The following is a press release issued by Nordost.
August 2015 - Nordost is proud to introduce the newest addition to the QRT range of power products: the QLINE Ground Wire. Nordost’s QLINE is the most effective method to achieve a solid secondary ground for your hifi audio system. This unique and effective ground wire will not only increase the size and depth of your soundstage, but will reduce the sonic pollution being fed to your audio system, and eliminate the noise generated by the overlapping of multiple circuits or ground loops that are created within electrical circuits.
The QLINE is constructed with a 231 strand, 10 AWG, plated conductor and uses Nordost’s patented Micro Mono-Filament technology, combined with extruded FEP insulation. The QRT Ground Wire serves as the missing link needed to complete the circuit — whether grounding from device to device or connecting the QBASE ground post to a designated, external ground rod or grounding box through its unique, low resistance path.
As is true with all of Nordost’s QRT power products, the QLINE is designed to alleviate the impact of poor quality AC power on your sensitive electronics. By limiting RFI and timing errors associated with the AC line, it brings AC power closer to the desired “distortion-less condition”. Nordost’s QLINE is best used in conjunction with the rest of the QRT range, and will result in a more discernable soundstage, greater dynamic range and a lower noise floor for your system.
Nordost’s QRT Ground Wire is available in multiple lengths with air-tight, waterproof terminations in order to accommodate your specific needs. Installing a designated ground for your hifi system is the most efficient and direct approach to eliminate ground loops and AC hum. However, it is important to consult a local electrician to ensure that the improvements you make to your sound system remain to code.
