Synergistic Research Quark Streaming Server

The Smallest Particle Carries the Greatest Force

The Quark Music Streaming Server takes everything Synergistic Research learned engineering the Voodoo and concentrates it into a compact, low-power architecture that changes what’s possible at this price point. A smaller chassis. Simplified circuitry. A refined power supply. And an improved ULF antenna implementation that pushes the technology further than the original Voodoo design.

The result is a streaming server that, when outfitted with identical cables, performs remarkably close to the full-size Voodoo. Not close for its size. Not close for its price. Close, period.

This isn’t a scaled-down Voodoo. It’s a fundamentally rethought one.

Less Power
Less Noise
More Music

In digital audio, power is the enemy of purity. Every watt a computer draws generates electrical noise that contaminates the signal path. High-performance CPUs, complex motherboards, and power-hungry components all add thermal and electromagnetic interference that no amount of downstream filtering can fully undo. The most advanced audiophile servers in the world have arrived at the same conclusion: the quietest server is the one that draws the least power.

The Quark’s low-power architecture embraces this principle from the ground up. By selecting a simplified motherboard and lower-power processing platform, the Quark dramatically reduces internally generated noise at the source. This isn’t a compromise. It’s a strategic advantage. Fewer active components mean a shorter, cleaner path from storage to output.

A simplified power supply means less conversion noise and fewer regulation stages between the wall and the circuit. The result is a digital transport where the music emerges from a background so black it redefines what you thought your DAC was capable of.

The Quark features an improved ULF antenna and implementation that advances the technology originally developed for the Voodoo. This next-generation ULF circuit addresses ambient RF noise that degrades digital circuits, synchronizing the electromagnetic environment to the Earth’s Schumann Resonance for a dramatic reduction in high-frequency hash and digital compression.

Three selectable ULF frequencies let you voice the Quark to your system, your room, and the music you’re listening to:

Blue (Default): Linear note transitions from low to high frequencies with a relaxed midrange. Large, enveloping soundstage. The natural starting point for most systems and recordings.

Green: Slightly more forward midrange presence with added bass weight. A compelling alternative for systems that benefit from additional warmth and density.

Red: Optimized for recordings mastered with significant phase information and holographic soundstaging. Electronic, ambient, and large-scale orchestral recordings take on surreal three-dimensional depth.

These settings don’t color the music or alter the data stream. They reshape the ambient RF environment surrounding the circuit, and the audible difference is immediate.

The Quark is engineered to perform as a standalone streaming server. It’s also engineered to scale.

Quark + Voodoo: Use the Voodoo as your Roon Core Server and the Quark as your dedicated endpoint. The Voodoo handles library management and processing while the Quark focuses exclusively on audio output, delivering the cleanest possible signal to your DAC.

Quark + Quark: Two Quarks operating as a dedicated core/endpoint pair deliver reference-level separation at a combined investment well below a dual-Voodoo configuration.

Both configurations benefit from the complete Synergistic Research digital ecosystem, including the Ethernet Switch UEF Mk II, Network Router UEF, and our full line of digital cables. Each additional component in the chain applies the same UEF technology and Six Pillars framework, compounding the performance gains across the entire signal path.
