Something like a Denon DRA900H might work for you. It has HDMI ARC, 4 HDMI inputs, RCA inputs, and others. If you can get a second hand DRA800H I’m sure that’ll be fine for you too.

No worries. The LS50s are great so, whichever amp you decide on, will provide a great listening experience.
It should drive them just fine. I don’t worry about wattage too much when I’m discussing with customers. I’ll demo a 100W amp vs the AXA35 and, generally, the Cambridge will give a much better sound. I sold some Kef R11 Metas yesterday which were powered by a Cambridge EVO150 and they match sonically very well.
Cambridge Audio pairs nicely with Kef. I’m in Canada so am not sure the price in Euros but the AXA35 is a good little amp. I work in home audio so have the AXA35 hooked up to a CXNV2 which sound good through the LS50Metas.
I sell speakers for my job and will always recommend Kef but, as others have said, it’s best to listen to speakers and see which you prefer. Audio is very personal so you should buy speakers you like listening to. A good in-between Kef and Klipsch would be something like the Polk ES15.
