A premium AV receiver has to do more than decode surround formats.
In a serious listening room, it must anchor the system: routing video cleanly, driving speakers confidently, adapting to the room, and leaving enough flexibility for future expansion or specialist sources.
This guide is grounded in the supplied Stereoindex source material and focuses on AV receivers and closely related components that can sit at the heart of a home entertainment system. Most entries are true multichannel AV receivers or AV amplifiers; a few are adjacent stereo, vinyl, or network components included here because they were supplied with the source set and may be relevant when building around an AV system. The emphasis is on practical differentiation: channel count, surround-format support, room correction, HDMI and streaming features, amplification approach, and system role. Where the source does not support a claim, it is not made.

How to Choose the Right AV Receiver from This Selection
Start with channel count, because it determines the kind of speaker layout the receiver can support without additional amplification.
For a compact 5-channel theater, the Anthem MRX 540 and Denon AVR-S660H are the clearest fits in the supplied material: the Anthem emphasizes ARC Genesis room correction and full-channel preamp outputs, while the Denon places more weight on streaming, HEOS, Audyssey MultEQ and broad everyday connectivity.
For immersive layouts, look at the receivers with 7.2, 9.2 or 11-channel ambitions. The Arcam AVR21 is notable for Dirac calibration and an expansion path from 5.1.2 Dolby Atmos to 7.1.4 with added power amplifiers. The Marantz Cinema 60 fits a 7.2 or 5.1.2 system and adds advanced HDMI gaming features plus a built-in MM phono stage. The Pioneer VSX-LX505 and Marantz SR6015 move into 9.2-channel territory, while the Pioneer SC-LX904 is the most expansive supplied option with 11 x 140 W into 8 ohms and four ceiling-channel support. Room correction should be treated as a major buying factor, not an afterthought. The Arcam’s full 16-channel Dirac calibration, Anthem’s ARC Genesis, Denon’s Audyssey MultEQ and Pioneer’s MCACC systems all address speaker and room interaction, but they are not interchangeable in the way they are described or positioned. If your room is acoustically difficult, give priority to the receiver whose calibration system and channel layout best match the installation. Video support matters if the receiver will sit between modern sources and a display. Denon AVR-S660H, Marantz SR6015 and Marantz Cinema 60 all have explicit 8K-related support in the source, with the Cinema 60 adding a particularly detailed list of gaming-focused HDMI functions. If those video features are less important than sound processing, amplification or room correction, the Arcam, Anthem and Pioneer models may be more relevant depending on speaker layout. Finally, separate the true AV receivers from supporting components. The Denon DP-400, Marantz Stereo 70s and Yamaha WXC-50 are not direct AV receiver alternatives in a surround system: the Denon is a turntable, the Marantz is a stereo receiver, and the Yamaha is a network player. They can still be valuable in the same ecosystem, particularly if you want vinyl playback, a stereo-first media room, or MusicCast streaming added to an existing amplifier or AV receiver.
