QNET NETWORK SWITCH

The QNET is a layer-2, five-port Ethernet switch that has been specifically designed with audio performance in mind.

Compared to other audiophile network switches currently found on the market, which are typically standard switches with a simple upgrade to either the power supply or oscillators, the QNET is completely redesigned from the ground up. Every aspect of this product, from part to placement, was made to perfect the transmission and receival of high-speed audio signals, while achieving extremely low noise operation.

Internally, the QNET uses a high speed, multi-layered, impedance-controlled layout, which optimizes signal routes, minimizing reflections, interference, and crosstalk. It also boasts an extremely low-noise, stable oscillator for the main clock of the device, which allows for minimal jitter and phase noise. It is equipped with six dedicated power supplies, which provide unencumbered current to all parts of the switch, while minimizing noise cross-contamination and ensuring clean, interference-free operation.

Externally, the QNET is manufactured using an extremely durable aluminum housing. This housing not only acts as a heat sink and shield for the device, but also provides physical separation for the five, independent ports, each accommodating an 8P8C (RJ45) connector. The physical separation of each of these ports is a critical and unique design element, ensuring minimal crosstalk and interference within the device.

Each port on the QNET is optimized for its application. Three of the five ports are auto-negotiated 1000BASE-T (1 Gbps) capable, which should be used for the router and other generic network devices. The remaining two ports are fixed to 100BASE-TX (100 Mbps), a speed at which internal noise reduction is possible, making these ports best used for primary audio servers/players or external media sources.

The QNET is provided with its own DC power supply. However, to achieve the best results, the QNET should be powered by Nordost’s QSOURCE Linear Power Supply and connected with Nordost’s award-winning Ethernet Cables.

Whether you stream music and/or video from a local server, a NAS drive, or from the internet, upgrading your digitally-run system with Nordost’s QNET will make all the difference. This premium network switch will deliver enviable dynamic range, extension, and clarity to your system. As a result, the voices and instruments in your music will stand out against a surprisingly black background, giving you the fluid, life-like performance that you are looking for from your digital experience.

 

QSOURCE LINEAR POWER SUPPLY

The QSOURCE is a fanless Linear Power Supply designed specifically for hi-fi audio applications. By providing a stable, clean output of DC power at select voltages, while maintaining extremely low noise levels, the QSOURCE enhances the audio imagery of a sound system by improving sonic articulation, heightening dynamics, and expanding the sound stage.  

The QSOURCE uses a top-of-the-line transformer with a unique circuit design to convert AC to DC power while an internal QRT module removes electrical anomalies and noise artifacts from the line and smooths out the DC output, so that audio components are running on the highest quality DC power possible. From a sonic perspective, this clean power makes all the difference, providing excellent regulation, very low ripple, and outstanding transient response, allowing your components to achieve their peak performance.  

While the QSOURCE was designed to enhance and power as many as four of Nordost’s new QPOINT Resonance Synchronizers, which manipulate electromechanical resonances in order to enhance the coherency and timing of components, it was conceived with versatility in mind. In addition to the four, 5V outputs designated for QPOINTs, the QSOURCE provides two outlets that can supply 9V, 12V, or 19V and 12V, 19V, or 24V respectively, which can be chosen to match the requirements of your electronics. To complete the transmission chain, Nordost has designed purpose-built QSOURCE DC Cables to fit the QPOINT and any other DC-run components in your system.

Whether using it in conjunction with the QPOINT, or as a standalone power supply for DC-dependent audio components, Nordost’s QSOURCE Linear Power Supply will bring new dimension to your sound system, allowing you to enjoy richer and more nuanced musical performances.
