Accuphase DP-750 User Manual

The new DP-750 is succession model of DP-720 launched in
2013.
DP-750 is the superlative integrated SACD/CD player that
reflects great technologies of the DP-950/DC-950 combo,
aiming for the best performance and sound quality.
Newly developed SACD/CD drive is equipped, with effective
control of vibrations, they are completely shut off from the
power transformer to the optical pick-up, and the operating
motion noise is also dramatically decreased.
The superb low distortion and noise performance exceeding
the former model allows DP-750 to dynamically express
even the sonic purity and emotions of music.
The DP-750 is dripping with Accuphase cutting-edge digital
& analog technologies, and offers the full enjoyment of music.
