Denon DRA-550 receiver

A blend of convenience and performance for the Age of Digital Audio; Denon's Powerful DRA-550 Receiver

The DRA-550 combines the convenience of tuner/amplifier integration with the high performance of separate components. It easily handles the demanding dynamics of today's digital and hi-fi video sources through the extensive use of highly advanced circuitry in the amplifier section. The tuning section outperforms many separate tuners in both sensitivity and fidelity. The DRA-550 redefines what audiophiles have come to expect from a receiver.
