Find your optimal sound

The newest member of the A&ultima series, the SP2000T builds on the class-leading sound of the A&ultima SP2000 and is the first player to feature an innovative Triple Amp System allowing music fans to switch between the different sonic characteristics of a normal OP-AMP (operational amp) mode, a vacuum TUBE AMP and a HYBRID AMP mode that combines the tube amp’s warm analog performance and the Op-Amp’s high-resolution clarity.

SP2000T

Next generation amplifier technology

Boasting the most advanced amp technology of any portable player, SP2000T owners can toggle between three-amp modes to find the optimal sound to suit the music they are listening to. Based on the set-up from the original SP2000, the OP-AMP configuration offers ultra-clarity and a dynamic playback. Switch to the TUBE AMP mode and the uniquely warm and musical audio associated with vacuum tube amplifiers will be revealed.

Best of both amps worlds

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.

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.

Seamless playback volume

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 technology

The first player to harbour TERATON ALPHA technology that 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.
