I've put up a Black Crowes mk21>kc5>cmc6xt>722 recording from the Thomas Wolfe in Asheville and recently, a mk41>kc5>cmc6xt>722 Dinosaur Jr. recording from the Variety (
http://bt.etree.org/details.php?id=16079 seeds are still around).
The Black Crowes recording was a little heavy on the low end, but I don't want to lay blame on the 722... the stand was never raised above 5' and was pretty far back in the auditorium to be running subcards. I think if we'd have been a little closer, things may have turned out a bit nicer, but nonetheless, its a nice recording and is entirely listenable.
I'm in love with the Dinosaur Jr. recording, though. Its not quite as detailed as the V3, but as I've mentioned before, I think its a nice match with the mk41s. Great imaging in that recording. J.'s guitar will flatten you can hear Murph and Lou beside J., respectively, laying it down. I can close put myself right back in the venue and hear them onstage. Check it out if you're really interested in hearing the Schoeps>722 combo. I think it speaks for itself.
One reason you don't see so many straight 722 recordings is that others, me included, haven't completely jumped ship from our older units, plus, its fun to play around with other options... this IS supposed to be fun, right? Sometimes we forget!
