AT A GLANCE
Top-drawer room correction
Bounteous custom features
Bluetooth requires accessory
The Denon AVR-4520CI and Audyssey MultEQ XT32 room correction combine to produce a close to perfect-sounding receiver.
Denon and its sister brand Marantz are among the most popular A/V receiver makers. The AVR-4520CI is Denon’s top-of-the-line model, the brand’s best shot at building every feature worth having into a nine-channel powerhouse. It does not attempt to be all things to all people (Bluetooth users, for instance). But it does offer a feature set that is strong in custom integrator features; hence the CI designation in the model number. And, as I discovered in this review—you won’t mind if I give away the ending, will you?—it also offers the best implementation of Audyssey room correction I’ve ever heard. Room correction has always seemed like a great idea, but the results have been hit or miss. Here it consistently produced great sound.
