Enjoy The Sound, AK300. 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.
AK4490's Single DAC-DAC, DSD-to-PCM Playback, Parametric EQ with 20bands 0.01dB, 200 Femto Second VCXO Reference Clock, Exceptional Expandability, DLNA-based AK Connect App and Metal Touch Sensor Home Button.
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. * 32bit, 384kHz is downsampled to 24bit, 192kHz, and 32bit, 352kHz is downsampled to 24bit, 176kHz for playback. * DSD 64/128 is converted via DSD-to-PCM to PCM 24bit, 176kHz for playback.
A parametric equalizer (PEQ*1) 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. This frees up CPU cycles previously needed for calculating graphic equalizers (GEQ), allowing more detailed and accurate calculations via the dedicated DSP. The audio DSP expands the existing 10-band, ±0.5 dB graphic equalizer (GEQ*2) to 20-band, ±0.01 dB to more precisely adjust the frequency and gain (dB) as well as more accurately specifying the frequency range via Q value adjustments.
The AK300 supports USB DAC functionality. 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 Dual-DAC is able to deliver richer audio of outstanding soundstage and resolution well beyond the limits of a built-in sound card. * When using the AK300 as a USB DAC, its PEQ settings are not applied, and output up to 24bit, 96kHz is supported. * DSD 64/128 is converted via DSD-to-PCM for playback._
The AK300 can be expanded to a variety of devices through the micro-USB and balanced audio out ports located at the bottom of the product. It can be connected with the AMP as well as professional high-impedance headphones for high output and USB for data transfer and charging. It can also be connected to the Cradle for balanced audio functionality as well as the CD-RIPPER to conveniently rip audio CDs.
