About Pure Copper
Pure copper emphasizes high-purity copper in both chemical and engineering contexts, generally reaching 99.9% purity.
– Chemical symbol: Cu
– Common industrial grades:
– T2 copper (China GB standard)
– C11000 / ETP Copper (U.S. ASTM standard, Electrolytic Tough Pitch Copper)
High-purity copper provides exceptional conductivity, thermal stability, and corrosion resistance, making it ideal for precision audio devices. Unlike traditional aluminum bodies, pure copper offers superior electrical conductivity and natural EMI shielding, ensuring stable power output and reduced background noise for cleaner, purer sound. Its physical density enhances tonal depth and smoothness, producing a warmer, fuller, and more natural sound signature, especially in the midrange and bass — the kind of analog warmth true audiophiles crave.
Why It’s Special
– Pure copper body — lustrous, durable, and beautifully timeless
– Naturally blocks EMI & reduces noise — for pristine, interference-free playback
– Deeper, smoother, more natural tone — a warmer sonic character that feels alive
– Individually numbered (limited to 699 units) — a rare collectible masterpiece
Over time, the copper surface develops a unique patina. With regular care — such as gentle polishing with a soft cloth or using a specialized copper paste — it gradually gains a soft, elegant sheen that reflects your personal touch. Each unit becomes one of a kind — a living, evolving work of audio art.
