Across 22 YouTube reviews, the Denon AVR-S660H earns an Index score of 4.4/5, ranking #20 among AV Receivers. Reviewers most often praise its features, connectivity, other, while the most common criticisms concern sound quality, power/performance.
The Denon AVR-S660H is widely praised for packing modern video and gaming-ready features into a mid-range AV receiver, with reviewers repeatedly citing its 8K/60Hz and 4K/120Hz HDMI pass-through, HDMI 2.1 features (VRR, ALLM, QFT), and broad HDR support (Dolby Vision, HDR10/ HDR10+, HLG). Many reviewers also highlighted strong connectivity and streaming options — six HDMI inputs with multiple 8K-capable ports, eARC, built-in Wi‑Fi, Bluetooth, AirPlay 2 and HEOS multi-room streaming — and voice assistant compatibility, noting these features across a large portion of reviews. The AVR is commended for user-friendly setup (Audyssey/MultEQ calibration and an intuitive on‑screen setup) and solid sound and power for small-to-medium setups, including dual subwoofer outputs and support for high‑resolution audio formats. Overall, these strengths are reflected across the majority of the 22 reviews and the high number of pro mentions (248 total), especially around features and connectivity.
Criticisms focus on the AVR-S660H’s limitations as a less fully featured multichannel amplifier: several reviewers noted it only offers five amplified channels (5.2/5.2.2 limitations cited) and therefore lacks native height-channel amplification for Dolby Atmos/DTS:X, and power into all channels can drop when driving multiple speakers. Some reviewers also reported issues with higher-volume performance or a slightly grainy/brittle top end on demanding material, alongside a handful of usability and build complaints such as a plasticky remote, clunky app/menus, heating and startup noises, and limited multi‑zone capability. These negatives are smaller in number than the pros but recur across multiple reviews (41 cons total) and concentrate on sound/performance, channel count, and some usability/build quality issues.
