The perfect way to enhance both movies and gaming, the Denon AVR-S660H brings audio immersion to your home entertainment.

Truly immersive sound
Soundbars and bases offer a great step-up over your TV’s speakers but they still can’t beat the immersive sound of an AV receiver like this Denon AVR-S660H. With 5.2 channel Dolby TrueHD and DTS-HD Master Audio, you get surround sound that’s pin-sharp in detail and totally enveloping – just like at the cinema.

Ready for 8K – with three 8K HDMI inputs
Featuring three, dedicated 8K compliant HDMI inputs and a matching output, this Denon AVR is ready for the next generation of TV and gaming. Not only does the amp pass through 8K/60Hz signals, but it also upscales HDMI signals to the 8K standard, too – helping you make the most of your 8K TV with 4K UHD media.

Serious about gaming
The latest HDMI support also marks a big improvement in gaming. 4K/120Hz and VRR (Variable Refresh Rate) support maximise resolution and clarity. Quick Frame Transport (QFT) and Auto Low Latency Mode (ALLM) help eliminate lag and frame tearing, giving you a smoother, more responsive gaming experience.

Support eARC (enhanced Audio Return Channel)
As part of the HDMI interface support, eARC is now standard. This enables uncompressed audio transmission from your TV, back to the Denon receiver. This is ideal for getting the best audio from any smart TV apps and services you may use.

Supports Dolby Vision, HDR10+ and Dynamic HDR
Equipped with a flexible 6 in/1 out HDMI interface, the AVR-S660H supports a wide range of High Dynamic Range video formats. These include Dolby Vision, HDR10 and HLG. It also supports HDR10+, which enhances picture realism by sending dynamic Meta data to your TV, as well as Dynamic HDR. In short, whatever the format used by the film, game or stream, the Denon supports it.

Works with your voice assistant
The AVR-S660H is compatible with Siri, Google Assistant and Alexa, making it widely compatible with your choice of voice assistant. For Alexa or Google Assistant control, simply download the HEOS app. Pair your Echo device if you’re using Alexa and you’re good to go. For control via Siri, simply link the amp via Apple AirPlay 2 and enjoy voice interaction and AirPlay 2 multi-room support.

HEOS built-in - for the finest multi-room audio
HEOS multi-room music systems connect together by dual-band Wi-Fi, making them easy to set up with your existing home network. Up to 32 HEOS units can be set up at one time, ensuring even the largest of homes are covered for multi-room music. With HEOS already built-in, the AVR-S660H is ready to go as a single 'zone' without any further adaptors.

Control it all with the HEOS app
Once you've set up your HEOS speaker system, you can stream music effortlessly via the dedicated HEOS app. Available for Apple iOS and Android, the app not only lets you stream your stored music but also Internet radio services and popular streaming services such as Spotify, Tidal, Napster and Deezer.

Bluetooth, AirPlay 2, and built-in wi-fi for the complete networking experience
With both Bluetooth and AirPlay 2 connectivity it's easy to connect all your smartphones, tablets and compatible lap/desktops and stream music wirelessly. The AVR-S660H also comes with wi-fi and Internet radio. Simply connect to your home network via Ethernet or wi-fi and access thousands of Internet radio sites via vTuner as well as subscription services such as Spotify Connect (requires Spotify Premium account). A Bluetooth headphone output is now also standard.

Connect it all – including a turntable
As well as six HDMI inputs, the Denon also has a wide range of other AV connectivity. Older AV sources are catered for with two composite inputs. Optical digital inputs are ideal for connecting older devices, too or upgrading the sound from a compatible CD/Network music player. Two analogue inputs are perfect for hi-fi components, with the dedicated MM phono input perfect for plugging in a turntable.

Make it more entertaining, with the Denon AVR-S660H.

Rated 5 out of 5 by from Easy to get going I had this going within about five minutes of plugging in. All very straightforward. I would say that I did change things around settings wise a little latter, having done a master reset on my television.

Rated 5 out of 5 by from Awesome product at a great price I completed a lot of research before choosing a new receiver and very happy with my purchase. It’s full-featured and very easy to setup and use. Would recommend this to anyone!

Rated 5 out of 5 by from Amazing in every way I haven't bought this make before but installing it was a breeze and the sound quality is so far greater than what I had before. I'd also like to mention the staff assistance for the purchase was second to none. A wonderful experience.

Rated 5 out of 5 by from Great budget amp I bought this a couple for days ago to replace an old yamaha amp that was about 20years old. This amp was easy to set up because having hdmi instead of phono connections was far easier,sound quality softer also I liked having built in phono stage for turn table back now to playing my vinyl collection. Plenty of connections for blueray and CD player etc. A great amp for the price.

Rated 5 out of 5 by from Excellent features at a reasonable price. I was looking to upgrade an old Sony AV system that still sounded great but had no HDMI switching, I was drawn to a Marantz system that was £250 more expensive but the guy at the Norwich branch suggested I listen to the Denon, I was pleasantly surprised, things have come a long way since I bought the Sony! As usual Richer Sounds Norwich went the extra mile and set up the system for me to hear, I never buy any audio gear without listening to it first as it could be a complete waste of time for everyone. Overall a very pleasant and painless experience!

Rated 4 out of 5 by from Good receiver. Great sound. Early days, but easy to setup and sounds great. Used mostly for movies. Sound is clear and precise. The streaming networking features are really good, but a bit difficult to set up with the Denon app and Alexa. Great customer service from Richersounds.
Date published: 2022-01-29
Rated 5 out of 5 by from It works! After lots of trouble with another amp. After repeated connection problems with another amp the Denon works every time. It come with an instruction manual which for a novice like me is essential. It sounds great and does what is says on the tin.
Date published: 2022-01-22
Rated 2 out of 5 by from Great sound as expected but far too complicated! I have had this a month now and am very disappointed. I bought it as an upgrade to my Onkyo which became unreliable. Good sound is a given these days and I at least expected to get to a level of usability and integration that I had with the Onkyo. Not even close on that front... really doesn't like my Mac mini as a media input.. Onkyo fine! Keeps switching itself off despite changing all the settings... annoying for my Alexa input! It has an app which would be a good addition if it wasn't overly complex from a UI/UX perspective. I work in technology and run a software dev team so am no tech luddite but this thing has currently beaten me!! Had to RTFM far too quickly and downloaded the full instructions. Not impressed :-(

Rated 5 out of 5 by from Replacement for faulty Onkyo Bought to replace faulty Onkyo Reciever. Perfectly connects to existing 5.1 Kef egg speaker setup. Sound and vision superb.

Rated 5 out of 5 by from Great features at affordable price Meets all of my needs for a small living room 5.1 setup. Really happy with the look and feel of this amp.
Date published: 2022-01-13
Rated 4 out of 5 by from Powerful & intuitive but simple! Very pleased with this unit, simple setup with all necessary equipment provided to auto-setup. Unit is a powerful driver of speakers, noticeable difference from my 4 year old Yamaha unit. Good option of sound modes but Dolby is typical Dolby and a bit hit and miss for 5.1
Date published: 2022-01-11
Rated 4 out of 5 by from Fantastic AV receiver Great product from Denon for a mid-range speaker. Would recommend
Date published: 2022-01-10
Rated 4 out of 5 by from A good investment Bought to replace a 20yr old Sony for the convenience of Bluetooth and HDMI. In order to get the best out of this you have to stop it making any auto choices and set it up yourself ... especially around a good subwoofer. my only gripe is the lack of any digital spdif audio out... something the old Sony from 20 years ago had. It days 175 w / channel, but that is unlikely as a normal volume is around 60/65 and I suggest in a very large room it would struggle. However it is clear, clean and when setup accurate at 5.2 Dolby...it does require a self powered sub to perform properly. In the light of some stupid prices of old and deleted stock online due to chip shortages, it is an absolute bargain

Rated 5 out of 5 by from Superb AV receiver for the money I bought this just before Christmas for a home cinema system. It has some great features and the audio quality is great through some Monitor Audio speakers.

Rated 4 out of 5 by from Denon AVR S-660H Great AVR especially useful for 120hz Gaming. Make sure you update the unit straight away. Has more of a warm sound which I prefer.
Date published: 2022-01-03
Rated 5 out of 5 by from Great product and fast delivery. Our old dvd player died so we needed to replace our analogue amp to have hdmi throughput. This as a dedicated 5.1 amp is perfect. Not too many bells and whistles just good solid performance.
