SP3000T Copper

Astell&Kern always strives to create more than just sound, focusing on excellence in sound quality.
The SP3000T COPPER Edition demonstrates this philosophy by delivering exceptional sound characteristics.
Copper, known for its excellent sound transmission and resonance properties, typically enhances the brightness and richness of tones in musical instruments. This quality has been repeatedly validated in Astell&Kern products using copper for its outstanding electrical conductivity and high shielding performance. Copper, because of its material properties, oxidizes and discolors upon contact with air. The SP3000T COPPER Edition utilizes over 99.98% pure copper with a special multilayer coating that enhances durability, ensuring it maintains its beautiful color and luster without requiring special maintenance. Created using proven Astell&Kern technology, the SP3000T COPPER Edition offers more than just music—it provides an emotional experience beyond music.

We invite you to experience the emotions delivered by the pure original sound of the SP3000T COPPER Edition.

True Analog Sound with
Real Vacuum Tube

The original vacuum tube is known for its warm sound, attributed to its distinctive rich harmonics, which have cemented its status as a cherished component of Hi-Fi audio. However, its impracticality in terms of miniaturization, primarily due to power control and footprint issues, presented a formidable obstacle, rendering it unsuitable for
