      Yep, agree with much of this review. Bought mine direct from KEF on day they were released (before any reviews) and loved them ever since.

      I have mine connected to my gaming PC via 3.5mm, my PS4Pro via optical & for music use Spotify Premium (via Spotify Connect then just controlled via Spotify phone app. Phone app can even turn them on & control volume).

      Have not needed to use the KEF Apps at all unless I want to stream some music off my NAS (rare). I do use cabled connection between speakers (not tried them wireless). Also have my connected via ethernet to network. If you ignore the App concerns (I rarely need to use Apps) they are a 10/10 from me.

      I've also used as a Roon endpoint with Tidal with no issues at all, even MQA Masters.

      Best speakers of this size I've ever owned.

      My setup

      Hi Psikey, they look tiny, what size monitors are they in your piccie? They don't suffer not being on dedicated stands then? I was thinking I might just put them on my TV cabinet. Is there a sub you'd recommend, as I'm new to these types of speakers. I'm looking to replace my Q acoustics M4 soundbar which has been good, would these be markedly better? Cheers, Phil.

      Ed, you might want to consider changing your reasoning here, as it doesn't make sense:
      TIDAL's online server supplies its MQA supporting client devices with MQA masters tracks at their standard undecoded/distribution resolution of either 24/44.1kHz or 24/48kHz, so should be streamable wirelessly by the LSX. It's one of MQA's MSPs that the MQA client device decodes the MQA file tracks, so saving on the amount of data being streamed over the internet!

      Great review Ed. :smashin: I do love the idea of these speakers.

      I’ve been investigating them, and can’t find a definitive answer as to whether the sub out has a bypass function for the LSX drivers?

      Anyone have any better info’?

      Seems not alas

      Quite a good usability review from John Darko here, he already has the LS50 Wireless to compare.

      KEF's LSX is a more affordable hi-fi...


      Short version: most of the good stuff of the LS50 W for a bit less. Audio performance is excellent, although more suited to smaller room/desktop/soundbar-replacement duties than as a true hi-fi replacement.

      I was originally going for LS50W but too big for the room. The LSX may look small but they are mighty.

      I just have mine on yoga blocks and sound sublime.

      I dont feel I need a woofer as base is great already. If I was using with my big TV in main lounge I'd likely be going for the KEF Kube 8b.

      Both 27" monitors. One a 1440p Asus Rog Swift 165Hz G-sync, the other a 4K HDR.

      If I understand your question correctly, if you connect a suitable sub the LSX offloads base to the sub and uses the LSX for mid & treble. Option in KEF app for adding external sub.

      Hi Ed,
      Enjoyed the review, just wondering as you also reviewed the SVS prime wireless speakers, which £400 less, how close are they in terms of performance to the Kef’s.

      I’m currently running Q acoustics BT-3 with a Rel t-zero hence looking at upgrade options, the speakers will be positioned very close to the back wall on stands.

      Thanks

      It doesn't matter how good they sound, If the app is not very good with these speakers, then it spoils the whole usability function, an app is very important to access your music.

      Personally don't agree with this in respect to the LSX at least how i've been using them. I used the app for 5 minutes during the initial setup and not touched it since.
