Accuphase DP-450

Accuphase has spent 35 years developing CD players in pursuit of the best in disc playback. The DP-450 CD player combines a number of innovative technologies, including a CD drive mechanism with a strong integrated structure, high-quality elastic dampers that protect the lensactuator from vssibration, and MDS+ type D/A converters with four parallel circuits. The DP-450 extracts the full potential of any CD to deliver a listening experience that stays with you.

• High-grade CD drive.
