Design

The AVR-4308CI uses a 7-channel equal power discrete amplifier design and Advanced AL24 processing for enhanced audio resolution. It was among the early AV receivers to integrate TCP/IP networking, so a traditional receiver gets real network features. HDMI 1.3 handles high-definition audio and video, and the built-in Wi-Fi and HD Radio cover internet radio and streaming.

Context

The AVR-4308CI was part of a new line of Denon AV receivers unveiled in 2007, positioned above the $1,600 AVR-3808CI. In some evaluations it outperformed the higher-numbered AVR-5308. Denon already had a reputation for high-quality A/V receivers, and the 4308CI added advanced networking and multi-zone capabilities.

Market

Some users have reported the AVR-4308CI cutting out during high-volume playback or dynamic audio scenes, with potential issues linked to the left/right DAC affecting preamp outputs. Failures in Zone 2 functionality have also been reported. The original price was $2,500, yet units have turned up in thrift stores in mint condition for as little as $30. Complete systems including speakers have been listed around $550.
