Compact high-res digital audio player. While succeeding the state-of-the-art DAC and scalability as applied to the AK380 and AK320, the latest model has improved accessibility by being priced at a reasonable level. AK300 is capable of bit-to-bit playback up to 24bit, 192kHz. 32bit audio is downsampled using a sample-rate converter (SRC). In addition, DSD 64/128 can be played back via conversion to PCM. A parametric equalizer (PEQ1) was implemented in the AK380 to deliver detailed adjustment of the original sound, and an audio digital signal processor (DSP) was added to aid in this process. Astell&Kern implemented a voltage-controlled crystal oscillator (VCXO) high-precision clock with a reference jitter value of 200 femto seconds3. Femto clocks are commonly used in high-end audio systems, and the clock is measured in high-precision femtosecond units (one quadrillionth of a second). The AK300 can be connected to a PC or Mac via USB for use as a USB DAC that supports PCM/DSD. When playing back music stored on a PC or Mac, the Single-DAC is able to deliver richer audio of outstanding soundstage and resolution well beyond the limits of a built-in sound card. Astell&Kern has further enhanced DLNA functionality via the AK Connect app. Wireless networking DLNA (version 1.0) connects to a NAS or PC, and is easily controlled with a smartphone or tablet through AK Connect. Frequency response: +/- 0,075 dB (20 Hz - 20 kHz) // +/- 0,56 dB (10 Hz - 70 kHz). Max. SPL: 116 dB / 1 kHz. Impedance: 1 / 2 Ohm. Dimensions 75,15 x 112,4 x 15,45 mm. Weight: 205 g.
