Kemp Elektroniks
was founded 1999 and is located in Amsterdam, the capital city of Holland. The folks at Kemp Elektroniks are audiophiles with heart and soul. The reason why Kemp Elektroniks aim their center of attention at the mains is because this is often a very weak link in any A/V chain.

The design of Kemp Elektroniks' products begins at the measuring workbench, followed by tuning by ear through listening to every modification and component that is added or adjusted. Kemp Elektroniks always takes the time a component needs to be worked in, into account. Several people will attend a listening session and the testing also takes place at several locations. The testing is performed with simple and more sophisticated audio/video sets, and after each modification Kemp Elektroniks goes back to the previous ones taken by removing them step-by-step, and checking to see if they are still an improvement.

One of Kemp Elektroniks products is the revolutionary SR Plug:

THE SCHUMANN RESONANCE PLUG!

  • Shunt device, no dynamic restriction possible
  • Generates a new Schumann resonance
  • Adjustable intensity
  • At maximum level, Schumann overtones are also generated
  • 8 ft. (2,5 m) wire antenna, for optimum results
  • Can be combined with all other mains-related products
  • Multiple SR PLUGS intensify the effect
  • Simple "plug and play" installation
  • 120V 50-60Hz

    What is the Schumann Resonance?
    In 1952, the German physicist Wilfried Otto Schumann discovered that the cavity between the earth and ionosphere acts as an electromagnetic resonant cavity. Energized by electrical discharges (lightning), very low frequency resonances are created around the earth. The lowest frequency (the fundamental) has a frequency of only 7.83 Hz which corresponds with a wavelength of 38,000 km/24,000 miles (the circumference of the earth is about 40,000 km/25,000 miles).

    The ionosphere protects us against harmful radiation from the sun and from outer space, there are indications that the so-called Schumann Resonance plays a role in this. On the earth, mankind is creating more and more high frequency radiation. RFI (Radio Frequency Interference) and EMI (Electro Magnetic Interference) will pollute your A/V set and also your listening room and your body.

    What does it do?
    The newly generated 7.83 Hz wave by the SCHUMANN RESONANCE PLUG will counteract the effects of this radiation. With the SR Plug in place you will notice a clearer, more powerful and dynamic sound with a richer timbre, more details and a deeper soundstage.

    Where to install?
    For best results, we advise positioning the wire antenna vertically in the middle between your loudspeakers. Most practical way to do so, is to attach the antenna to the wall behind them. Under most circumstances, the middle position of the level adjuster is the most pleasant one, but feel free to turn it up a little more, in which case you'll hear more detail and precision. You may notice a slight decrease in timbre, but this will mainly depend on the set used, the listening room and your personal taste.

    Customer feedback:

    "...I hooked it up last night. This thing is nothing short of amazing- it's presence worked a great improvement in my system. The reviews of this device were right on the money: it may be the most cost-effective tweak I have ever used."

    "The music presentation is super clear, even more dynamic and soundstage depth and width presentation is so real. This is the most significant tweak in my 20 years into hifi. Simply breathtaking..."

    Reviews:

    Home Studio, May 2008, John van Polen
    "The effects of the SR-plug are totally different from the ones of the QA-plug. The effect is more in the area of clarity, damping, purity, and the total suppression of noise. A cleaner, more analytical sound with more details, without a shrinking of the soundstage. After a few days of settling, the combined effects of both plugs have become even more noticeable. The sound has become more natural, it simply sounds more like real music." read the entire review

    "The sonic benefits of adding the Kemp SR plug(s) into my listening space were immediate and obvious. With the RR-77 still powered up, I could easily hear greater three-dimensionality placing a single Kemp SR plug directly center, between my Sunny loudspeakers. Yes, all the accolades formerly applied to the RR-77s were applicable to the SR plug. A greater sense of air and bloom seemed to surround instruments. The acoustic space of each recording also made itself more apparent making the leap of faith of "being transported to the recording" that much more believable." read the entire review

    "In conclusion, I am in total concurrence with CP's review. I also agree with Mr. Kemps brochure that the SR Plugs "provide a richer more detailed and holographic sonic experience." Switching them out to conduct a quick A/B was very easy by simply unplugging them. Immediately, upon doing this, I noticed a less dimensional stage with images stuck more to the physical plane of my loudspeakers." read the entire review


    The other Kemp Elektroniks products that is just as impressive is the QA Plug:


    THE QUANTUM APPROACH PLUG!

  • Shunt device, no dynamic losses possible
  • Uses Quantum Resonance Technology (QRT)
  • Two circuits, (LF and HF) using separate power supplies
  • Adjustable intensity
  • Multiple QA PLUGS intensify the effect
  • Simple ‘plug & play’ installation
  • 110-240V 50-60Hz

    The basic principle comes from Quantum Resonance Technology. Inside the QA PLUG are two electronic circuits, a low frequency and a high frequency (QRT) circuit. The principle and the way it works cannot easily be explained in a few words. Put simply, the QA PLUG uses a tiny amount of energy from the mains to manipulate the energy in a room positively. In particular by the influence it has on existing electrical fields.

    Electro sensible people will likely benefit from QRT too. Developed for computer monitors in the 80s by Coherent Technologies, it prevented the huge amounts of EMI/RFI they radiated. A few audio manufacturers later discovered that this technology also works well for audio/video purposes.

    The best location for a QA PLUG is the mains distribution block from your A/V set. The QA PLUG is equipped with intensity control to adjust the effect to your preference. If you find the effect too strong you can also install it in a wall outlet further away from the A/V system. After installation of the QA PLUG it takes 30 to 60 minutes to achieve the best results.

    Review:

    Stereo Times, March 2011, Dave Allison NEW!
    "...there were two consistent benefits: the first is a reduction in treble sibilance. Female vocals and cymbals are the main beneficiaries of this effect. The second improvement is an increase in the specificity and dimensionality of the instruments and (especially) voices ...the Kemp device has the same effects (or to the same degree) as the Nordost products, but the theory of operation seems to be similar, and the price is right! The Kemp QA Plug remains in my system, and is, in my opinion, a worthwhile system tweak." read the entire review

    Customer feedback:

    "Wow. Immediately connected to my Exact Power distributor I can distinguished the dramatic improvement to the sound. Wide spacious soundstage with good timber in the instruments. Best outcome is still at 11 o'clock settings and it really sound much better after 30 minutes of running in...."

    "...the increased detail (from full output) of the QA was not exaggerated, but to my ear a bit too much of a good thing. I then suggested we turn the output down a bit (to approx. 75%). Here the QA was near-perfect....tons of micro-detail, spaciousness, and venue information, but very, very musical..."


    Another amazing Kemp Elektroniks product is the SNS Plug:


    THE SHUNT NOISE SUPPRESSOR PLUG!

    The SNS PLUG is a unique product on the market. In a very simple and affordable way, a cleaner and thus better mains power is provided for your A/V set. All components benefits from this. The result is a clearly improved reproduction in all aspects.

  • Shunt filter, no dynamic restriction possible
  • Super fast reaction speed covering an ultra-wide frequency range, up to almost 1 Gigahertz/cycles
  • Lowers the shunt AC line impedance
  • 7 stages provide the best performance
  • Over voltage and surge protector
  • Potted in resin to prevent microphonic effects
  • Can be combined without any problem with all other audio mains related products
  • Simple ‘plug & play’ installation
  • 110-240V 50-60Hz

    We are surrounded by electrical appliances more and more. Computers, peripheral equipment, wireless telephones, chargers, multiple TV sets, games consoles, microwave ovens, dishwashers etc. are common in most modern houses. All these appliances pollute the mains with noise and distortion. This pollution has a very strong - and highly underestimated - negative effect on the sound and picture quality of any audio/video system. The SNS PLUG is the most simple and effective way to reduce mains pollution. It is one of Kemp Elektroniks most successful products for years with thousands of satisfied customers.


    The SNS PLUG consists of 3 resistors, 7 capacitors, 3 varistors and an inductor. All parts are the best quality available. After testing, the entire circuitry is potted with a permanent resin to create an even quieter sound by preventing mechanical resonances.

    The result of the SNS PLUG is a lower noise floor, higher definition, a wider & deeper soundstage, better resolution of lower frequencies and less treble harshness with more detail. The dynamic performance will be better too. You will hear the improvement immediately. Also, or especially, in combination with other line conditioners and the Kemp SR-Plug and QA-Plug!
