Grimm Audio's SQM takes the Star Quad geometry that has been a studio standard for decades and refines every aspect of it: carbon-doped sheaths kill microphony, a tightly woven braided screen blocks electromagnetic interference, and the four-conductor layout itself suppresses magnetic field pickup. Sold as a stereo pair with Neutrik gold-plated XLR or WBT NextGen RCA connectors, the SQM brings Grimm's measurement-driven engineering to the last link between your components.\u003c\/p\u003e\n\n\u003ch5\u003eKey Features of the Grimm Audio SQM Interconnect Cable\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStar Quad Geometry:\u003c\/strong\u003e Four conductors arranged in a star pattern provide inherent magnetic field rejection, reducing hum and interference pickup far below what standard twisted-pair designs achieve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbon-Doped Sheaths:\u003c\/strong\u003e Individual conductor sheaths and an additional layer beneath the braided screen are loaded with carbon to dampen microphonic noise from cable movement and vibration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed Braided Screen:\u003c\/strong\u003e A tightly woven braid with no visible gaps provides continuous electromagnetic shielding across the full frequency range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeutrik XLR \/ WBT RCA Connectors:\u003c\/strong\u003e Balanced pairs use Neutrik gold-plated XLR connectors.

Any external magnetic field induces equal and opposite voltages in the two legs, canceling the interference. This is not a new idea in professional audio, but Grimm's implementation goes further than most. The carbon-doped inner sheaths address something that standard star quad cables ignore: microphonic noise generated within the cable itself when it flexes or vibrates. By damping conductor-to-sheath friction at the source, the SQM keeps its noise floor below what the connected electronics can even resolve.\u003c\/p\u003e\n\n\u003ch5\u003eShielding Without Compromise\u003c\/h5\u003e\n\u003cp\u003eMost braided shields have small gaps between the woven strands that allow high-frequency interference through. The SQM's braided screen is woven tightly enough that there are no see-through gaps, providing a continuous barrier. For the unbalanced (RCA) version, Grimm takes additional care in the assembly so that the screen functions purely for shielding against hum and RF without interfering with the star quad's magnetic cancellation. This is a subtlety most cable manufacturers overlook when adapting balanced designs for single-ended use.\u003c\/p\u003e\n\n\u003ch5\u003eFrom the Studio to the Listening Room\u003c\/h5\u003e\n\u003cp\u003eGrimm Audio builds products used in mastering studios and broadcast facilities across Europe. The SQM grew out of that professional background, where cables need to be quiet, durable, and thin enough to route through cable trays alongside dozens of other runs. In a home audio system, these same qualities translate directly: low noise floor, no microphonic coloration, and a cable thin enough to route cleanly behind a rack without forcing components apart. Available in lengths from 0.5m to 5m (XLR) and 0.5m to 3m (RCA), with custom assemblies available on request.\u003c\/p\u003e\n\n\u003ch5\u003ePart of the Grimm Audio System\u003c\/h5\u003e\n\u003cp\u003eThe SQM is the ideal analog interconnect for any Grimm system.
