NoFo, to be more accurate, they should have said:
"a Ribbon Mic for every PREAMP".
Before these new mics, the Royer ribbons (like all ribbon mics until now) did not require phantom power. But as a trade off, the signal from the mic was very low compared to most phantom powered condensers. On many preamps, to get a strong level going to tape/disk, you had to crank the preamp so loud that you could hear the hiss and grunge from the preamp's circuitry. One way of dealing with this lately is using one of the many preamps that have variable resistance settings at the input stage.
The VIPRE and Avalon 2022 are good examples of preamps with this feature. (One of the Meeks has it too, I believe, and the new Universal Audio pre as well).
The new phantom powered Royer outputs a far more robust signal, making this problem moot. (At a somewhat higher price, though, than the original).
So, yeah... it's not necessarily the mic I can buy with change from my food stamps, but at least i wouldn't need to go out and get a special preamp as well!
Oh, yeah... one more thing. If you really are considering a ribbon mic, remember they are in general the most fragile of the various types. You don't want anyone blowing into them or smacking them around. Although i do believe Royer has a very generous lifetime ribbon replacement warranty.
