About Denon AVR-S660H 5.2 Ch AVR - 75 W/Ch (2021 Model)
90% highlighted the user interface
The app makes it easier for me to set preferences like HDMI input names, movie/music profiles, etc.
92% found the sound quality exceptional.
I like the quality of sound and sound balance produced by the receiver with my existing speaker system.
95% were impressed with the power output
The power output is not the highest on the market, but I still get great output and very nice sound.
85% were satisfied with the connectivity options
I can easily access my entire collection, internet and SirusXM through the HEOS app and HEOS built into the unit.
I have a product that is 8K ready and upscales to 4K, which is rare for A/V receivers.
90% found it compatible, but 10% didn't
I bought this model because it has dual optical inputs and binding posts for all non-subwoofer speakers.
I used high end 8K HDMI cables to plug everything into the back of the stereo and from the stereo to the TVs ARC input, but it stopped displaying anything.
I was able to connect my Samsung S9 via bluetooth and enjoy audio previously. However, now it doesn't work and my phone is unable to connect via bluetooth.
