My feeling is that those terms are mutually exclusive... i.e., nothing "insanely expensive" is worth every penny! You're lucky if you even get a perceived value of 50 percent when it comes to super-expensive gear.
On the other hand, I have a lot of gear that is incredibly inexpensive that I think is worth at least twice its MSRP in terms of performance per dollar.
I mean who cares how good something sounds if you have to pay over $50k for it? No matter how much you pay, you can't change the basic laws of physics. But as soon as some prescient company offers a unit that can do exactly that... well, that would be worth pretty much any price...
