Has anyone here heard and compared both?
Yep. I demo'd both of them a while ago as I had narrowed it down to these two when looking for a pair of active speakers. They were both on the end of a new Naim Uniti Atom and I spent a couple of hours at the dealers putting them through their paces.
In short, I bought the AE1's as (in my view) they were streets ahead of the Kefs in every single respect and I made that choice pretty quickly despite the dealer lauding the LS50's as the better speaker. 3 months in I have no regrets and think the AE1's are an absolute steal at their price point.
They are currently on the end of my Linn Akurate DSM and sound wonderful - these two are a great match.
