I've had variable results with the internals. Just excellent on a couple of quiet shows, I found absolutely nothing wrong with them, including just great bass and crystal clear highs. One very loud show was pretty nice, too. Then a couple later, one where I had a very poor club sound system and the recording sounded as good as what I was hearing, then a couple of very loud shows with nearly overwhelming volume. These were just so/so. I think my dpa's would have done somewhat better on the last 2, but otherwise, I'm pretty impressed with the internals/ ymmv/
conclusion here, so far-----quiet shows, absolutely use the internals, fucking great results.
louder shows, maybe, maybe not, good sound system will probably do pretty well.....
