Overview
The DP-720 is an integrated player that reflects the superb know-how of the DP-900/DC-901 combo, aiming for top performance in the integrated category. As appropriate for a high-end player, the DP-720 features the latest versions of major Accuphase in-house developments: a high-precision drive and an advanced MDSD type D/A converter. The high-precision drive inherits vital know-how and technology from the DP-900, realizing the ideal transport design for bringing out the full potential of the SA-CD medium. The ultra-heavy, high-rigidity, high-precision mechanism has been finely honed to further perfection. The digital processor section is optimally suited to handle the SA-CD format, using cutting-edge circuit topology and advanced digital technology to further enhance the innovative MDSD (Multiple Double Speed DSD) principle for direct D/A conversion of the DSD signal.
