Awards & Reviews

  • What Hi-Fi? Awards 2017
    Denon has gone to great pains to ensure anyone buying its £2300 AV receiver isn’t left wanting when it comes to the latest film and music playback technologies. But extensive features aside, what really impresses us is how articulate, rhythmically precise and musical this AV receiver sounds. It’s punchy enough and fully exciting, but we love how it gives importance to the subtler aspects of sound quality. A terrific performer, this Denon AVR-X6400H would be a worthy addition to virtually anyone's home cinema room.

  • AV Tech Media Awards 2017
    “Denon’s 11-channel receiver is a feature-rich, one box solution to running a full 7.1.4 home cinema, even adding Auro3D format support to the expected Dolby Atmos/DTS:X roster. Sound performance, polished via Audyssey’s top-line MultEQ XT32 calibration system, exhibits power, speed, detail and nuance, and although the AVR-X6400H’s extensive connectivity (including three 4K HDR-capable HDMI outputs and eight inputs) caters for complex setups, day-to-day operation is fuss-free. Integration with HEOS hardware opens up multiroom possibilities. It’s a class act.”

  • BEST BUY AWARD
    “Denon’s latest offers unrivalled features and Auro-3D out of the box, and delivers immersive, hyper-realistic sound. A cracker.”
