Our Take

SP2000T stays true to our philosophy of delivering the original audio experience without compromise, for the first time you'll have access to enhanced amp technology that allows you to select your preferred sound profile and take acoustics to a new level!

“T” Stands For

The "T" does not stand for a specific word, but rather encompasses design approaches and directions made during the development process!

  • "T" for the true sound philosophy
  • "T" for triple amp system
  • "T" for timless Value
  • "T" for vintage vaccum tube amplifer

The Technology

The Next Generation of AMP Technology

SP2000T exceeds the standard approach to amplification by giving you a selection of options suitable to the music your lsitening to.

With TUBE Mode utilizing a dual-triode KORG Nu-Tube, OP AMP mode utilizing A&K's TERATON Alpha technology and Hybrid mode you can switch between the uniquely warm musical TUBE sound, the extreme clarity and dynamics of OP AMP mode or enjoy enhanced clarity, resolution and musical detail with HYBRID Mode. Brand new to Digital Audio Plyaers, SP2000T's Hybrid mode offers five individual options within itself mixed and matched with optimal ratio's of OP AMP and TUBE AMP to present you with a new perspective and choice for perfecting sound characteristics.

The SP2000T TUBE and HYBRID Modes supports all output-types, 2.5mm balanced, 3.5mm single ended and 4.4mm balanced, with no restriction on the type of plug utilized. Allowing you to enjoy the unique characteristics of this circuit with a wider variety of existing headphones in your collection!

Internal Mechanical Designed to Minimize Noise

SP2000T features a special design tailore made to minimize tube microphonics. Multiple design iterations and verifications have been performed over a long period of time to ensure that any and all strucrual issues were addressed. In the end to minization mechanical vibrations both sides of the KORG Nu-Tubes are fixed with a flexible silicone cover and a modularized mount that is physicaly seperate from the PCB board. Plus to further reduce the possibility of noise a structure was devised to use magnetic forces to float the amp in the air.

Additionally A&K SP2000T has a hyper-pure silver plated sheild can to protect the audio block from noise and electromagnetic interference during operation. Creating perfect sheilding that provides excellent audio performance.

Quad-DAC Perfection

SP2000T comes equipped with four ESS Sabre ES9068AS DACs with two DACs per channel for dedicated deocding, allowing SP20000T to achieve a more deatiled and balanced sound with greater depth and spatial realism.

Wireless Hi-Fi

BT Sync function connects SP20000T to an external device via bluetooth allowing for high-quality playback. You can also use AK File Drop for quick and easy wireless file transfers with a PC, Smartphone or FTP program located on the same network. Finally dual-band wifi support (2.4/5 Ghz a/b/g/n/ac) allows users to enjoy streaming services with enhanced network performance and stronger more reliable network reception!
