The QKOIL QK1 AC Enhancer uses a load resonating coil (LRC) to generate a passive electronic field that has a beneficial sonic effect on the AC current.

Like the QV2, The QKOIL provides a vital solution to the issues of AC quality and audio/video performance, but unlike the QVIBE, the new QK1 achieves this by using an LRC furnished with Nordost’s patented Micro Mono-Filament technology. Using our MMF technology in a loading application prevents time delay and distortion of the transmitted signal, making the AC current that much closer to the desired “distortionless condition”. The Sensory results: an improvement in the overtones and pacing of the music as well as a greater sharpness, depth, and focus of visual qualities.

The QKOIL is the entry-level product in the QRT range, a family of modular, non-intrusive innovations that deliver measurable sonic enhancements and provide power in the purest way. Like other QRT products, the benefits are cumulative and QK1s is even more impressive when applied collectively. It can be used as a “stand-alone” product or to complement a full QRT system with QBASE-Mark II, QX4, QX2, and especially QV2 units.

The QK1 is housed in a mechanically tuned carbon-fiber body and equipped with either a US (NEMA), EU (Schuko), or AUS connector. It is compatible with voltages from 110V to 240V and can be used with a UK adaptor if required.  Plug the QKOIL into any spare socket on your system’s AC Line and experience first-hand the surprising yet indisputable effect it will have on you’re A/V components.
