Description

The Nordost QBASE QB8 Mark III – AC Distribution Unit is a premium power distribution unit designed to provide high-end audio and video systems with a clean, stable, and interference-free AC power supply. As part of Nordost’s renowned QRT line, the QB8 Mark III is engineered to optimize the power flow to your equipment, ensuring that each component in your system performs at its highest level. This unit stands out for its advanced grounding technology, low-impedance design, and ability to deliver exceptional improvements in sound quality, clarity, and detail.

Overview

The QB8 Mark III is the flagship model in Nordost’s QBASE series and offers eight high-quality outlets, making it ideal for larger audio and home theater setups. It is designed to serve as a central power distribution hub that enhances the overall performance of connected components by providing a stable, low-noise power supply. The QB8 Mark III employs Nordost’s star-earth grounding system and direct connection design, which ensures that every device plugged into the unit benefits from a consistent and pure power flow, free from the noise and distortion commonly introduced by standard power strips.

Key Features

  • Star-Earth Grounding Topology: The QB8 Mark III uses Nordost’s unique star-earth grounding system, which ensures that each of the eight outlets has a dedicated ground path. This significantly reduces ground loops, hum, and noise, resulting in a cleaner and more stable power supply for your audio and video equipment.
  • Optimized Current Flow: The unit is designed to provide optimal current flow across all connected components, preventing one device from affecting the power supply to others. This ensures consistent and reliable performance throughout your entire system.
  • Direct Connection Design: Nordost’s direct connection design minimizes the internal wiring and connections within the QB8 Mark III, reducing impedance and preserving the integrity of the AC power signal. This ensures that power is delivered efficiently and without degradation.
  • Passive Filtering: The QB8 Mark III incorporates passive filtering to eliminate high-frequency noise and electromagnetic interference (EMI) from the power line. This ensures that your equipment receives a clean, interference-free power supply, which is essential for achieving the best possible audio and video quality.
  • Heavy-Duty Construction: The unit is built with a robust, anti-resonant chassis that minimizes vibrations and mechanical interference, further contributing to the delivery of clean power to your components.

The QBASE Mark III is an elegant yet simple concept that provides the solid foundation that audio components require in order to create and expand upon any high-performing two-channel system. Nordost’s AC Distribution Unit addresses the noise-inducing, conflicting flows of signal and ground paths within a hifi system by using a unique method called “star-earth topology”.

Star-earth topology connects all outlets from one central point (or outlet) to the input. In the QBASE, we do this while additionally lifting the impedance level on every outlet, except for the one deemed “Primary Earth”. Elevating the ground in this passive manner achieves three indispensable effects: it creates an uninterrupted, straight-line AC distribution path from the wall to each individual component, isolates each component by deterring the ground flow between them, and eliminates conflicting flow between signal and ground paths, all without any form of in-line filtering or active circuitry.

QBASE Mark III units are comprised of a mechanically tuned, extruded aluminum body, outfitted with highly durable connectors which have been specifically engineered to maintain excellent connectivity after extended use. The Mark III model features a dual-level PC-board configuration which separates all ground connections from the line and neutral traces, consequently minimizing any interference or crosstalk between live/neutral and ground currents. Additionally, the construction and trace geometry of each PC-board has been vastly optimized to include enhanced trace sizes, further maximizing current flow and crosstalk, and each QBASE Mark III is internally wired with Nordost Mono-Filament wire. Lastly, a resistance “sink” adds protection and more effectively damps eddy currents.

The QBASE Mark III impacts every component connected to it, improving each one in unique ways. The effect it has on a system is all encompassing— enhancing the 3D imaging on the soundstage, pulling out tonal richness and sustained decay time in the music, and imparting a clear increase of power while maintaining a neutral and effortless delivery of the performance.

NORDOST QRT SYSTEM REVIEW

“Reviews sometimes assume a life of their own. This review or at least the idea for this review began when a friend (Sherri) brought a number of Nordost QKOIL models (QV2/QK1) to my home one afternoon so that I could hear them in my system. I had previously visited her home for a demonstration of the QK1 and QV2 and really liked what they did in her system, but was not sure how they might affect my own system. The effects of each. . .”

QRT QBASE QB8 AND NORDOST SORT KONES

“For years it was cables, but these days there is little that rattles the cage of the committed audio puritan like mains conditioners and equipment support cones. Reviews of either is almost bound to elicit a rise in blood pressure and a trip to the keyboard to fire off an indignant mail to some audio forum or other. As for tiny, resonating metal bowls that sit on the wall? Don’t even . . .”
