The latest AK4497EQ dual-DAC design and the upgraded CPU in the SP1000 allows for accurate playback of native 32bit/384kHz audio with no compromise on sound quality. The music is played back, bit-for-bit, just as the artist and engineer intended for it to be heard. The SP1000 also supports native bit-to-bit DSD playback up to 11.2MHz for the best sound possible. Traditional audio has suffered from noise and distortion as power output is increased. Astell&Kern's advanced audio design and signal management technologies used in the A&ultima SP1000 brings more power output with less noise and minimal distortion. Independent DACs for the left and right audio channels provide a wider soundstage and better stereo separation. Each AK4497EQ DAC provides rich and vivid audio reproduction, allowing the listener to enjoy the sound as it was meant to be heard. The A&ultima SP1000 is equipped with an octa-core CPU which allows the player to produce the exact musical detail present in the original recording without distortion and provides a quick, lag-free operation. The A&ultima SP100 features faster booting times, speedy file transfers, lag-free processing and a new intuitive user interface for the ultimate player experience. The A&ultima SP1000 features a revamped interface design which provides music playback from the home screen to give users a more music-centric experience. By placing the power button on the volume wheel located on the side of the SP1000 instead of on the top, users can control the volume and turn the LCD screen ON/OFF, all with one simple control. Next generation USB Type-C support allows file transfer speeds up to 10Gbps and supports both data transfer and charging from the same cable. USB 3.0 protocol transfers data twice as fast when compared to other Astell&Kern players. Charging with a fast charger (at 9V/1.67A) takes only two hours and allows up to 12 hours of continuous playback. Color: Copper
