Only other thing I will point out is that LS50 design for the coaxial tweeter mean they have some level of a waveguide to narrow the directivity and reduce sidewall and floor/ceiling reflections. The S40 would almost definitely be a wider dispersion, so depending on how you set them up and how far away you are, you’re likely getting more reflections from the frequencies covered by tweeter on the S40.

I had a brand new pair at home demo just a couple days ago. Got pretty mixed feelings about them - silky/delicate sounding treble, but midrange is just off somehow. Bass was excellent - taut and snappy. (Amp: AVM C9)

Thank you all. just posted some details here: https://www.superbestaudiofriends.org/index.php?threads/the-two-channel-advice-thread.3191/page-38#post-310428
