This page is intended to demonstrate the incredible value of our 6 Year Supercare. Under recent legislation, we are obliged to point out that you obviously do not need to purchase an extended warranty at the same time you purchase your electrical goods and are entitled to shop around. We have been encouraging our customers to do just that for years because, not only are our prices significantly cheaper than our competitors, but just look at what else we include:
Free loan machine (only if taken back to store)
Should you encounter a problem, just ask and you'll be provided with a unit to ensure you're not without music whilst your equipment is being fixed.
Like for like machine if unit is unrepairable
If, for any reason, we are unable to repair your unit, we'll replace it. Naturally, models do change so, while we can't guarantee that it will be the same model, we do guarantee that it will have equivalent specifications.
Free routine service / Maintenance checks
have your unit serviced as often as you wish, free of charge, during the 6 year period. (Normally excluded from extended guarantees).
45 day cooling off period
If you're not happy with our 6 Year Supercare package just ask for a full refund - no questions asked. After 45 days, providing no claim has been made, you can also terminate the agreement and receive a pro-rata refund.
If you use the policy in the 6 years, you'll have saved yourself tens and perhaps hundreds of pounds. If you don't use it...IT WON'T COST YOU A THING!*
* Simply return your unused Supercare policy within one month of the expiration date, and we'll refund the price of your warranty. Terms and Conditions

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 – adjust the volume, skip to the next track and switch inputs simply by asking Alexa or Google. 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.
