Versatile and Modern
These things sound great and are exceptionally versatile. The high-end bump lends a presence to the sound of these mics that I find pleasing in many applications. The multi-pattern selectors, HPFs, and pads make these extremely handy in the studio.
The multi-pattern stereo pair allows you to execute mid-side, XY, 2-figure 8, and just about every other stereo technique you can imagine. For acoustic guitars the presence bump imparts a very forward, modern sound. In that way these mics are ideal for acoustic heavy singer-songwriters. A twin figure 8 setup allows for wonderfully isolated vocal/gtr performances. I have recorded many sources with these mics and find vocals, acoustic guitars, and drum overheads to be where they really shine.
I do mostly rock music and I am not a big fan of these mics on a distorted gtr cabinet . The presence boost often tweaks the ranges around 2-3kHZ in ways I find harsh...though for ambience mics you can do some really creative stuff with all the polar pattern options. Up close to the cab for cleaner signals these mics can pick up some really awesome tones, but for close in, high-gain applications I go back to the 57 or other dynamic workhorse mics.
For vocals these mics can add a sheen to most performances. For screamers a/o really breathy singers the presence boost can be a bit much...especially in productions where many vocal overdubs are to be used. It's nothing a little subtractive eq'ing can't help...but I prefer the mic to fit the sound source whenever possible.
All in all I think these mics are amazing so long as you choose the them for the right applications. 90% of good sound is a good performance in a good space. Mics, pres, and signal processing is that other 10% and with a pair of these and a pair of regular 414s you'd be hard pressed to find a source that you cannot capture beautifully and in variety of ways.
