Questions and Answers: QNET7

We have received an exciting amount of enthusiasm for our new QNET7 Network Switch since its launch this past spring. With this enthusiasm comes a lot of curiosity and questions. So we wanted to share some of the most frequently asked questions regarding our QNET7 here!


Q: What is the QNET7

A: The QNET7 is Nordost’s high-performance Layer-2 Ethernet switch, designed to enhance digital audio quality. Unlike typical modified consumer-grade switches, it minimizes noise and jitter for a cleaner signal path and superior sound quality. It features seven specialized ports with varying speeds and functions, including one offering optical connectivity. The QNET7 Network Switch delivers improved clarity, imaging, and musical fidelity. 


Q: How does the QNET7 differ from the original QNET? 

A: The QNET is already considered a high-performance network switch, and the principal design concepts of both network switches are similar. However, several distinct elements in the QNET7 offer impressive sonic improvements. 

  • It embeds the traces in its multi-layer PCB design, increasing signal speeds, eliminating crosstalk, and protecting the signal from ground noise. 
  • It uses nine separated, completely independent, ultra-low noise linear power supplies within the device. 
  • It features two onboard temperature-compensated, high-precision clocks.
  • Port 7 is a fixed 1000Mbps (1G) SFP port compatible with external 1000Base-T (IEEE 802.3ab) and 1000BASE-LX/SX [802.3z-1998 (CL38)] SFP transceivers/modules, supported by single- and multi-mode fibers.  

Q: How do I know which SFP modules are compatible with the QNET7 to use in “Port 7”? 

A: Refer to Nordost’s continually updated “Compatible SFP Module List” to verify SFP compatibility. 


Q: How can I optimize the performance of my QNET7? 

A: To get the best performance from your QNET7, Nordost recommends the following: 

  • Upgrade the switch-mode power supply provided with the QNET7 to the QSOURCE Linear Power Supply
  • Integrate the QRT Stand Mount along with Nordost Sort Kones, which can be used to support both the QNET7 Network Switch and the QSOURCE Linear Power Supply.
  • Use Nordost Ethernet Cables, available in a range of specifications and price points, to upgrade your digital system. 

Q: Can I use the QSOURCE Cable I use for my QPOINT or “original” QNET to power my QNET7 with my QSOURCE? 

A: No. For the protection of your products, each cable connector is uniquely keyed.  You will need to purchase a dedicated QNET7 QSOURCE Cable to power your QNET7 with the QSOURCE Linear Power Supply.
