late to the discussion, but still need to add my experience. Initially i was using an Eclipse, with a pair of 18’s and and 19. The 50’s were added later. Wireless connectivity was important to me, as I didn’t want cables running through the living room (or rather my wife didn’t). For me the WISA technical solution, worked fine, especially the 96 Khz / 24 bit sampling rate and the dedicated 5ghz standalone wireless connection.

For watching streamed video, the setup is now, unsurprisingly, 50’s providing Front left and right, the Eclipse, centre, the 18’s rear left and right, and the 19 the base. The sound quality is superb, the latency is excellent. No issues at all. Occasionally, i have to reboot the system, possibly once a month, but no more often. It is annoying when it happens, but certainly happens no more than any of the other kit i have in the house.

However, I wasn't convinced about the hi-fidelity streaming via the eclipse to the 50’s, and whether I was extracting the best quality available from the source (Deezer hifi and Tidal) . I was finding the Chromecast built-in on the eclipse particularly problematic. Consequently, started researching availability of WISA standard equipped pre-amp/DAC’s and came across the PRIMARE PRE35 PRISMA. It only has two channel WISA connectivity, but for Hi-fidelity listening from stereo sources, that is all i needed.

I have to select “Wireless powerlink” on the app, when using the PRIMARE which finds the speakers every time. I have to reselect select Auto when finished listening and wanting to use the TV. Then turn the TV off and on again so that the Eclipse finds the 50’s again, which is a little irritating. But it works every time.

i was so impressed with the sound quality, i decided to have a vinyl renaissance. Consequently, the set up now includes a Rega planar 3 with Exact cartridge / Rega NEO TT PSU and Rega Fono phono stage hard wired to the PRIMARE PRE35, connected to the 50’s via WISA link. I can hear every nuance, include audible differences from platter mat changes and sub platter upgrades. One major advantage of the WISA link is that that the turntable is the other side of the room to the speakers ensuring no interference from the potential bass output of the speakers on the turntable

I am sure there are hard core audiophiles having an apoplectic fit on the above, but WISA and the BEOLAB speakers, provided a fantastic neat solution.

Honest truth is i dont know. However, the source for them is a Rega Planar 3 / Rega Fono Mk3 phone stage to a PRIMARE PRE 35 Prisma, Pre-amp. I’m not really too interest n the speakers manipulating the signal, as long as what is converted from Analogue to digital (24 bit / 96 kHz) at the Pre-amp end is converted faithfully and without any loss at the BEOLAB 50 end. I have to say, the sound quality is astonishing. Sat listening to Crime of the Century this morning, right in the sweet spot, and was blown away.

I dont use the 19 or the 18’s when listening to Music.. Only the 50’s. As you suggested the 19, is sited at the back on my room to supplement the 18’s when watching Movies in 5.1 on the Eclipse. On its configuration it does make a difference. Admittedly, completely superfluous otherwise 

A couple of cents worth of opinion.

I have no idea why the BL50s seem to have this type of problem? However, some comments to chew on.

1. I believe wired source to these loudspeakers "should" be the best - especially as PL is analogue.

2. I keep my BL90s in wired and have no issues. Is this a BL50 and not a BL90 problem??

3. I can cite lots of problems with very well established products that have simple telegraphic issues:-

3a. Auralic suggest that you feed their Aries G2 Streamer wirelessly for best sound (digital, no interference) rather than by wire.

3b. I find it impossible to stream Qobuz, but can do amazon HD and tidal ok. Auralic say a very good Router/Modem is required for thier systems to work properly. Im not so sure.

3c. I often Bluetooth an Astell & Kern DAP to E8 earphones. Totally useless when moving. But then again - its the same with all earphones this way with the DAP

3d. When I stream Astell & Kern DAP to a stationary loudspeaker (Essence or Beoplay P2, P6, A6) it is perfect. Thus A&K are useless for BT transmission when moving (how useless is that?0

So maybe...just maybe this is a transmission code issue? Regardless, one could argue it should work.....but then the examples above show other high-end gear does not always work as expected. 

Go to wired connection on the BL50s. That should solve most of the issues.
