First I had hs80m, because of the power and the bass, but then I checked out hs 50's next to it when my girlfriend bought those for her living room (she wants clean bright sound) and they totally blow the hs80's away when it comes to clarity and detail in the mid and high section.
So I sold the hs 80's and bought hs50's too, with alesis m1 mkII passive for the lows.
Now I again have good sound, which I like to compare with the genelec 8040's I had before them.
Test it yourself.
hs50's are more like the ns10's when set the mid + hi on + 2 trim, not the hs 80's.
