Klipsch R-15M plus amp or Klipsch R-15PM

I have been searching for a replacement for my desktop speakers (currently Alesis M1active) for a while now and since I can't seem to be able to buy the Micca or Swan recommendations in Germany and the JBLs don't visually appeal to me very much I now lean towards trying the Klipsch R-15M.

I have been using the powered Alesis speakers connected to a Focusrite audio interface until now, which means I would have to buy a small amp to power these or buy the R-15PM (including the additional BT playback and whatnot). Do you have any advice on either choice (also which small amp to add, SMSL?) or any other speaker recommendations?

Thanks!
