Synergistic Research Quark Music Streaming Server

BRAND NEW - JUST ARRIVED - SHIPPING NOW

Quark is the first streaming server engineered from the ground up to eliminate the one problem every other streamer ignores: the high-frequency electromagnetic contamination generated by its own computing architecture.

It inherits the full Synergistic Research field technology stack developed for the flagship Voodoo — electromagnetic cells, ELF/ULF biasing, UEF metamaterials, and carbon fiber architecture — refined across fifteen years of power conditioning, grounding, and digital infrastructure engineering, and transferred into a compact, low-power platform that delivers performance $30,000 competitors cannot match. Not because it’s a better computer. Because it solves a problem they don’t know exists.

Quark ships with a Foundation XL 12 AWG power cable and SR Master Fuse.

Quark features an advanced ELF/ULF biasing system — evolved from the implementation in the flagship Voodoo — that generates a coherent low-frequency electromagnetic field inside the chassis.

The principle is straight1forward. Your home is saturated with MHz-GHz noise from Wi-Fi routers, LED lighting, switch-mode power supplies, smartphones, and dozens of broadband emitters that didn’t exist twenty years ago. That noise rides on every conductor in your system. The audio signal’s phase relationships and harmonic structure propagate through that contaminated field — and arrive at your speakers with the spatial and timbral information compressed, smeared, and degraded.

ELF/ULF biasing doesn’t remove the MHz-GHz contamination. It establishes a coherent field structure that the audio signal couples to preferentially — the way a ship rides the ocean swell, not the surface chop. The contamination is still present. The signal’s relationship to its field environment changes — from riding the chop to riding the swell.

Three selectable ULF frequencies let you voice 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. Systems that benefit from additional warmth and density respond here.

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

These settings don’t color the music. They don’t alter the data stream. They reshape the ambient electromagnetic field environment surrounding the circuit. The difference is immediate.

Electromagnetic Conditioning

The Technology No Other Streamer Contains. Inside Quark’s chassis, the same patented electromagnetic cell technology deployed across the PowerCell line conditioners, Active Ground Blocks, and the flagship Voodoo operates directly on the internal DC power supply and computer circuitry.

Electromagnetic cells don’t filter noise from the signal. They reshape the electromagnetic field environment the signal propagates through — projecting a coherent field that displaces the incoherent MHz-GHz contamination generated by the computing architecture. The distinction matters. Filtering removes noise after the damage is done. Field correction prevents the damage from occurring. And critically — field correction inside the chassis means the contamination is neutralized before it ever reaches the cables connecting Quark to the rest of your system.

This is the technology that separates Quark from every streaming server at any price point. Not better filtering. Not better isolation. A fundamentally different approach — managing the field environment at the point of origin so the signal exits the machine clean, and the noise that would otherwise migrate to every cable in your system stays contained and neutralized inside the chassis.

Fifteen years of development across power conditioning, grounding, and digital infrastructure produced this technology. Quark inherits all of it.

Software Platform

Built for Roon. Designed for Flexibility. Quark runs Roon software, delivering a metadata-driven listening experience with intuitive library management, artist biographies, lyrics, and seamless integration with Qobuz, Tidal, and local file libraries. A Roon account is required.

For the highest possible digital audio quality, pair a Quark with a Voodoo or a second Quark — dedicating one unit as the Roon Core Server and the other as the Roon endpoint. Separating core processing from audio output eliminates the sonic penalties of running both functions on a single device. Each unit focuses exclusively on its task. This dual-server architecture is the same approach used in the flagship Voodoo configuration. Quark makes it accessible at a fraction of the investment.

Mechanical Architecture

Compact by Design. Silent by Engineering. Quark takes form in a compact chassis machined from the same low-resonance materials found across Synergistic Research’s active component line. CNC-machined aircraft aluminum and carbon fiber eliminate vibrational feedback between chassis and circuit, while the entire enclosure acts as a passive heat sink. No fans. No moving parts. No acoustic interference with your listening environment.

The compact form factor isn’t aesthetic. It’s a direct consequence of the low-power architecture. A processor that draws less power generates less heat. Less heat means a smaller chassis maintains the same thermal headroom as the full-size Voodoo. Every dimension serves the engineering.

System Configuration

Stronger Together. 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 and 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 — the Ethernet Switch UEF Mk II, the Network Router UEF, and the full line of digital cables. Each additional component in the chain applies the same field technology and Six Pillars framework, compounding the performance gains across the entire signal path.

Frequently asked questions.

Q. How does the Quark compare to the Voodoo?

A. When outfitted with identical cables, the Quark and Voodoo perform remarkably close. The Quark’s low-power architecture and improved ULF implementation close the gap between the two, making the performance difference far smaller than the price difference suggests.

Q. Can I pair a Quark with a Voodoo?

A. Yes. For optimal performance, use the Voodoo as your Roon Core Server and the Quark as your Roon endpoint, or pair two Quarks with one serving as Core and the other as endpoint.

Q. What digital outputs are available?

A. Two USB input/outputs. One connects to your DAC, the other can be used for external storage.

Q. Is Roon the only interface?

A. Yes. The Quark comes ready to run Roon. A Roon account is required.
