Astell&Kern have released the newest player in their A&ultima flagship line - the SP2000T.

The A&ultima SP2000T takes inspiration from the Astell&Kern current flagship - the SP2000 - by building upon many of the premium features plus new features never before seen in other Astell&Kern players.

New features debuting for the first time in the portable player line include the first Astell&Kern Quad-DAC player, a new triple amp system and replay gain.

SP2000T is the first Astell&Kern quad-DAC player, featuring four (4) ESS ES9068AS DAC chips, allowing the player to produce a more balanced, detailed sound signature. MQA hardware rendering is built into the ES9068AS DACs and support MQA 8x rendering.

Another first, the SP2000T introduces next-generation Astell&Kern amp technology, the Triple Amp System. Users can select between tube amp mode, normal op-amp mode or the new hybrid amp mode that uses both the tube and op-amps to provide the best sound output for the type of music you are listening to.

All three modes are available when using the 2.5 mm, 3.5 mm or 4.4 mm outputs.

Rounding out the new features of the SP2000T is Replay Gain, which allows the player to automatically adjust the volume between tracks and maintain a consistent playback level.

A full HD (1920x1080 resolution) touch screen provides a high-resolution display.

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. Equipped with the portable-friendly dual-triode KORG Nutube, the TUBE AMP mode offers a reliable continuous playback time of approximately 30,000 hours. It features an anode grid filament structure which 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 - a first for digital audio players - enhances the resolution and clarity of the existing OP AMP mode to express more musical detail, combining 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, with the new SP2000T.
