Nordost QNET Audiophile Network Switch

Purchased brand new from an authorized Nordost dealer- very little use on it, the only reason I'm selling it is because i changed my Audio room network setup and no longer need a switch.

One of the best audiophile switch on the market currently

Improved Dynamics, Ink-Black Backgrounds, and Better Clarity: Nordost's QNET Network Switch Allows Your System To Perform at its Best

A superb Ethernet switch can make a huge difference in your entertainment system — and in your peace of mind. 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 Network Switch will make a significant improvement. This premium network switch will allow your system to deliver a greater dynamic range, better extension, and improved clarity. As a result, the voices and instruments in your music will stand out against an ink-black background, allowing you to enjoy stunningly accurate, lifelike playback.

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 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 the QNET, from each part to its careful placement, was made to perfect the transmission and receival of high-speed audio signals, while achieving extremely low-noise operation.

Internally, the Nordost QNET uses a high-speed, multilayered, 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 that provide unencumbered current to all parts of the switch, while minimizing noise cross-contamination, thus 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 unit, 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 unit.

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.
