If you have ever read the literature about Nordost’s QRT Audio Enhancers, you are familiar with their cohesive and cumulative nature. What does that mean? Two things: QRT products all work together to accomplish their desired effect, and the more QRT products used, the better your results will be.

In this blog, we will take a moment to look at how products that make up the QRT family work together, which of Nordost’s Sort System Resonance Control products can enhance your investment in QRT, and some examples of fully optimized hifi systems, using Nordost’s QRT line.

QBASE Mark III

 The QASE Mark III is a passive AC distribution unit that addresses the noise caused by conflicting signal and ground paths in a hifi system. It does this by using Star Earth Topology, a design that provides ground separation and allows stray voltages and eddy currents to be referred to one, central, ground point. In the current QRT line, the only difference between the QB4 and the QB8 (or the QB6 in the UK) is the number of outlets available to each model­: 4 or 8 (or 6). So, when choosing a QBASE Mark III, simply discern the number of components you need to plug into your system, and the amperage needed to run your system, both QBASE Mark III options are available with either a C-14 or C-20 IEC (C-14 IEC = 15/10 amp, C-20 IEC = 20/16 amp), and you are good to go. For more information on the QBASE Mark III, click HERE.

Products to complement and optimize the QBASE Mark III:

QRT Plug-Ins – QSINE, QWAVE, QVIBE, and QKOIL devices improve upon poor-quality AC. More information on each, individual QRT Plug-In can be found HERE.

QKORE – Grounds the primary side of the power supply through artificial, parallel grounding.

QKORE Wire/Premium QKORE Wire – Offer a connection from the binding post on the QBASE to the QKORE Ground Unit.

QLINE – In appropriate situations, this offers a connection from the binding post on the QBASE to an external ground rod or grounding box.

QRT Stand Mount – Adds stability and the ability to introduce resonance control.

Sort Kones – 4 Sort Kones of your choice to drain damaging vibrations from the chassis of the QBASE.

In a hifi system, every link in the chain makes a difference. In the last 20 years, digital sources have all but taken over the audio world. During this digital revolution, the network infrastructure that supports components like DACs, streamers, NAS drives, etc. has become exceedingly important. A huge part of this foundation is an audio-optimized network switch – a device that may seem inconsequential at first, put actually plays a pivotal role in enhancing digital playback…

Data Transmission Stability

Audio network switches must ensure the stable and reliable transmission of data within a hifi audio system. Uninterrupted data flow is essential for maintaining signal integrity, preventing jitter, and minimizing delays. Nordost’s QNET Network Switch is designed with a high speed, multi-layered, impedance-controlled layout, which optimizes signal routes, provides a stable environment for data transfer, and minimizes reflections, interference and crosstalk. 

Noise Reduction

Audio systems are sensitive to electrical noise, so standard switches, with their inferior craftsmanship, often introduce unwanted interference. With Nordost, you don’t have to worry. Every aspect of the QNET, from part to placement, was made to perfect the transmission and receival of high-speed audio signals, while achieving extremely low noise operation. In addition to the many design features that contribute to noise reduction in the QNET, Nordost’s network switch takes it to the next level, providing five, physically separated, independently powered ports, each accommodating an 8P8C (RJ45) connector. The physical separation preserves the purity of the audio signal and enhances the listening experience. 

Precision Timing 

Timing accuracy is critical in audio reproduction. Network switches help synchronize data packets, reducing timing errors, and ensuring that audio signals are transmitted with precision. Nordost’s QNET utilizes an extremely low-noise, stable oscillator for the main clock which is mounted to the motherboard (unlike most switches, which opt for a sister board mount) to prioritize timing considerations which, in turn, contribute to improved audio clarity. 

Enhanced Streaming Performance

As hifi systems increasingly rely on streaming services for audio content, the performance of the network switch is becoming even more crucial. A high-quality audio switch, like the QNET, helps to optimize streaming performance, reducing buffering times and enhancing streaming quality. 

In the pursuit of the perfect performance, network switches play a crucial role in ensuring the stability, purity, and precision of audio data transmission.

Nordost’s QRT family consists of several impressive audio enhancers. Each of these offerings works as an individually contained solution, with unique objectives for alleviating the poor power quality that impacts audio systems. Since the QRT portfolio is growing, we wanted to briefly explain each QRT solution on the market, and the distinctive benefits that they bring to a system. 

QBASE Mark III

The QBASE is a passive AC distribution unit that addresses the noise caused by conflicting signal and ground paths in a hifi system. It does this by using Star Earth Topology, a design that provides ground separation and allows stray voltages and eddy currents to be referred to one, central, ground point, by lifting the resistance of all outlets on the device except for that of the Primary Earth (which would serve the pre-amp or integrated amp of the system). The QBASE is available with either 8 or 4 outlets (or 6 outlets for the UK model) and uses either an IEC C-14 or C-20 input. 

QRT Plug-Ins

The QSINE, QWAVE, QVIBE, and QKOIL are a range of complimentary, modular AC products that improve upon the AC quality that feeds your home sound system. Whether it’s by generating a field, reshaping a sine wave, or introducing harmonics onto the AC line, each of these unique solutions work to reduce EMI, lower the noise floor, and increase clarity and imagery of the musical reproduction. 

QPOINT

The QPOINT is a resonance synchronizer that manipulates the electromechanical resonances inside the components within its immediate proximity so that they resonate in unison with each other. Synching these resonances eliminates internal electrical noise and enhances the coherency and timing of the components themselves. The QPOINT allows users to switch between two distinct modes, each with their own unique characteristics, to better tailor results for each individual system. 

QNET

The QNET is a layer-2, five-port Ethernet switch that has been designed and constructed from the ground up to maximize audio performance. Every aspect of the QNET, including its multi-layered layout, its six dedicated power supplies, the incredibly stable oscillator for its clock, and the five, independent 8P8C ports, were chosen in order to minimize noise, crosstalk, and interference. 

QSOURCE

The QSOURCE is a linear power supply that provides a stable, clean output of DC Power at select voltages. Its unique design removes electrical anomalies and noise artifacts from the line and smooths out DC output. Meanwhile, a fanless construction maintains extremely low noise levels, which allows heightened articulation and dynamics to shine through digitally-run systems. The QSOURCE is the perfect upgrade to Nordost’s QNET network switch and as many as four QPOINTs, while simultaneously powering two additional digital components (specced to run at 9V, 12V, 19V, or 24V respectively). 

QKORE

QKOREs are parallel grounding devices which provide an artificial, “clean” earth for hifi systems by using both an electrical and mechanical approach. Using Norodst’s Mono-Filament technology, Low-Voltage Attractor Plates, and a passive electronic circuit, QKOREs draw stray high frequency noise and voltage-generated magnetic fields to a manufactured earth point, leaving a clean reference behind. 

While it’s apparent how individualized each of these audio solutions are, it’s important to highlight that the benefits gained from using them together, as a family, can be staggering. Nordost’s QRT family is a holistic approach to achieving great sound. When used in concert, each and every QRT addition to an already well-composed system brings yet another layer of improvement to the musical performance. 

The QRT family truly is a FAMILY of products, and we really encourage you to think of it in that way.
