FAQs
Is OCC copper better than standard copper?
Yes — OCC (Ohno Continuous Cast) copper has far fewer grain boundaries, resulting in cleaner signal transfer, lower distortion, and improved tonal coherence.
Will these cables work with my active monitors?
Yes — they are fully balanced XLR interconnects, suitable for studio monitors, preamps, DACs, and any balanced XLR input/output devices.
Are they flexible enough for tight rack spaces?
Yes — the silicone jacket offers excellent flexibility without compromising shielding or durability.
