The A & Ultima SP1000M is equipped with two AK4497EQ DACs. A separate DAC is dedicated to each independent left and right audio channel, producint a wider soundstage and better stereo separation. With the addition of an Octa-Core CPU, the A & ultima SP1000M not only boots faster, but is able to process digital audio playback without lag or compromise in sound.
Equipped with a 4.1 inch, HD-resolution screen, the A & ultima SP1000M provides sharp images and vivid colours to display album art, music playback and player information. The redesigned, music-centric GUI that debuted on the full-sized SP1000 is also used on the SP1000M. USB Type-C 3.0 support allows data transfers that are twice as fast as other Astell & Kern players. The A & yultima SP1000 also provides 10 hours of music playback and includes support for fast charging.
