Fanless Audio-Grade DC Power Supply | Brisbane HiFi Audio Specialist
The Nordost QSOURCE is a reference-grade, fanless Linear Power Supply (LPS) designed specifically for demanding HiFi and digital-audio applications.
Rather than relying on conventional switch-mode wall adapters, the QSOURCE provides stable, low-noise DC power for compatible audio components and Nordost accessories. Its substantial transformer, internal QRT noise-suppression circuitry, and multiple independently selectable output voltages make it particularly versatile for digital streamers, network switches, DACs, phono stages, and QRT tuning accessories.
At Brisbane HiFi, we recommend the Nordost QSOURCE as a central DC power upgrade for compatible Nordost products including QPOINT, QNET, and other DC-powered audio components across Brisbane, Queensland, and Australia.
Key Features & Audio Engineering Highlights
Internal QRT Noise Suppression Module
Integrated QRT circuitry is designed to reduce unwanted electrical artifacts and smooth the DC supply, helping provide a cleaner power environment for sensitive:
- Digital clocks
- Network circuitry
- DACs
- Analog audio stages
Dedicated QPOINT Power Hub
Four dedicated 5 V DC outputs allow the QSOURCE to power multiple Nordost QPOINT Resonance Synchronizers from a single linear power supply.
Multi-Voltage Output Versatility
Two independently selectable variable outputs accommodate a broad range of DC-powered components.
Variable Output A:
Variable Output B:
This allows the QSOURCE to serve multiple component types within a carefully configured system.
Fanless Silent Operation
The QSOURCE uses its substantial extruded aluminum chassis as a heatsink, eliminating cooling fans and their associated mechanical noise.
High-Speed Transient Delivery
The linear supply is designed for high peak-current delivery, providing stable DC power during demanding transient events and dynamic musical passages.
