Most overrated audio manufacturers?

This type of thread only invites "cheap shots" by those with various motives and experiences we are not fully aware. Thus, those who indulge this type of pseudoinformation may diss some very credible manufacturers.

Quicksilver? Really? Mike Sanders has been making superb gear for years and obsessed with quality and affordability. And no, I don't work for him. Like any manufacturer, his gear may not be a perfect fit in your system. So, do some research.

I would have preferred a more focused question of which manufacturers over-promise and under-deliver, and cite at least two instances of this occuring.
