With all due respect, "You always get what you pay for" sometimes includes the perceived "goodwill" of a name brand. For example, Sennheiser U87's-oops I mean Neumann U87ai's

are way overpriced IMHO for what you get nowadays.
I think Electro-Voice was very clever back when they designed a "regular" DYNAMIC microphone to sound just like a ribbon when they created the EV 666. It won't be as sexy of a buzzword as saying ribbon, but it's a heck of a lot more practical for many home and broadcasting applications IMHO. The EV 666 did boot out the the RCA 77 out of many radio and TV stations so they were successful as planned with it-enough to make so many the original die wore out! I've torture tested mine (high vocal SPL), and it works like champ.

P.S. If you get interested in the EV 666,
let me know via PM as there are some
fine points to getting a "good" one.
