I have to say using bluetooth with these speakers is not the best way to take advantage of their sound quality.
I use Roon with iTunes, Tidal, and Flac files to directly play to the Kef's. Sounds great and I get a very nice interface. That won't help with Spotify though and I agree the app is still pretty bad. It was unusable for months after the speakers came out.
according to their specs, the sample rate of the USB in is 2x higher than the optical, which is why i started by connecting my laptop via USB for music. That, plus the AppleTV 4 doesn’t have optical out, I haven’t bothered to use the optical. i know that i get a good phantom center from the RCA. I can’t say how well optical works.

i could use the usb out when watching from my laptop, but i’m usually using the AppleTV, so i just run it all through the same cables for ease of use. i stopped using a wired connection for music, again for convenience. i’m not a bluetooth fan, but it’s nice to be playing music wirelessly. i move around, and take the music source with me so i can change the playlist or volume.

incidentally, i use bluetooth with the muo for the opposite reason. i started with a wired connection, but use bluetooth more now so i can leave my phone connected to a charger, and carry the speaker around with me.

Looks like the LS50 Wireless might have some new competition.

I haven't found any official articles or specs, but I just saw this posted on the Secrets of Home Theater and High Fidelity Instagram account:



"Elac powered bookshelf speakers" is all that it says. Apparently it's called the "ELAC Argo B51 Bookshelf Speaker" with 250Watts of amplification built-in to each speaker.



I've been following the Elac forums a little bit and I was anticipating an active Uni-Fi UB5 to be released at CES. It looks like that's what this is although it's definitely dressed up a little bit. It will be interesting to see some specs and pricing information.

Main System: Vizio P70 4K TV. Selah Vigore Speakers. KEF Q100 Rear L/R, Mirage BPS 400 LFE Sub. (2x)Rythmik FM8 Subs. Denon AVR-X4500H Receiver. Lyngdorf TDAI-3400 Integrated (2 channel). Oppo BDP-103. Zappiti Mini 4K HDR. GIK 242 Panels, Tri Traps, Monster Bass Trap. Various Vicoustic Desktop: Dynaudio BM6A mkII. Paradigm SUB10 w/ PBK. Cambridge DACMagic+ DAC. GIK 242 Panels, Monster Bass Trap Master Bedroom: Vizio M55 4K HDR. BG Radia In-Wall/Ceiling Speakers (5.2.2). NAD T758v3 Receiver

These have been talked about for at least a year. There was a rumor they were canceled. Found this;

Only a little less than the Kefs and I've seen the Kefs for around this price instead of $2200 retail.

Interesting. Based on the price : performance value of their uni-fi series, I would have thought these would be more in the $1,500 range.

That’s what people projected but either it was unrealistic or Elac couldn’t pull it off. I’m interested to know what inputs it has. The Kefs retail for $2200 but since they have been out a year you can get then for around 2K.

Looks like it's meant to be used with an outboard DAC. No usb or digital inputs.

Not of interest to me then. But it does say you can use the ELAC Discovery Connect wireless transmitter for wireless whatever that is.
Also looks like not available until May/June.

Just read this quote on the LS50W in a CES show report...

"The LS50 Wireless were streaming high resolution audio (24/192) over a wireless connection using Roon and I wouldn’t have known that they were wireless unless someone told me."

So how do you make that work with these speakers? Do you simply connect the speakers to your wifi network and then Roon will "notice" them and allow you to use as a source output?

Roon will see them as a Roon endpoint.

Got it. Makes sense. So if you're streaming Tidal through Roon and using the LS50W's as the end point, you'll be listening to Tidal HiFi (assuming you have that option). Correct?

If you're using a MAC running Roon and use the LS50w as an endpoint, can you stream right over your existing wifi network, or do you need something special with a MAC, like an Airport Express? Thought I read somewhere that was/is the case.

Also, will the LS50w's be able to be updated to MQA via firmware at some point, or is that not an option with these?

You use your existing network and set the Kef speakers to wifi. Works great. I'm listening to it right now :-) You cannot beat the Roon/Kef combination.
I don't know about native MQA in the speakers but alot of people have asked for it. Not sure if Kef can manage that.
But Roon should have it fairly soon from what I have read.

Got it. Thanks for the reply. So if Roon incorporates MQA, it will stream to the LS50w's and play accordingly?

I’m not sure about how MQA via Roon would work with the Kefs since the Kefs have their own DAC. It would have to work through the Roon integration so I imagine it could work.

Not sure if this goes here. I guess this is the official LS50W thread.

What are you guys using for multiple analog sources?  I’m using a Rogue Sphinx amp as it has an incredible phono stage and have my turntable and SACD player (analog) going into it. Have used my Dragonfly Red DAC via usb and Roon for MQA as well, but prefer using the usb input on the LS50W with an ifi purifier 2. Have thought about using a vintage Marantz or Yamaha receiver with preouts as their phono stages are very good and I love the vintage vu meters. I hide my Rogue in my cabinet.

You are using a turntable with the Kefs? I’ve been thinking about doing that.

Does anyone know if they will support Apple Airplay 2 which is out later this year? It is supposed to be a software update which iis why so many wi-fi speakers are expected to have support for it.

In the UK the LS50 WIRELESS are £1999.

Unlikely. They have had a lot of complaints about it to the point it is in their FAQ. They claim its for Apple Music which of course Airplay works with all streaming services.

Ok so LS50 WIRELESS do not support AirPlay, but KEF X300A do.

That's correct. I don't know how they are currently but I have read a lot of complaints about the stability of the X300A. Those of us who are early LS50W owners will be familiar with this but I think they have finally gotten the LS50W's to be reliable after being out for a year.
It will be interesting too see if the X300A gets Airplay 2. I don't think much of Kef's ability to write software and I'll bet they use cheap offshore development resources.
For computer speakers I would buy the Vanatoo 1's instead which are half the price but sound great. They don't have Airplay but do have a USB port.

Easy workaround is to buy an Apple TV 3rd generation for ~$50 off eBay and use that instead.
I agree with SoCalCyclist, KEF is probably not thinking much about stuff on the Software side of things -

Most likely Kef is being cheap and using contract offshore development resources. It's pretty obvious on quality alone but some fo the read me's were clearly written by people whose primary language isn't English.

Thank you. I am based in the UK and called the headoffice today, talked to an Engineer.
They might consider adding Airplay 2 as it is expected to be software based.

Anyway that is not a blocker for me. I can easily connect my iMac via optical/usb or iPad via RCA connection directly.

White looks amazing with matching white stands and a nice white turn table.

I have the KEF LS50W that replaced my Audioengine HD6 as computer speakers. It's plugged in using the optical in. I noticed that occasionally the left speaker would cut out for a second or so. Has anyone else experienced this? It didn't happen with any of the previous speakers I had and my setup remained the same except the LS50W. One possible explanation is that I am using a longer Cat-6 cable than the one provided.

Only one way to find out - through deduction:

1. Put back the original Cat cable shipped from KEF. Does the behavior occur?
2. Buy another cable of the same length as the one that you're using, does the behavior happen?

I have already tried with different cables and the same result. The KEF cable is too short for me so I'd need to redo my whole setup to use the originals. It happens very infrequently, like once every couple of hours. I suppose I could do this for a day and see what happens.

If it is due to cable length, that would be disappointing as that limits where these speakers can be placed. I'll report back after I have time to rearrange things.

I doubt it would be cable length - it could be a product issue (not surprised) so hopefully you're within a year of warranty. As with most new generation of products, they have production issues. LS50W has been riddled with issues - my first one arrived and the left speaker was giving out a burnt metallic smell every time I turned it on. Sent it back to Amazon for a replacement (wasn't light!).
