Nordost – QRT QSource Power Supply

Provide Stable, Clean Power to Your DC-Based Audio Devices with the Fan-Free Nordost QSource Linear Power Supply: Hear Enhanced Dynamics, Soundstaging, and Imaging

Exclusively engineered for high-end audio applications, the Nordost QSource linear power supply is guaranteed to drastically improve your system’s articulation, dynamics, dimensionality, soundstaging, and imaging. Devised to work in concert with Nordost’s QPoint Resonance Synchronizers, as well as any DC-dependent audio components, QSource provides stable, clean DC power while retaining an extremely low noise level. The fan-less design features a reference-class transformer with unique circuitry to convert AC to DC. An internal QRT module removes electrical anomalies and nasty artifacts from the line and smooths the DC output, ensuring your components run as they should – with remarkable purity. Sonically, QSource accounts for excellent regulation, low ripple, and extraordinary transient response.

In addition to the four 5V outputs designated for QPoints, QSource has two outlets that supply 9V, 12V, or 19V and 12V, 19V, or 24V, respectively, that can be chosen to match the requirements of your electronics. So, whether you’re using a music server, network switch, external DAC, or phono preamplifier with an external switch-mode power supply, QSource will elevate your game and lower your noise. 100% Music Direct Guaranteed.

“There is a sense of drilling deeper into system performance with QPoint, and deeper still with QSource. Equipment that is already singing sings a lot better with QPoint and QSource in place.”
– Alan Sircom, Hi-Fi+, 2019 Accessory of the Year Award

“After listening to them in my own system, [I] can enthusiastically attest that both the QPoint and QSource provide valuable sonic benefits in a high-end system.”
– Jacob Heilbrunn, The Absolute Sound

“For the audio consumer, the laws of price and performance are writ in stone. You get what you pay for. Certainly that applies to the three linear power supplies that I auditioned over the last year or two…. To introduce intangibles like atmosphere and timbral finesse, along with tangibles like deep resolution and transparency out to the corners, you might consider the Nordost QSOURCE. It’s at a different price point, but I don’t think you’ll be able to get the top-tier performance it delivered for less [money elsewhere]. Frankly, the level of refinement the QSOURCE LPS brought exceeded my expectations; my quest for a Hi-End LPS ends here.”
