K2 & Everest

K2 & EverestK2 & Everest

                        K2 & Everest
Go to the highest level, while still keeping your feet on the ground, with K2 and Everest.

K2 and Everest are a result of my fascination for the Swedish company Hasselblad. They have always put customers first! They have famously always worked hard, wherever and whenever possible, to ensure that any new lens or camera body released in to the market should be backward compatible with the customers existing system. You should not be forced to buy everything new just because you want to be at the forefront of performance.
This position & thinking ensures the status, true value, is synonymous with the name Hasselblad. When Collins dropped his Hasselblad during that famous spacewalk, it gave Sweden their first iconic Satellite. Later it took them all the way to the Moon.

When we at Entreq found a massive new breakthrough for our metal/mineral mix, used within the Ground boxes, we were suddenly faced with a delicate problem. The convenient solution for us would be to release a totally new line of Ground boxes with far better performance than our existing ones.
It would of course be easy for us but not particularly fair to our existing customers who have already invested money in our products. So just like Hasselblad we accepted the challenge to find a solution where all the benefits from our new discoveries could be incorporated & applied to all existing Ground boxes and work, without limits, with our wide range of Eartha cables.
The demand was it should work from our entry level Minimus/Tellus all the way to the Olympus Tellus. Working as effectively with the entry level Eartha Cupper cables as with Eartha Atlantis. It should also be easy to handle and easy to attach. This has truly been a challenge for us!

Finally… the result is K2 and Everest. We have always used wooden caps on our binding posts, wood is totally neutral and adds no new capacity and in that sense it is perfect. The opposite in fact to using plastic’s and most metals, indeed we have used this fact to add our all-new features. You simply replace the wood caps on your existing ground box with either the K2 or Everest product.  
The following are examples of the effective performance enhancements available to both old and new customers:
MinimUs: Single Ground post only - The replacement of a K2 or Everest to a Minimus will then allow it to, at least, out perform a standard Silver Minimus!
Tellus: Three Ground posts -  As above the replacement of the K2 or Everest on a Tellus will offer a performance level higher than a Silver Tellus.
Silver Tellus: Again the K2 or Everest applied to a Silver Tellus will start to approach the performance of the mighty OlympUs!
Everest then applied to OlympUs Tellus and ……well you get the picture!

When  you attache one Everest or K2 on a box with multiple outlets, the performance will be changed for all outlets ( the whole Groundbox)

On ground boxes with multiple outlets you can of course change over each Ground post one at a time as and when funds allow OR of course all at once!

You simply match the K2 or Everest to ens
ure optimal performance. 
Do we have to say that we are proud to present both K2 & Everest?


Garbo 4

Garbo 4Garbo 4

                        Garbo 4

Directly inspired by our work on Athena!

The knowledge we gathered from the development of the Athena project inspired us to develop Garbo. In the summer of 2015 we decided to make a foot that was small , low and easy to instal and could be put places where the space above the equipment was limited. We called it Garbo II.  We have learned a lot during this year with Garbo II and now we are proud to present Garbo 4.
Garbo 4 has a new improved solid construction with even better performance. With 4 metal piers standing on a wood plate,utilizing vibration absorbing materials, it gives the equipment it supports the right  conditions to perform even better. In our testing we wanted to ensure that the Garbo 4 worked well with a wide range of existing rack construction, metal, glass, wood we considered many aspects in the final assembley to ensure consistency. We are very confident that you will find that these little wonders will surprise and delight you.

The price as well as the performance will be a positive surprise for you.

Stereo Times Most Wanted Components 2015 Award!

Ground BoxesGround Boxes

Our ground boxes received  "Most Wanted Components 2015 Award" and "Editors Choice" byStereo Times.

"The Entreq Grounding Silver Tellus was one of my nominees for Most Wanted 2014, I had no idea the potential of the Entreq until I invested in an entire grounding system. I had no idea what the Entreq Grounding system was capable of until I owned the entire system. That includes the Silver Minimus $729 Silver Tellus $2,699, Olympus Minimus $2,599, Olympus Tellus $8,999, Poseidon $4,999 now add in a pair of Silver Cleanus $3140, to pair with an Entreq Challenger 3V Powerus $5,500 and Apollo Powerus $9,700 all paired with Entreq grounding cables (various prices) makes my system sound as though it’s running without any electricity at all. The Entreq removes just about all the electronic properties from my system and makes it perform like it’s powered by batteries. Very lifelike and realistic. The entire system is expensive, however, taking it one step at a time will be worth the price of it all. (Clement Perry, Moreno Mitchell-Stereo Times)"

Third launch of three



OptimUs is a unique cable optimizer, designed and built in house at Entreq. Originally designed to help burn-in & optimise our own wide range of cables, it is therefore fitted with almost every signal connector ( except mains cables), even our Ertha / Ground cables are catered for! Its effectiveness is assured for the Entreq range of cable as well as any other brand of cables that require, from brand new, a relatively quick burn process that brings the cables up to optimal performance in the shortest time possible. Used in position 2 then 3 the OptimUs also offers a recondition/refresh service that is very effective, even when used with established and well run in cables.

Optimus offers three different options/positions for best performance.

1. Square wave -  Sending a square wave with a 9-11 Volt Amplitude through the cable. For analogue cables this should be limited to a maximum of 20-30 
    minutes. For Digital and our Eartha cables we recommend 10-12 hours.

2. Noise -  White noise from 1 Hz up to 40 Khz +-3 db .  Above 40 Khz slowly falling but with significant effect up into the 1 Mhz range. We recommend 48-72
    hours in this mode. For new cables this mode should be used immediately after the Square wave cycle. Step two can also be used frequently for the 
    recondition or refresh of current cables in the system.

3. Sinus wave - Sinus wave with a minimum 9 Volt amplitude, this then gently softens down to silence over a 30 second period.


ES PadES Pad

                          ES Pad

With the design of the ES Pad we have focused on the transfer of very high frequency vibrations & energy. In our design process we found that this area of the frequency spectrum had a far greater influence on actual sound quality than we would have ever thought possible.
The ES Pad is barely 35mm high and incorporates a threaded multi faceted hard acrylic base, with a mineral filled soft Pad making direct contact with the equipment itself. 
This Isolates the equipment from the foundation of what ever it is sited upon while the direct contact of the Pad to the equipment, drains away high frequency energy / vibrations through the mineral mixture itself, converting this energy into a harmless low level heat.

Second launch of three

                         Poseidon has landed!  Grounding, like never before.

The Poseidon can be best described as three totally independent Olympus Minimus in one neat enclosure. With its three pure solid Silver binding posts the Poseidon offers a tremendous level of performance & an almost limitless set of options. One option in particular is the ability to now Ground each channel of your amplifier, via the negative speaker terminals,  while simultaneously & independently being able to Ground your Pre-amp or Dac at the same time. This option alone offers an unrivalled level of performance yet to be attained in any other single Entreq Ground box. This is just one option, please let your imagination and your dealer take you further. 

The Olympus groundboxes are fundamentally different from both the Tellus & Silver Tellus.  The idea for the Olympus was sparked when we designed the “ supercharging “ qualities of the Atlantis MinimUs & Tellus . There were so many unique and interesting details on this development that when we decided to make Olympus we had to free ourselves to implement all that we had learned with no fixed parameters. It was exciting, almost like starting a fresh.

First launch of three

With Serie II we take a significant leap in performance.
We have minimized the quantity of metal and with the new construction we also have secured that the connectors always fit well.
One of the big problem in High End are the lack of standard and the big tolerans for connectors. For example a RCA socket vary betwen 7,85-8,15 mm in dia.
This have caused us a lot of problems before since we always use pure metals and not accept alloy.
With the new Serie II we had take a big leap in soundperformance but perhaps most important also in the way handle the connectors.
