavy box!

It’s the same width as a Silver Tellus, is a little taller, quite a bit deeper and considerably heavier. It offers an almost limitless number of grounding options and is quickly becoming the reference point within the range of Ground Boxes. The ability of the Poseidon is considerably higher than any other Ground box (apart from the flagship Olympus Tellus), due to the mineral mixture it contains. Compared to the Silver Minimus, Olympus Ten, Tellus 2 and Silver Tellus the Poseidon has so much more capacity and ability, unlocking previously hidden textures in recordings you didn’t know were there with greater air and space around the musicians who are playing.

By having all 3 ground posts independent from each another means you could take an integrated amplifier and ground the negative speaker outputs on the 2 outside posts and ground the input of the amplifier on the centre post. If you have a pre-power combination you could also ground this way. The options are almost limitless and can vary from system to system.

Entreq offers a friendly word of warning about the Poseidon – don’t listen to one unless you are ready to buy one, it’s a bit of a gamechanger once you’ve heard it!

Ultimately a demonstration in your own home with your own system will show you everything you need to know. At less than 5000 Euros, the Poseidon genuinely represents great value for money.

Replace the standard wooden binding post on the back of a Poseidon with either an Everest or K2 binding post and you will dramatically improve its performance, even though they are relatively inexpensive they still make a dramatic improvement to whatever you connect them to!
