Popular reviews on Denon Receivers:

Denon AVR-X4400H AV Receiver:

The Denon AVR-X4400H provided solid performance with both music and movies. I was particularly impressed with the Denon’s performance with multichannel movie soundtracks.

Even with seven channels of amplification in use with complex soundtracks at relatively high volumes, the Denon remained composed, without any signs of clipping or strain. The AVR-X4400H’s combination of full feature set, solid performance and the all-important ease of use makes it an excellent competitor in this segment of the AV receiver market.”

-Brian Kahn,

Denon AVR-S730H

The AVR-S730H is among the least expensive receivers with this level of features, including 4K/HDR compatibility, multiroom music, Dolby Atmos and DTS:X. Sound quality is very good with both music and movies, regardless of the speakers we used. Auto calibration worked well.”
