Interesting thread. I moved from standmounts to towers, but there are standmounts that I still thought were uniquely special -- Fritz Heiler's Carbon 7 Mk 2 SE, to be precise.
That leads me to one reason to prefer a standmount -- it’s made with special talent and attention and there is no equivalently good tower in the line or perhaps just none at all.
It’s like that one particular menu item at a restaurant that is exceptional -- but not a main course.
Or that short song that is just a "gem." (Think: "Blue, Red, and Grey" by the Who. Short, perfect, unique.)
Question for anyone interested in commenting: Name a standmount speaker which was special even though a tower from that same maker/line was not. I’ll start:
Dynaudio Evoke 10 and 20 sounded special to me. Dynaudio 30, the Tower, was "meh."
