Accuphase DP-80L

Commentary

A CD transport designed to prevent interference and unwanted radiation from digital signals and high-frequency noise.

The mechanism is mounted on an aluminum die-cast frame to prevent resonance, and floating from the chassis to cut off vibration transmission, thereby minimizing external vibration to the mechanism body.

The rotating part is supported by a thick metal frame, and the whole is thoroughly strengthened against vibration.
In addition, by adopting a solid frame structure as a whole, sound quality changes due to resonance and sound pressure of speakers are prevented, and stable operation is realized.

It uses a master clock system that controls all operations with one clock.
In the conventional method, two types were used, one for digital signal processing and the other for microprocessor. Therefore, the difference between the two oscillation frequencies causes a beat, which is a cause of sound quality degradation. In the DP-80L, this beat does not occur because it controls everything with one clock.

It is equipped with two optical fiber systems based on the digital audio interface proposed by AccuPhase and established as the EIAJ standard, and a 75 Ω coaxial output.
The optical fiber has a transmission capacity of 10Mbit/sec, which, together with the attached quartz fiber, enables digital transmission with less transmission distortion and jitter. In optical transmission, the player and processor are electrically isolated from each other to prevent the inflow of unwanted noise components, thereby preventing the deterioration of sound quality.

It is equipped with a full-fledged line filter to prevent the inflow and outflow of digital noise through the power supply.

It has a simple design and the other function keys are stored inside the lower side panel.

Exterior finished with gold-style scratch hairline finish panels and natural Persimmon sideboards.

It comes with a fully functional wireless remote control.
