It is also capable of handling DSD audio, as the device is outfitted with an AK4490 chip that converts DSD directly to PCM playback, thus skipping the DSD to WAV stage that usually occurs prior to analog conversion in common portable DSD players. The AK300 can be controlled via its 4.0" WVGA touchscreen, and offers 64GB of internal storage while supporting microSD cards up to 128GB. Thanks to its streaming capabilities over Wi-Fi and Bluetooth, you are not limited to playback of songs you have on your device. 24-Bit / 192 kHz Bit-to-Bit Playback The AK300 is capable of bit-to-bit playback up to 24-bit / 192 kHz. 32-bit audio is down sampled using a sample-rate converter (SRC). In addition, DSD 64/128 can be played back via conversion to PCM. PEQ (Parametric EQ) A parametric equalizer is implemented in the AK300 to deliver detailed adjustment of the original sound. An audio digital signal processor (DSP) aids in this process, freeing up CPU cycles from calculating graphic equalizers (GEQ), and thus, allowing more detailed and accurate calculations via the dedicated processing. The audio DSP allows for a 20-band, ±0.01 dB equalizer to more precisely adjust the frequency and gain, as well as more accurately specifying the frequency range via Q value adjustments. High-res audio in your hand Astell & Kern AK300 Seriously into music? The Astell & Kern AK300 portable music player delivers your high-resolution digital audio files with rich, detailed sound. When you use a great set of headphones with the AK300, you can experience sound that can rival a home hi-fi system. The AK300 can also serve as a stand-alone digital-to-analog converter (DAC) for high-resolution sound from files stored on a computer, thanks to its USB digital input. Extraordinary sound quality The AK300 uses a high-quality DAC capable of decoding sampling rates up to 24-bit/192kHz. Even with lossless files or compressed formats like MP3, the AK300 can help your music sound its best. Its high signal-to-noise ratio and low distortion let the subtle details of your music come through. Its high-fidelity, low-impedance output gives your headphones more power than most portable music players, for excellent performance. Touchscreen and push-button controls The player's color touchscreen is simple to navigate. A metal touch sensor button gets you back the home screen with just a tap. And it displays artist and title info as well as album artwork. And because this is a high-resolution audio player, the AK300 features an analog volume knob, so you can make small, nuanced adjustments. Expandable memory To add music to the AK300, connect the player to your computer with the included USB cable. Then just drag and drop your selections to the player while its built-in battery charges. The AK300 comes with 64GB of internal memory and a microSD card slot lets you expand the storage up to 128GB.
