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.

- Page 1 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...
- Page 2 DP-750 can show the sampling frequency and the number of effective bits of all input signals on the front display. Quantization bits are counted directly from raw data by using a high speed Field Programmable Gate Allay.
- Page 3 The dimension of DP-750 is as same as those of DP-720. The weight becomes slightly heavier than DP-720. This is due to the long and heavy bridge dedicated to the new SA-CD drive mechanism.
- Page 4 The Bridge cover of SA-CD drive mechanism is bigger and longer than the former model. Outer rotor brushless DC motor is installed at the spindle to drive the discs. This is very effective for reducing the motion noise from motor drive and air flow by disc rotation. Furthermore, laser pick-up module is mounted with vibration absorbers.
- Page 5 DP-750 applies the systematical layout. Each circuit block is logically placed to make the signal path short as possible. The digital circuit with DAC chip is on the right side, and analog circuit equipped with glass cloth fluorocarbon resin PC board is on the left side at the back panel side.
- Page 6 Ultra Low Noise is one of the main technical features of DP-750. The former model, DP-720 has the excellent noise performance, however, DP-750 achieves another 18% lower output noise voltage.
- Page 7 DP-750 proudly shows the great THD+Noise characteristics which are quite important for sound quality. DP-750 makes an almost flat response from the low frequency through to the high frequency, and it obtains less than 0.0002% THD+Noise in all frequency bands.
- Page 8 For D/A converter section, for DP-750, Accuphase updates the DAC chip to ESS Technology’s 32bit Hyperstream Ⅱ DAC ES9028PRO. ES9028PRO has 8 DACs inside, and DP-750 uses the 8 DACs connected in parallel per channel with Accuphase unique technology, MDS++ conversion system.
- Page 9 The ratio between the signal and conversion errors increases, So the converter performance is improved. The improvement degree works by a square root of the number of DACs. In DP-750, all performances are improved by a factor of 2.8.
- Page 10 The point of MDSD is the delay elements. DSD signal in DP-750 is D/A converted with half-delayed clocks and is combined when it comes to the output. As the analog output becomes half-clock time resolution, it allows the signal to work as the double speed operation.
- Page 11 DP-750 has 4 digital inputs, Coaxial, Optical, HS-LINK and USB. USB Input accepts 384kHz/32bit-PCM or 11.2896MHz-DSD. DSD data can be received both DoP（DSD over PCM）and ASIO2.1 (11.2896MHz: ASIO only). HS-LINK has been evolved into Version2. Original HS-LINK(Ver.1) transmits and receives only 192kHz/24bit-PCM or 2.8224MHz-DSD, but Ver.2 comes...
- Page 12 HS-LINK Version 2 extends the HS-LINK standard. For backward compatibility, DP-750 is still available HS- LINK Ver.1 output.
- Page 13 The biggest feature of HS-LINK Ver.2 is sending the music signal and the master clock separately to D/A converter in a receiver. HS-LINK Ver.1 sends the music signal merging the master clock together, PLL circuit for master clock recovery is needed at receiver side. Since master clock is been transmitting as it is, in HS- LINK Ver.2, not only master clock recovery is unnecessary at receiver side but it comes to be free...
- Page 14 DATA Disc playback is available. You can record music files on blank DVD by using your PC. DP-750 can play 192kHz 24 bit data of WAV, FLAC, AIFF format, and 5.6MHz 1bit DSD data also. You can enjoy all kinds of digital data with DP-750.
