Entreq Hero Ground Box

The Olympus Hero is a new ground box from Entreq, launched in September 2021.

The Hero is effectively Entreq’s flagship ground box and is based around 5 of the Olympus Infinity Tungsten Boxes and a Cleanus (mains cleaner) in one large, newly designed and constructed box. It is built using the same 3 constrained layer method as utilised in the Athena equipment stand.

Weighing in at 60kg and supplied with castors this is one seriously large and powerful ground box!

There are 10 posts on the back, with 5 separate zones of grounding. The addition of the Cleanus is a nice touch as well, simply connect a power cable to the back of the Hero and to a spare wall socket. The Cleanus is designed to remove high frequency noise from the mains and dump into a section of the box.

You could use 2 of the zones on the Hero to ground the negative outputs on your amplifier, leaving 3 separate zones to connect to other part of your system.

If you need greater capacity you can use the supplied bridging ‘T links’ to double up a couple of zones together making it even more effective! There is no right or wrong way to configure a Hero, it all depends on your system. But however it is used it delivers a dramatic uplift in performance – low noise to the extreme, it adds nothing to the presentation of the system, but it allows you to experience your system at its very best.

A single Olympus Infinity Tungsten Ground Box is £4000 and a Cleanus is £1300 so to buy all of the bits that comprise a Hero separately would cost over £20,000!

Available for home demonstration and part exchange is welcome as well.
