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.
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
use in portable audio players.
In Astell&Kern's unyielding quest for innovation, we refused to settle for conventional
sound and design, and instead worked to bridge the gap between stationary and portable audio by infusing
the essence of analog sound into our devices.
These efforts eventually culminated in the pairing of the SP3000T with the RAYTHEON JAN6418
Miniature vacuum Tube. The RAYTHEON JAN6418 is a mini vacuum tube popular among audiophiles. Designed to
meet military specifications and traditionally used in military communication equipment, it quickly
garnered recognition for its distinctively warm and soft sound, leading to its integration into regular
audio devices.
Due to inherent differences in noise and amplification among original vacuum tubes,
Astell&Kern adopted a meticulous selection process to adhere to our philosophy of addressing
even the minutest differences in sound quality.
Astell&Kern carefully measures and pairs each JAN6418, a difficult process demanding
both time and precision. This thorough selection method minimizes output deviation between the
left and right channels, resulting in more natural sound reproduction.
Every shielding operation on the vacuum tube is carefully executed by hand to minimize
potential noise interference.
Thanks to our unwavering dedication to sound craftsmanship, we have successfully brought
the distinctive spatial sense and balance found in our existing audio players into the analog
realm of vacuum tube sound.
The integration of vacuum tubes into compact, portable devices presents a formidable technical
hurdle — maintaining low noise levels while delivering unparalleled resolution and robust
output.
With the SP3000T, we've tackled this challenge head-on with a custom-made solution designed
to minimize microphonic noise. Our team devoted extensive time to refining the structural integrity
of the vacuum tubes, ensuring minimal noise even in the event of minor shocks or vibrations.
1. Independent modular, flexible PCB design engineered separately from the main PCB
2. Silicone module case designed to absorb primary shocks from the vacuum tube
3. Silicone tubing perfectly tailored to the vacuum tube leads to reduce shock transmission
along the leads
4. Silicone dampers around the vacuum tube suspend the tube in the air from both ends
* Microphonic Noise might be audible when bumping against the player itself or knocking it against a table.
After testing the operational range of the vacuum tube, we developed an internal plate voltage
control system, which can be adjusted in three stages and directly affects the amplification rate of
the vacuum tube amplifier, resulting in nuanced changes in sound texture.
Experience the subtle shifts in density and spatial presence in your headphones or earphones as
you fine-tune the current of the vacuum tube amplifier.
