Definitely avoid the phantoms which will distort at high volume. Admitedly loud. People were Walking out of a demo when happening once. I do not think you will find anything better than the kef model speakers. They are consistently regarded as amongst the best for powered small actives with active crossover design. I reviewed the lsx on my site 13th note and I agree with what HiFi‘s view . I think the ls50w might be a bit too powerful for a desk with close listening, so you could be wasting money, lsx are more than gutsy enough, unless your desk is like a bond villains.
one issue with the lsx and LS50w speakers is the app is sometimes poor. My Lsx speakers kept falling out of the network using the app, whilst everything else didn’t. What HiFi mentioned this and people contacted me about it. So I’d maybe recommend adding a streamer like the Bluesound node 2i (which is terrific for the money) and use it into the digital input. You want to be aware sound is better if you tether them with Ethernet cable You get in the box which shouldn’t be an issue if you are desking them,
