NORDOST QRT QKOIL (QK1) – AC ENHANCER
Nordost’s QRT AC Enhancers and AC Line Harmonizers are a range of modular, complimentary AC products which improve upon the poor-quality AC that negatively affects the audio/video performance of two-channel and home entertainment systems.
Description
The Nordost QRT QKORE QKOIL (QK1) – AC Enhancer is a sophisticated power purification device designed to improve the performance of high-end audio and home theater systems by enhancing the quality of the AC power supply. As part of Nordost’s QRT line of power products, the QK1 is engineered to provide a cleaner and more stable AC current, which results in an overall improvement in sound and image quality for your audio and visual equipment.
Overview
The QK1 is an AC line harmonizer that works by introducing a passive electronic coil (inductor) into your AC supply. This coil is specifically designed to generate a low-level field effect, which enhances the AC signal and reduces noise and interference. By doing so, it helps to improve the sonic characteristics of your system, leading to a more detailed, dynamic, and immersive listening experience.
Key Features
- Passive Electronic Coil (Inductor): The core of the QK1 is its passive electronic coil, which is designed to introduce a low-level field into the AC line. This helps to stabilize the AC signal, resulting in cleaner power and less distortion.
- Plug-and-Play Design: The QK1 is incredibly easy to use. Simply plug it into any empty socket on your power distribution block, power strip, or wall outlet. No additional installation or setup is required, making it a convenient addition to any audio or home theater system.
- Harmonic Field Enhancement: By generating a harmonic field, the QK1 helps to smooth out inconsistencies in the AC power supply, reducing the impact of high-frequency noise and electromagnetic interference on your system’s performance.
- Scalable Solution: The QK1 can be used on its own or in combination with other Nordost QRT products (such as the QV2 AC Line Harmonizer or QBASE Power Distribution Unit) to achieve even greater improvements in power quality and system performance.
Benefits of the Nordost QK1 AC Enhancer
- Improved Sound Quality: The QK1 helps to reduce noise and interference in the AC supply, resulting in clearer, more detailed sound with enhanced dynamics and a deeper, more focused soundstage. This translates into a more natural and lifelike listening experience.
- Enhanced Visual Performance: When used with video equipment, the QK1 can improve image quality by reducing visual noise and enhancing contrast, color accuracy, and overall picture clarity.
- Greater System Efficiency: By optimizing the AC power supply, the QK1 helps your audio and video components perform more efficiently, potentially extending their lifespan and ensuring consistent performance.
Ideal Use Cases
- High-End Audio Systems: Audiophiles looking to enhance the performance of their high-fidelity audio systems will appreciate the noise reduction and improved clarity that the QK1 brings to the AC power supply.
- Home Theater Systems: For those with advanced home theater setups, the QK1 can improve both audio and video quality, providing a more immersive viewing experience with improved sound effects, dialogue clarity, and visual details.
- Power Distribution Enhancement: The QK1 is an excellent addition to power distribution setups, whether you’re using a basic power strip or a more advanced power distribution unit. It can be used in multiple outlets to increase the overall effectiveness of your power conditioning.
How to Integrate the QK1 into Your System
The Nordost QK1 is designed for simplicity. To use it:
- Plug the QK1 into any available socket on your power distribution unit, power strip, or wall outlet. It works most effectively when placed in an outlet close to your audio or video equipment.
- For optimal results, combine the QK1 with other Nordost QRT power products like the QV2 or QBASE to create a more comprehensive power purification solution.
Who Should Consider the Nordost QK1?
The QK1 is ideal for audiophiles, home theater enthusiasts, and anyone looking to maximize the performance of their high-end audio and video systems. If you have invested in high-quality equipment, integrating the QK1 into your setup will help you achieve the full potential of your components by providing a cleaner, more stable AC power supply.
Comparison with Other Nordost QRT Products
- QV2 AC Line Harmonizer: While the QV2 actively filters and harmonizes the AC supply, the QK1 works passively by introducing a low-level field effect. Using both devices together can yield even greater improvements in power quality.
- QBASE Power Distribution Unit: The QK1 complements the QBASE by enhancing the quality of the power that reaches your equipment. When used together, they create a synergistic effect that significantly improves system performance.
The Nordost QRT QKOIL (QK1) – AC Enhancer is a highly effective and easy-to-use device that offers significant improvements in the performance of high-end audio and video systems. By introducing a passive electronic coil to your AC power supply, the QK1 reduces noise, interference, and distortion, resulting in a more detailed, dynamic, and immersive experience. Whether used on its own or as part of a complete Nordost QRT power system, the QK1 is a valuable addition that ensures your equipment performs at its best, delivering exceptional sound and visual quality.
Nordost’s AC Enhancers, the QKOIL and the QSINE, are both passive field generators. While the QKOIL generates a field created by its Micro Mono-Filament-made Load Resonating Coil (LRC), the QSINE reshapes the sine wave by introducing specific frequency fields onto the circuit path which, in turn, lowers the effects of EMI noise embedded into the AC power.
Nordost’s AC Line Harmonizers, the QVIBE and the QWAVE, on the other hand, are active devices. They each introduce their own carefully calculated ranges of pulsed frequencies, clocked from the original 50 or 60Hz waveform, directly onto the AC line. This manipulation of the AC signal allows these products to better control the harmonics and overtones attributed to many improvements, not least of which is the enhanced realism of both the musical and visual aspects of performance.
While the effects of Nordost’s QRT plug-ins are clearly apparent when used individually, the benefits of the QVIBE, QKOIL, QSINE, and QWAVE are cumulative and are best enjoyed when integrated into a full suite of QRT products.

A PAIR OF TWEAKS FROM NORDOST QVIBE AND QKOIL
“There’s no doubt the QV2s give you a generous mid-and-upper-bass assist, and the QK1s round and flesh out the treble range. From the hefty, well-defined low-end into the clear mids and the soft-edged, non-abrasive highs, frequency response and tone are beautifully rendered. The palpable illusion of instruments present is . . .”
– Marshall Nack, Positive Feedback
“Reviews sometimes assume a life of their own. This review or at least the idea for this review began when a friend (Sherri) brought a number of Nordost QKOIL models (QV2/QK1) to my home one afternoon so that I could hear them in my system. I had previously visited her home for a demonstration of the QK1 and QV2 and really liked what they did in her system, but was not sure how they might affect my own system. The effects of each. . .”

NORDOST QRT POWER PRODUCTS REVIEW. PART 3 OF 3: QVIBE QV2 AC LINE HARMONIZER & QKOIL QK1 AC ENHANCER
“We’ve talked about the Qv2 and the QK1 separately but bringing them together was another experience unto itself. With all four (two Qv2’s and two QK1’s) plugged into the QBASE, the best of both was achieved. There was greater warmth, yet also greater focus and pace. There was an increased sense of naturalness but . . .”
