Compact Size, Limitless Sound
The A&ultima series continues to present advanced and innovative technology and the standard of perfect sound.
We renewed our commitment to this goal and began to delve deep into the concept of true portability with unrivaled performance and unmatched sound performance.

The process was not easy; we had to overcome numerous unending challenges in keeping the perfect sound performance on par with SP3000 while reducing the device’s size. We began the development of an audio device that is smaller and lighter, while still delivering perfect sound. After dozens of changes were made to the circuit, we finally present you with the SP3000M.
The innovative Hexa audio structure separates digital and analog signal processing and independent dual audio circuit for unrivaled audio performance SP3000M offers all these features in its lighter, compact design allowing you to enjoy incredibly vivid sounds you will not experience anywhere else.

A true Hi-Fi portable audio player with the best audio performance and equally sophisticated design, the SP3000M offers all of this in the palm of your hand.

Stunning Audio Performance with Independent Dual Audio Circuits
In order to create a truly innovative DAP, not just a great DAP, we tried to overcome the limitations of sound by envisioning an independent dual audio circuit that has never been attempted by anyone featuring a HEXA structure with unbalanced and balanced outputs.

Almost all other DAPs, including Astell&Kern, use an internal DAC for both unbalanced and balanced outputs. Since the signal from the DAC is divided into unbalanced and balanced then delivered to the AMP, an Audio Switch is essential. However, when using a switch, there is a limit to the range that can receive the signal sent by the DAC, so most DAPs reduce the signal size first and then when the signal is transmitted back to the amplifier, it is necessary to restore the original signal size. This causes a limitation in improving the audio performance.
 
To overcome the limitations, our engineers designed a HEXA structure using two AK4191EQs and four AK4499EXs, creating an innovative unbalanced and balanced independent dual audio circuit design. As a result, the SP3000M achieves a SNR of 130dB, the best of any DAP available. You can feel the clean, pure delicacy of sound with the SP3000M that you can't experience in any other DAP.
