Most overrated audio manufacturers?

Any time I read and advertisement or read about a product that starts with the word" Reference" I know it is bull%$##@

What about if the word Reference is something other than the first? Is it still BS, or is it credible?

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.

Plasmatech your more focused question would make for an excellent thread!

Its an interresting question, but how do you define over-promise and under-deliver? If you're talking about sound quality, for example, its subjective. I don't see how you can define something like that unless you rate things on an individual basis.
