Find Your Optimal Sound

Staying true to the philosophy of delivering original audio experiences without compromise, Astell&Kern strives to design DAPs that reach beyond the capabilities of standard playback devices to enhance the listener’s music enjoyment.

The SP2000T combines the Op Amp configuration of the SP2000 with a nostalgic vacuum tube amp, adding a vintage feel to the portable player.

Triple AMP System, the Next Generation

The SP2000T exceeds the standard approach to AMP Mode selection, based on your preferred type of music. Select between TUBE AMP mode, OP AMP mode, or the brand new HYBRID AMP mode.

Op Amp
Delivers extreme clarity and dynamic sound.

Tube Amp
Provides a uniquely warm and musical sound.

Hybrid Amp
A first for DAPs, it enhances the resolution and clarity of the existing Tube Amp mode to express more musical detail and combines the advantages of retro-analog performance and high-resolution for a new combination of sounds.

New combinations of sounds can be enjoyed in Hybrid Amp mode with up to 5 options mixed and matched with optimal ratios of Op Amp and Tube Amp settings, presenting users with new choices for their perfect sound characteristic.

Real Vacuum Tube

Equipped with the portable-friendly dual-triode KORG Nutube, the SP2000T offers a unique tube sound. Nutube offers a reliable continuous playback time of approximately 30,000 hours. It features an anode grid filament structure, is much smaller, consumes far less power, but delivers the same audio with rich overtones.
