Product Information

Everlasting Beauty

Astell&Kern wants to make a product that delivers music that would touch people's hearts, not just their ears. Not only have they introduced the most innovative and up-to-date technology to the SP2000T for this goal, with the SP2000T Copper Nickel, they wanted to capture the characteristics of the raw materials and their unique beauty to complete our philosophy and design values. Existing flagship models that utilize copper material are praised by audiophiles for the most musical representation of the instrument’s original sound. This limited edition of the SP2000T is made of an alloy of copper and nickel which is used in wind instruments and is known for creating deep, full sound. Not only is the design more refined, but it has a very high corrosion resistance, which is a property of copper-nickel alloy, giving it long-lasting beauty. In addition, with the copper-nickel alloys high electrical conductivity and low magnetic shielding, you can experience a different sound signature than the SP2000T made of aluminum. Enjoy SP2000T Copper Nickel's amazing sound experience, built with the artisan spirit to complete the perfect design for sound.

Find Your Optimal Sound

Staying true to the philosophy of delivering original audio experiences without compromise, Astell&Kern strives to design portable music players that reach beyond the capabilities of a standard playback device to enhance the listener’s musical enjoyment. The SP2000TCN combines the OP AMP configuration of our SP2000—the culmination of Astell&Kern's finest audio technology—with a nostalgic vacuum TUBE AMP, adding a vintage feel to the portable player.

Triple AMP System is the Next Generation of AMP Technology

The SP2000T exceeds the standard approach to AMP Mode selection, based on the type of music you are listening to. Select between TUBE AMP mode, OP AMP mode, or the brand new HYBRID AMP mode. OP AMP mode puts Astell&Kern's AMP technology expertise to use, delivering extreme clarity and dynamic sound, while TUBE AMP mode provides a uniquely warm and musical sound. HYBRID AMP mode - a first for digital audio players - enhances the resolution and clarity of the existing TUBE AMP mode to express more musical detail. HYBRID AMP mode combines the advantages of retro analog performance and high-resolution output, giving you the pleasure of a brand new tonal characteristic. Experience the unique sound enhancements that AMP technology has to offer.

Vacuum Tube Amplifier Compatible with 2.5mm, 3.5mm & 4.4mm Output Jacks

The SP2000T supports all output types, with no restriction on the type of receiver used, so you can enjoy the unique characteristics of the vacuum tube.

Real Vacuum Tube

Equipped with the portable-friendly dual-triode KORG Nutube, for a unique TUBE AMP sound. Nutube offers a reliable continuous playback time of approximately 30,000 hours. It features an anode grid filament structure that operates the same as a triode vacuum tube. It's much smaller, consumes far less power, and yet delivers the same audio with rich overtones.

Hybrid AMP Mode

HYBRID AMP mode, supported for the first time by a DAP, is the essence of Astell&Kern's advanced AMP design technology. New combinations of sounds can be enjoyed in HYBRID AMP mode, which is based on the OP AMP sound and the addition of tasteful warm tones unique to TUBE AMP technology. The five options mixed and matched with optimal ratios of the OP AMP and TUBE AMP present users with a new perspective and choice for the perfect sound characteristic to suit their tastes.

Special Design to Minimize Microphonic Noise

SP2000T features a special design tailored to minimize microphonics (the phenomenon wherein the vacuum tubes generate noise even from a small external impact). Multiple design iterations and verifications have been performed over a long period of time to fix the structural issues of vacuum tubes that generate microphonic noise even from a small impact or vibration. For minimization of mechanical impact and vibration, both sides of the vacuum tube are fixed with flexible silicone covers, and the vacuum tube has been modularized so it is physically separate from the PCB. Astell&Kern goes to great lengths to innovate and design these small components that make a big difference in the quality and sound of our products that no other manufacturer can match.

Separation Using Magnetic Polarity

A structure that uses magnetic forces to float the amp in the air, thus minimizing noise from the vacuum tube itself, which is generated when it is exposed to mechanical impact or vibration.

Flexible Silicone Covers & Silver Plating Shield Can

Astell&Kern products apply shield cans so that noise and electromagnetic interference, which occur when the countless parts are in operation, do not affect the audio block. The SP2000T has taken it a step further by applying highly conductive, hyper-pure silver plating on the existing shield cans for perfect shielding that provides excellent audio performance.

AK Ultimate Sound Solution, TERATON ALPHA

TERATON ALPHA is AK's ultimate Sound Solution to produce audio playback that is close to the original sound through the audio output interface by use of effective power noise removal, efficient power management and amplification with minimal distortion. TERATON ALPHA features Astell&Kern's patented technologies, which are the result of tens of thousands of hours of continuous research and development to produce sound close to the original sound the artist and producer intended.

Adoption of Full HD Display for Improved Image Quality

The SP2000T features a full HD screen to provide a higher quality display.

Quad-DAC for Perfection of Superior Sound

The SP2000T is equipped with four ES9068AS DACs, allowing two DACs per channel for dedicated decoding. The SP2000T achieves a more detailed and balanced sound with great depth and spatial realism.

Replay Gain Automatically and Uniformly Adjusts Playback Volume

Replay Gain, which adjusts sound sources with different volumes to an identical level, has been applied. Now, enjoy your own playlists seamlessly through the Replay Gain feature on the SP2000T.

Dual-Band WiFi (2.4/5 GHz)

Dual-Band Wi-Fi is supported for users who enjoy streaming services, providing enhanced network performance. With streaming music services becoming more popular, stronger and more reliable network reception becomes even more important for your audio experience. The SP2000T supports Dual-Band Wi-Fi (2.4/5GHz, a/b/g/n/ac).

AK File Drop to Enjoy Wireless Transfers

The new AK File Drop function in the SP2000T makes file transfers easier and more convenient. Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program located on the same network. Music file management is now possible with a cableless, wireless solution.

Wireless Hi-Fi Sound Through BT Sync

The newly introduced BT Sync function connects the SP2000T to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker. Music from an external device, such as a smartphone can now be played back in high-quality on the SP2000T using the BT Sync function. Real-Time Playback and AMP Mode Information Reflected by Light. Through the softly dispersing LED light, users are notified of the bit depth information of the song being played or the current AMP mode.
