great sound quality, poor computer connectivityI've been getting to know my new speakers. These are going to replace my x300a's that I've used since they came out as my computer speakers. I work from home & my use is essentially split between listening to music, watching youtube videos and video conferencing.
The lack of USB connectivity has been vexing, I can connect via AirPlay, but the lag is a big problem for video conferencing. Also, volume and mute keyboard controls work most of the time, but not all of the time. The other issue is I am on VPN a decent share of the day - I think there is a way to poke holes for AirPlay, but it is a project.
I've been looking at USB-SPDIF converters as a potential solution. I don't like that I wouldn't have volume control, but I'm expecting it to solve the latency issue. There are a range of devices that do this job - wondering still if I'm missing something obvious. I contacted KEF support for advice and total crickets for 3 days now.
My only other gripe with the speakers is the annoying strum noise they make when they power on (annoying, but fine) and when they power off!!! Like, when its 2am and I am headed to bed. I turn off the speakers and in response they play a sound? I am turning it off... I clearly don't want sound to come out.
Nice upgradeI owned the original LS50W and sold them to upgrade to the new version. The good news is they sound better and the app is better. The streaming options and performance from the app is significantly better than the original version. The improvement in the sound is is a nice refinement in clarity, detail and effortless presentation. As good as the original is, the new version offers a worthwhile improvement. The not so good news is that the LS50II is not Roon Certified. The inability to use the LS50WII with Roon is a disappointment and a step down in convenience from the original version. KEF tells us this situation will be fixed "soon". BTW. Roon is available via AirPlay or Chromecast but this is not how I listen to Roon. Fortunately KEF did improve their app so while I am waiting for Roon I am able to easily access my streaming services. Again, great sound and a good app but please get the Roon Certification issues worked out.
AwesomeThese sound great but more important kef finally made an app that actually works.
