How to Choose
When selecting a Denon receiver without a built-in amplifier, the key considerations are your desired channel count, processing capabilities, and compatibility with your external amps. If you plan a large multi-channel setup with Dolby Atmos or DTS:X, models like the AVC-X8500H or AVP-A1H with 11+ channels processing are optimal. Video support is critical too—look for HDMI 2.1 with 8K passthrough if you want future-proofing. Additionally, consider features like Audyssey room correction, multi-zone audio, and streaming capabilities such as HEOS integration. Finally, ensure the preamp’s inputs and outputs match your devices and amplifier configuration for seamless connectivity.
