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. Equipped with the portable-friendly dual-triode KORG Nutube, which features 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.
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.
The SP2000T is 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.
