Meanwhile, the Denon DHT-S517 costs £379. Global pricing is yet to be announced, but that works out at about $500 / AU$700 - and as it comes with a subwoofer, you don't need to shell out extra to ensure your home cinema sound is bass-heavy.
Cheaper Dolby Atmos soundbars don't always come with the upfiring drivers you need for 'true' Atmos sound, relying on digital signal processing and pyschoacoustic techniques to trick your brain into thinking sound is coming at you from every angle.
However, the new Denon soundbar contains two upfiring drivers to bounce sound up to your ceiling and back down to your ears, making it feel as though you're in the heart of the action when you're watching films and TV shows.
Those upfiring drivers are part of a seven-driver array, comprising left/right channel tweeters, midrange drivers, and a dedicated center channel, which Denon says delivers "unmatched clarity, dynamics, and cinematic dimensionality".
If the Denon DHT-S517 sounds anything like its pricier predecessor, the DHT-S716H, you can expect a wide soundstage, balanced frequencies, and impressive volume levels - though this older model had a 3.0 speaker configuration and no Dolby Atmos support, so the listening experience will be a little different.
However, like the S716H, the new soundbar comes with a range of sound modes tailored for different listening situations, as well as a dialog enhancing feature that should make mumbling actors sound a bit clearer.
HDMI eARC, optical, and 4K UHD HDMI inputs mean the Denon DHT-S517 should work with pretty much any TV, while Bluetooth connectivity means you can use the soundbar to play music wirelessly from your smartphone.
Can Denon compete with the Sonos Arc?
While many Denon products come with support for the HEOS ecosystem, which lets you create a sound system with the need for lots of cables snaking around your home, the brand's latest soundbar doesn't have this feature.
Even though the DHT-S517 boasts many of the same features as the Sonos Arc (plus a wireless subwoofer thrown in), the lack of multiroom support could put off potential buyers.
All Sonos speakers work within the company's wider ecosystem, so buying the Sonos Arc - or the cheaper Sonos Beam (Gen 2) if you're not bothered about having upfiring drivers - makes sense if you already have the brand's devices at home and want to create a no-fuss hi-fi setup you can add to and take away from as you please.
Which soundbar you go for really depends on what you want from your home cinema setup. If you're looking for a relatively budget-friendly option that still gets you Dolby Atmos sound, the Denon DHT-S517 could be the answer - but, if it's unrivaled connectivity you crave, Sonos soundbars still come out on top for us.
