ANALOG WARMTH, DIGITAL PRECISION

Astell&Kern’s ethos of producing immersive sound from high-resolution original music stands as a testament to the spirit of innovation and excellence embodied in the A&ultima series. Their goal was to surpass the impeccable design and high-resolution sound of their previous flagship SP3000 by crafting an audio player that truly captures the emotion and resonance of music.

Developed with this vision in mind, the A&ultima SP3000T channels the profound emotion and lasting essence of analog audio. The integration of a real vacuum tube creates an authentic analog sound complemented by cutting-edge audio technology such as TERATON ALPHA for an immersive auditory experience.

Introducing the A&ultima SP3000T — a portable audio player that defies convention, offering a unique fusion of analog and digital excellence.

TRUE ANALOG SOUND WITH REAL VACUUM TUBE

The original vacuum tube is known for its warm sound, attributed to its distinctive rich harmonics. 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 A&K’s unyielding quest for innovation and refusal to compromise, they worked to bridge the gap between stationary and portable audio by infusing the essence of analog sound. These efforts eventually culminated in the pairing of the SP3000T with the RAYTHEON JAN6418 miniature vacuum tube, a mini vacuum tube popular among audiophiles. Designed to meet military specifications and traditionally used in military communication gear, it quickly garnered recognition for its distinctively warm and soft sound, leading to its integration into regular audio devices.

SOUND CRAFTSMANSHIP FOR THE ULTIMATE VACUUM TUBE SOUND

Due to inherent differences in noise and amplification in original vacuum tubes, Astell&Kern adopted the meticulous selection process of carefully and precisely measuring and pairing each JAN6418. This 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. And thanks to their unwavering dedication to craftsmanship, A&K has successfully brought the distinctive spatial sense and balance found in their existing players into the analog realm of vacuum tube sound.

MINIMIZING MICROPHONIC NOISE

The integration of vacuum tubes into compact, portable devices presents a formidable technical hurdle: maintain low noise level while delivering resolution and robust output. This challenge was tackled in the SP3000T with a custom-made solution designed to minimize microphonic noise, even during minor shocks or vibrations.

  1. Independent modular, flexible PCB design-engineered separately from the main PCB
  2. Silicone case designed to absorb primary shocks from the vacuum tube
  3. Silicone tubing tailored to the vacuum tube leads to reduce shock transmission
  4. Silicone dampers around the vacuum tube suspend the tubes in the air

TUBE CURRENT OPTION

A&K 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 IEMs as you fine-tune the current of the tube amp.

While in vacuum tube mode or hybrid mode, the vacuum tubes on the back of the SP3000T emit light, enhancing the device’s subtle and stylish analog feel.

*Please note the tubes do not light up when the device is in OP AMP Mode.

A&K TRIPLE AMP SYSTEM

Harnessing the power of Astell&Kern’s unique TERATON ALPHA technology, the A&ultima SP3000T achieves seamless harmony between the rich, authentic analog sound of a real tube and the dynamic clarity of an OP AMP. The SP3000T offers three distinct modes to cater to your audio preferences:

OP AMP Mode
Unparalleled high resolution and dynamics that faithfully reproduces the original sound without distortion – an Astell&Kern hallmark sound.

TUBE AMP Mode
The authentic essence of analog sound, nothing compares to the warm texture and distinctive sense of space delivered by a Tube Amp. Enjoy the smooth and inviting analog sound unique to real vacuum tube technology.

HYBRID AMP Mode
Departing from the traditional Vacuum Tube AMP and OP AMP modes, the SP3000T features a groundbreaking HYBRID AMP mode that seamlessly blends the best of analog warmth and high-resolution output to create a unique tonal experience. With five adjustable levels, tailor your sound for an optimal listening session.

NEW VU METER GUI

The SP3000T marks a milestone for Astell&Kern as the first device to feature a VU Meter GUI, providing a visual representation of sound levels as you indulge in your favorite music.

The VU Meter, an iconic piece of audio equipment with a long-standing history, displays voltage levels of voice signals to aid volume measurement and adjustment. Beyond its utilitarian function, the VU Meter’s unique design and retro charm help to enhance the immersive music-listening experience.
