Audiophiles will be pleased with support for streaming files up to 24-bit/384kHz, as well as MQA and DSD256; but even if you eschew the wonders of Hi-Res Audio in favor of some simple Spotify streaming, you won’t be disappointed by the sound. Even beyond the flawless musical performance, LS50 Wireless II is a breeze to set up thanks to the KEF Connect app. It is intuitive to use with any source in your home, and it allows simple over-the-air firmware updates that bring you new and improved features with the minimum of fuss. The manner that this is integrated into the top of the cabinet is beautifully realised and it’s details like this that help the KEF to be genuinely user friendly. The fit and finish is every bit as good as the passive version too. Do be aware that there some unavoidable quirks of placement that the KEF can’t easily nullify though. Any HDMI or optical connection from a TV is going to have to come out to the master speaker and both of those speakers need mains power. If you can dress it correctly, a setup based around the Wireless II will look outstanding… but you’ll need to put the effort in. Solid all-rounder I'm using these in a smaller room as desktop speakers, and I wasn't sure if I would have enough space for a separate amplifier. In the end I decided on the all-in-one solution to save space.

Connecting the computer was a bit more work. I would have appreciated a USB input, but instead I needed to use an external sound card with a TOSLINK output. You could own these KEFs and have little need for the dedicated app, considering the LS50 Wireless II support AirPlay 2, Google Chromecast and Bluetooth, and are also Roon Ready. LS50 Wireless II is more than a high-performance loudspeaker; it’s the perfect all-in-one speaker system. It reveals every detail of your favourite music, which you stream from any source thanks to wireless compatibility with AirPlay 2, Chromecast and more. The obvious question is whether the KEF LSX II would have been a better solution, and I think they would have been a very good choice too, but the LS50W2 had a bit more clarity and depth to them. I did not want to compromise.Simon Davies led the KEF Industrial Design Team from 2000 through to 2018. He was responsible for key product designs including LS50 and LS50 Wireless, The Reference and R Series. Since 2018, Simon has acted as a design consultant for KEF, and continues to work very closely with the KEF Industrial Design Team. There are many wireless stereo speakers on the market, but ‘wireless’ doesn’t always mean what you might think. Just like its competitors, the LS50 Wireless II streams music wirelessly. It also goes one stage further, though, in featuring a wireless connection between the speakers themselves – no umbilical cord required. If you want to improve file resolution from 96 kHz/24 bit to 192 kHz/24 bit, then simply use the supplied interspeaker connection cable. The LS50 Wireless II sound incredibly well balanced, displaying great stereo separation and a wide enough soundstage to truly fill any room with detailed, clarified audio.

As I have been able to write a full and considered review of the passive LS50 Meta, in which I have had the space to go into the driver revisions in some depth, I will not repeat them here. Every improvement that has been made to the passive LS50 is replicated on the active one and they reflect KEF’s near fanatical attention to detail when it comes to the business of driver and cabinet behaviour. These sonic advancements are not only a credit to KEF's engineering but also representative of how far such speaker system concepts have come in recent years. Needless to say, we look forward to hearing more products using MAT technology in the future. As well as offering the dynamic range to make the most of Hi-Res music, the LS50 Wireless II also supports many associated formats. MQA (Master Quality Authenticated) – as used by TIDAL Masters – is compatible. ROON Endpoint status means it’s compatible with the award-winning music player – including Hi-Res files. In many ways, what was more surprising was how KEF had made the LS50 active. Rather than go the traditional way of applying amps to speakers; attach/integrate the amp and power supply and leave control to somebody else, via either RCA or XLR, KEF turned the LS50 into a system. It became a device that needed only an internet signal to be a fully functional device in its own right. As decisions go, it was a good one because KEF has sold a great many of them.As a product following in the footsteps of such a huge success, the KEF LS50 Wireless II arrive with a world of expectation on their shoulders – but they well and truly meet those expectations.
