Denon AVR-X4000 Features
The X4000 comes with a host of next-generation lifestyle features clearly geared towards making the receiver easy to integrate into a modern networked home. Whilst there's no WiFi or Bluetooth, the Denon can be connected to your home network using a standard Ethernet cable, making streaming audio and internet radio simplicity itself. It is also DLNA 1.5 compliant, allowing for content to be easily streamed and you can of course hardwire your iDevice into the receiver’s USB inputs and control music playback via the remote. In terms of file support the X4000 is fairly comprehensive, providing DLNA streaming and playback for formats such as MP3, AAC, WMA and FLAC and WAV up to 24-bit/192kHz.
This enhanced network capability includes the addition of support for Last.fm, Flickr and Spotify. The addition of Spotify is particularly useful because it means you have access to a vast amount of music, as well as certain aspects of your account like pre-saved playlists and any music you've "starred". As you might imagine, you can't access your imported music this way, but since the X4000 can connect with your home network via DLNA, you can also listen to your own music collection. In addition to the built-in FM tuner, there is a full suite of internet radio stations, which means access to literally thousands of global channels and if you find any good ones, you can save them to your favourites.
Denon AVR-X4000 Video Processing
When it came to handling standard and high definition content, the Denon delivered an impressive performance, deinterlacing 480i, 576i and 1080i signals and scaling up to 1080p over HDMI. It also passed through 1080p/24 signals from Blu-rays without any problems and passed a 3D signal without any problems as well. We were pleased to see that the X4000 also had no problems detecting both 3:2 and 2:2 cadences, as well as scaling standard definition content without introducing unwanted artefacts or jaggies. As long as you left the picture adjust controls in their default zero or off positions, then the X4000 could pass-through the video signal without tampering with the image accuracy.
Denon AVR-X4000 Sound Quality
The bass was suitably effective too, with plenty of low end presence, although it could could have been better integrated within the rest of the audio. There was a tendency for the low-end to dominate rather than subtly add impact and in a bass-heavy movie like Pacific Rim, the result was a feeling of excessive low frequency effects, sometimes swamping dialogue on the centre channel. This could be mitigated to a degree but the overriding impression was of an AV receiver that was enthusiastic rather than refined. Of course that kind of enthusiasm, combined with plenty of detail to the soundstage is great for movies. When it came to music, the X4000 was still a capable performer but it sounded a bit clinical, thus lacking in the warmth and musicality found on other receivers. It thus suited electronic music better than lush orchestrations or acoustic recordings in some respects, although rock music definitely benefit from the enthusiastic delivery making it a good match for the Denon. Overall though we found the X4000 to be a good all-rounder and at its current price, you really can't go wrong.
- Detailed and lively sound
- Plenty of bass
- Easy to setup
- Attractive design
- Good connectivity
- Can sound a bit clinical
- Bass could be better integrated
Denon AVR-X4000 AV Receiver Review
The X4000 can be connected to your home network via Ethernet, making streaming audio and internet radio easily accessible. The Denon also includes support for AirPlay, Spotify and numerous file formats including high resolution audio, along with some handy video processing features. The X4000 has seven channels of built-in amplification and with support for Dolby Pro Logic IIz, DTS Neo:X and Audyssey DSX, it can offer either height or width channels. The overall sound quality was excellent, with a detailed, lively and enjoyable surround experience that had plenty of bass presence. The sound could be a little clinical, especially with music, and the bass wasn't as well integrated as we'd like. However, overall the Denon AVR-X4000 is an impressive performer and, considering its current price, it's also a real bargain.
