Pure Sound
A common factor in devices operating in AC power is that the AC power supply is a point of entry for unwanted external noise and exit for device noise. These are the main causes of sound quality degradation.

The AK500N does not allow even 1% of external noise.

Although the AK500N is desktop audio device, it was designed to use a built-in battery for noise isolation. The AK500N physically blocks noise generated in the AC power supply to prevent sound degradation at all levels. Music playback on the AK500N is achieved with battery-only operation, creating a truly Pure Sound.

The SMPS (Switched Mode Power Supply) employed in the AK500N is an outstanding device with a Level 5 efficiency rating. The noise-sensitive power ripple noise* is below 50mVp-p at full load (5A).

The AK500N delivers sound quality closest to the original recording through perfect noise isolation and battery-only operation.
* Ripple Noise : Unwanted "ripples" of direct current (DC) voltage in the alternating current (AC) peaks resulting from the incomplete conversion of AC to DC.

The AK500N features a dedicated DSD chipset for DSD playback and converts PCM file to DSD64 data through audio engine of Astell&Kern.
The AK500N converts high-resolution 32 bit/384 kHz WAV PCM and 24 bit/352 kHz FLAC PCM file to DSD64 data without any down-sampling.
In Addition, real time PCM file to DSD64 data playback available.

Go one step further to original sound with this feature by converting, without any distortion, the unique audio information contained within the sound source.
