This is off topic, so feel free not to respond, but I'm curious if people can
actually tell the difference between DIN and DINa. Its only a centimeter and a half difference in spacing on either side. How much of a difference can that really make in a big shitty room...
To the OP though, I am very happy with my 63s. I run them 9 times out 10, though thats mostly since its just between these and my CK 1X pair; which are cards made in 1989 and I think the 63s just sound better.
Sort of going along with my first question, but I honestly can't tell much of difference in "openness" between my cards and hypers. That said, I don't do any really critical listening, so I'm sure others will have stronger opinions one way or another. Also, anecdotally, and it might just be the brighter aspect of the mic, or possibly the gear chain? but when unscientifically compared to MK4 recordings I sometimes check out, my 63 recording will sound more 'spacious' than the Schoeps cards. Not quite as detailed and certainly with a different 'flavor' but more open none-the-less.
As for crowd noise reduction in the hyper pattern vs cards, I'm a cynic at heart, and like my stereo pattern choice question above, I have yet to hear any difference in crowd rejection between the choices. Sort of the like the "golden ear," people can say there is but in my personal experience I have not witnessed it. My tests mostly come from running my personal 63s vs. 1X, but also from comparing my 63s to friends MK4, and a little listening to friend's MK4 vs. 41 from shows I've been taping at as well. Acoustic differences are certainly there, but actual amount of background crowd noise I have found to be practically the same across the board.
And again, I'm not a knowledgable or scientific type of taper, so my first hand experience is pretty much based on gut feeling over proper conclusions, but I'm totally happy just running the 63 hyper caps for pretty much everything. 61 caps are certainly on the list, and I would love the option, but the hypers fit my personal needs just fine. YMMobviouslyV.
I will also just add that I ran the 63s very FOB for Panic this weekend and they sound freaking awesome....though I'm sure everyone's does from 7' high that close to the stage.
