@echoz - I have heard both the Ls5/5 and the Harbeth 40.3 and in my opinion the Harbeth's don't project as uniformly as well as the Ls5/5 doesalso I prefer my music a bit louder, while the ATC SCM50 SL handle more power I feel they are also better suited for orchestra and electronic music which is a bit more detail oriented.But we each have our own tastes, I have listened at great lengths to the ATC speakers and for me they check all of the boxes for my style of music and my system.
