Denon AVR-S670H
Score: 73/100Rankings
The Yamaha RX-V6A is a 7.2-channel network AV receiver delivering 100 W per channel, advanced 8K/60 Hz and 4K/120 Hz video support, and immersive Dolby Atmos/DTS:X sound. Its drawbacks include occasional HDMI audio glitches, a less-than-stellar DAC, and a confusing remote interface. Best suited for home-theater enthusiasts who prioritize future-proof video and multi-room streaming over audiophile-grade source listening.
The Denon AVR-S670H is a compact 5.2-channel receiver delivering 8K video, HEOS streaming and Audyssey calibration. Its modest 75 W power and limited channel expansion are trade-offs for the affordable price. Best suited for small-to-medium rooms where future-ready video is a priority.

Professional reviewers commend the RX-V6A for its clean, high-headroom amplification, extensive 8K/4K video capabilities, and Yamaha-specific features such as MusicCast and YPAO. However, they consistently note the under-whelming DAC performance and occasional HDMI reliability issues, suggesting it excels as a power-focused home-theater unit but falls short for audiophile-level source listening.
Everyday owners praise the receiver's powerful sound, easy app-driven setup, and future-proof video support, especially for gaming and streaming. Recurring complaints focus on HDMI audio glitches, slow input switching, and a confusing remote/manual, indicating solid overall satisfaction tempered by usability hiccups.
Professional reviewers from Crutchfield, Parts Express and B&H view the AVR-S670H as a solid entry-level option that delivers future-ready 8K video and robust 3D audio decoding, while Audyssey MultEQ and the HEOS ecosystem add real value for small-room installations.
Consumers generally praise the receiver's easy setup, HEOS multi-room streaming and the convenience of the mobile app, while recurring concerns focus on the 75 W power rating and the lack of extra channels for larger Atmos setups.
