What customers say
The Atlas Mavros Grun Ultra cables are celebrated as essential components that profoundly transform audio systems. Reviewers consistently praise the proprietary Grun grounding technology for dramatically lowering the noise floor, resulting in blacker backgrounds and revealing subtle micro-dynamics. Listeners report exceptional clarity, natural timbre, and an expansive, holographic soundstage. The bass is deep and articulate, while the treble remains smooth and detailed without harshness. Although these cables represent a substantial investment in the ultra high end, the consensus is that the resulting transparency and musicality fully justify the premium cost. Many consider this an endgame upgrade for achieving absolute sonic purity in reference systems.
Know before you buy
The GRUN system provides a dedicated grounding path that helps eliminate radio frequency interference and noise. By grounding the cable's screen independently, it creates a quieter background, allowing for better detail retrieval and a more stable soundstage.
Cold-welding creates a gas-tight, high-pressure connection between the conductor and the plug. This method avoids the heat damage that can occur with soldering, ensuring the integrity of the 6N OCC copper and maintaining a consistent signal path.
6N OCC (Ohno Continuous Cast) copper is 99.99997% pure, which significantly reduces the number of crystal boundaries in the metal. This allows the audio signal to travel with less impedance and distortion, resulting in a cleaner, more transparent, and faster sound.
Yes, the Mavros Grun Ultra is available with either banana or spade terminations. You should choose based on the binding posts of your specific amplifier and speakers to ensure the most secure mechanical connection.
The combination of a copper/Mylar electrostatic screen and a copper braid acts as a barrier against external electromagnetic and radio frequency interference. This shielding ensures that the delicate audio signal remains protected from noise generated by other electronic components in your system.
While the Mavros Grun Ultra is designed for high-end performance, its low-resistance construction makes it highly efficient over longer distances. However, as with any high-fidelity cable, keeping the run as short as necessary is always recommended to maintain optimal signal integrity.
