In terms of the SACD audio source of the Japanese Accuphase, the highest level is of course the split DP-1000 ** device and DC-1000 DAC, which decodes the DSD through the exclusive HS-Link, but if you want to choose a relatively simple all-in-one machine, then the high-end one is this DP-770 SACD ** device.
Over the years, Accuphase has always maintained a steady pace, gradually updating its own products, this DP-770 SACD is the successor model of the previous DP-750, the product cycle is five years apart, the update speed is not fast, if in terms of data specifications, there are two improvements, one is the overall harmonic distortion, reduced by 00001% from 00005% to 00004%, the signal-to-noise ratio has been reduced by 1 dB, from the original -120 dB to -121 dB, the book number does not look amazing, but it is really very difficult to achieve the low distortion rate and high signal-to-noise ratio of the original DP-750, and the DP-770 SACD will be further strengthened.
In the SACD reading mechanism of the DP-770 SACD, AccuPhase is reinforced on top of the housing, plus a heavier upper cover, and the tray is mounted on an 8 mm chassis, and the overall mechanical structure is made of heavier materials, so that the weight of the whole machine is increased by 03 kilograms, the evolution of these mechanical structures, is to move towards the ultimate in perfect pick-up of digital signals.
The DP-770 SACD has obvious evolution, including a human-machine interface, the panel can directly display the decoding sampling frequency, whether it corresponds to SACD or USB input DSD digital files, it will be displayed on the panel, at a glance.
All of AccuPhase's designs have their own performance data, such as MDSD multi-speed control, which can be reduced from -106 dB to -108 dB with 8 DAC chips with 8 dDS++.
The DP-770 SACD also has volume control, so if you want to play with digital sources straight into the back amp, this top-of-the-line SACD** device will get you right in one step.
