Staying true to our 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 music enjoyment.The SP2000T 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.
Real Balanced Vacuum Tube Amplifier
To realise the sonic flavour of a vacuum tube amp, the SP2000T is equipped with the portable-friendly dual-triode KORG Nutube. Featuring an anode grid filament structure that operates the same as a triode vacuum tube, this smaller component, consumes far less power, yet delivers the same audio with rich overtones. The Nutube also offers a reliable continuous playback time of approximately 30,000 hours with support for the player’s onboard 2.5mm, 3.5mm and 4.4mm headphone output jacks.
NEXT GENERATION AMPLIFIER TECHNOLOGY
The culmination of Astell&Kern’s rich amp design heritage and expertise, the new innovative HYBRID MODE brings together the distinctive sonic DNA of the detailed OP-AMP and expressive TUBE AMP modes, while providing five options with different mix ratios of each amp’s sound characteristics to best serve the music being played.
SPECIAL INTERNAL DESIGN
To overcome internal microphonic resonances generated by the vacuum tubes that can seriously impact sound quality, Astell&Kern’s audio engineers painstakingly designed a clever modular structure physically separate from the PCB (Printed Circuit Board). Firstly, the vacuum tubes are fixed with flexible silicone covers to minimize any mechanical vibration, while the design uses magnetic forces to float the amp in the air to reduce internal noise. Further steps are taken to eliminate electromagnetic interference caused when internal components are in operation by applying highly conductive, hyper-pure silver plating on the existing shield cans for extra defence against these sound performance-effecting disturbances.
QUAD-DAC FOR SUPERIOR SOUND
The SP2000T comes equipped with four ES9068AS DACs, with two DACs per channel dedicated for decoding. The result is a more detailed and balanced sound with great depth and spatial realism. This latest model is also the first to feature Replay Gain functionality that automatically and uniformly adjusts volume playback from sound sources up to 24-bit/192 kHz so playlists can be enjoyed throughout without reaching for the volume.
TERATON ALPHA SOUND SOLUTION TECHNOLOGY
Following on from the A&futura SE180 player, the SP2000T is the second model to adopt Astell&Kern’s patented TERATON ALPHA Sound Solution. The result of extensive research and development, it is designed to deliver audio playback close to the original sound. The onboard DAC is not the only factor that determines the quality of sound from a DAP: Power, noise, signal conversion, circuit structure all effect the sound signature. Only when each and every one of these elements are optimised, can a player produce sound as close as the music artist and producer intended. TERATON ALPHA technology, effectively removes power noise and provides efficient power consumption and amplification right through to the audio output interface stage where the digital-to-analogue signal conversion (DAC) takes place – audio technology Astell&Kern has consistently developed and perfected over the years.
Alongside with improved dual-band Wi-Fi support, the SP2000T features AK File Drop for easier wireless file transfers. Users can wirelessly transfer files through a PC, smartphone, or FTP program located on the same network to make music management even more convenient. The new BT Sink function connects the A&ultima SP2000T to an external device, such as a smartphone, via Bluetooth, enabling music to be played back in high-quality on the Astell&Kern player. Elsewhere A&ultima SP2000T boasts Bluetooth® 5.0, providing greater range and a more stable wireless connection to headphones and, along with support for 24-bit aptX™ HD and LDAC codecs, offers the best possible wireless sound quality.
FULL HD DISPLAY
Album artwork pops from the screen with the A&ultima SP2000T boasting a full HD display. This 5-inch touchscreen packs a 1920x1080 pixel resolution, 16.7 million colours and 441 PPI, resulting in a clean and sharp user-interface design.
Real-Time Playback and AMP Mode Information LED
Through the softly dispersing LED light, Users are notified of the bit depth information of the song being played or the current AMP mode. * LED light may be turned on or off in the user settings, and one can choose between the sound source information or AMP mode information displays.
