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 4 out of 5 by from Lots of power and great sound I originally bought this as a compromise, the Marantz NR1510 that I originally wanted was too deep for my cabinet! Thought this would pale in comparison a little. How wrong could I be? This Denon unit has loads of powers and the sound is awesome. This has all of the features that I need in a reasonably priced package. Set up was a breeze thanks to the Audacy microphone included. Picture quality through the HDMI eARC is also brilliant, love the fact that it’s ready for 8k when I am. Having a phono stage is a bonus for when I buy a turntable. It plays nicely with my existing HEOS speakers. Would have been nice to have a bi amp/bi wire capability. Not sure how significant a difference in sound would be from an amplifier costing twice as much.

Rated 5 out of 5 by from It is so easy to set up. I purchased this receiver, as my long time favourite Sony 810 had died. I have been in the Sony ecosystem for the past 20 years, so changing was very difficult for me. After looking round at various receivers, I chanced upon the Denon. This was going to be a very difficult choice to make. I had read a couple of reviews where it had been said that it was difficult to set up ( it is not ! ) and one had said that the sound was lacking bass frequencies ( It doesn't ). I thought that I would take a chance as I had heard that Denon audio was actually quite good ( It is ! ). Setting the system up does take about 20-30 minutes using the equipment provided. Just follow the on screen instructions. I use the toslink system for my audio and the Denon took this in its stride, easily sorting out the return audio from my tv with ease. There is even a button on the handset. I am very glad that I chose to go for Denon and not the latest Sony offering, as I feel that Denon definitely has more to offer in comparable price ranges than the competitors. If you want a great sounding home cinema receiver, then you should choose the Denon over other makes, as what you will get is a far superior system.

Rated 5 out of 5 by from Amazing sound quality and looks great Just recently bought the AV receiver due to my last system dying but it was a worth while upgrade as the quality of the sound is so much better that I can't belive the difference. Setup was fairly easy and it is definitly worth doing the mic setup, wince done the surround sound really let's you hear every little detail in the movies

Rated 5 out of 5 by from Good overall sound I have had this av amp for a while now and I like it You get a setup mike to help you the information on the tv screen is useful even if it looks like the graphics come from an old Amstrad computer Also quite a large remote. But all in all a good looking good sounding amp And of course Richer sounds are great I won’t go anywhere else for tv and hifi

Rated 5 out of 5 by from Everything I was looking for I am very happy with the product. It offers everything I wanted from an AV receiver. A huge improvement on the Marantz I owned previously. The setup was easy and the quality of the sound is breathtaking.

Rated 5 out of 5 by from Great customer service! The team replaced a previous other brand unit that hadn't an ethernet port. Sent out the Denon asap without any issues and picked up the old one...great customer service!
