Power Management 電源處理


Everything starts with the wall socket !

Actually you ARE indeed listening to your wall outlet.

Never mind that it´s through more or less sophisticated devices. Ultimately the final sonic result from any music system depends entirely on how well you have managed to deal with all the sources of interference found in and around the Power, Power supplies & the associated Grounding of each and every product in your system. It is that power that is converted into sound waves and therefore, in our opinion, the power and ground is where you should start when you are trying to build a natural sounding system.

If you don’t get it right from the start you will simply be ameliorating inherent problems with further links  down the audio chain. Think of this approach as akin to using a graphic equalizer in your system, while in theory it initially appears to have addressed one problem, it can often cause more fundamental issue’s of dissatisfaction else where.

As music lovers we have all experienced, in some form or other, the above process & ultimately something is always lost in the musical translation.

“Duo negative affirmant”

Multiplying two negatives gives a positive.  ” I know” could also be expressed, ” I am not without knowledge “. The content is the same but where the first sounds natural and flowing the second communicates negativity and irritate’s.

It´s the same thing with HiFi and sound reproduction. It might very well seem correct, but just as in the sentence above it will sound forced and bureaucratic
and the more you try to compensate these errors the more sterile the sound becomes.
This is why we think it is so important to start with the power and the grounding first then continue by taking care that the environment and the surrounding equipment are as neutral, natural and the least invasive possible.

Our Power distribution systems work in three distinct areas. Distribution, Cleaning and subsequent Grounding.

Most of the other brands who manufacture Distribution or Power cleaning products concentrate their work on cleaning the phase. This is in an attempt to obtain a nearly perfect 50/60hz wave form. This sounds good in theory and looks good on paper but in our extensive examination of this critical area and in our opinion, the result is still synthetic, unnatural and compressed. It therefore doesn’t actually address the complete and fundamental issue which is about making a greater improvement in AUDIO performance and the pleasure of listening to music! A point to consider and think on – what is it that Electronics manufacturers go to such great lengths to build inside every component they make… Yes a stable power supply for the circuit they have just designed!!

In our examination of this problem we believe that the fundamental issue in the Power network, relative to the sound of our Hifi and ultimately our music, is associated with the Zero and the ground.  Many times in the modern home we are overloaded with products that operate noisy switching power supplies or products that dump noise or field effects directly back in to the mains supply. This of course goes full cycle and so the problem increases! Things like halogen lights,  fluorescent lights, heating pumps, freezers, phone chargers, broadband routers etc are particular culprits. These types of devices typically cause high-frequency interference on the mains but these and other products also litter the ground/earth plane with strong magnetic fields & pulses. This can if in large enough quantities pose a health risks to us humans – but in our terms, as music lovers, this problem negatively effect’s our sensitive audio system as it trys to deal with that delicate signal we call music. In addition we have also examined the effect the audio equipment itself has on introducing noise, ripple effect and further magnetic induced field effects, into the power chain as well as the audio signal itself.

All of our mains oriented products are fundamentally designed to minimize, reduce or negate all of the above issues.
With Powerus we focus on star ground for the outlets, asymmetrical design,cabling with optimized area for handle high frequency, each outlet are feed from one point,and of course no magnetic material.

PowerUs, Cleanus and our range of Ground Box’s are very effective in there own rights but when you hook up a complete system and wire them together with our Eartha cables you really do achieve an outstanding performance, exhibiting a natural, dynamic lively sound with an incredible sense of palpability, freedom and low distortion. This sound can initially be a bit of a culture shock but we are sure with the appropriate guidance from your local agent or dealer you will find a balance and an insight into your music collection.


Powerus Konstantin/ Challenger

PowerUS Challenger PowerUS Challenger-rear

Many times the simplest solutions are the best.The PowerUs range of products have no active filters of any kind! We just use the best material we know and have straight main paths with star ground. You  can get Powerus as Konstantin Powerus Challenger 3 V PowerUs.  Incorporating either a Konstantin or Challenger 3V Powercord,  as well as matching internal wiring to reduce, amongst other things, magnetic field effects, vibrations etc.In US version 6 outlets and in Schuko 4. You also have a outlet for connect to our groundboxes.


Powerus Apollo / Atlantis

For the person with first class musical equipment.  No filters, just the best possible material’s giving a very natural and easy flow in the sound.  Using a hard wired Apollo/Atlantis Power cord, matching internal wiring  and Furutech outlets, you are assured a direct un-interupted signal path for your electronics. Like all PowerUs products a dedicated Entreq Ground point is also available which should be connected to a Silver Tellus or Olympus Tellus.  US version 6 outlets and in Schuko 4 or 6 on request.


Cleanus , Silver Cleanus, Apollo Cleanus, Atlantis Cleanus

CleanUS front CleanUS-rear Silver CleanUS Silver CleanUS-rear

These products are completely passive mains filters. You could more accurately describe them as high frequency separators. High frequency interference and OTHER contaminants are dramatically reduced but without ANY loss of dynamics or dynamic constraints.The result is a quiet and pitch black background. If you connect to Silver Tellus or Olympus Tellus you will get even better impact.What else would you expect from Entreq…
