I didn't know about their roller-coaster-quality... thanks.
Here is what I don't like about the Vento 9s that the OP is asking about: (just my dingy-stuck-in-da-mud opinion)

So... lets start at how they look. I don't like the modern sleek-plastic-like look. I don't know what the cabs are made out of, but at 25lbs for the pair, it can't be much. My Ergos are about 30lbs each, and cherry veneer.
Specs claim 25hz on the low side... Hmm, I doubt it. I'm a tube guy and the 87db isn't likeable from my perspective... but I know my Ergos aren't efficient either...
I haven't heard them, and I haven't held them, so this is a very limited opinion. 1600 bucks can buy a lot of speaker.
Don't let my myopic opinions sway you though... if you've heard them and love them, then that's all you need.
