I have been using the DPA 2006C stereo kit for several years now; I was told I got the first pair that went to a non-professional customer. At the time I bought them, I was thinking of them as a stepping stone towards the 4006s, however, I think they sound so good that the next capsules I buy will either be 4015s or 4011s. The compact bodies are very small; I think they are stealthable if you are so inclined. For open taping they are preferable to the active cables, in my opinion, as you can use them with any XLR cables you want and any standard mounting hardware. There is a recent Matisyahu recording I did with them on the LMA (there are a few others there, too, maybe a moe. and a Gov't Mule), if you are interested in rock in a large club type of situations. Some MMW and a Wood Brothers still active on etree. Maybe a Calexico on Dime. If you prefer jazz, let me know, as I can provide samples of a number of bands that let me record but not share (The Bad Plus, a bunch of times, Omer Avital, Bill Carrothers, etc.).
I also have the 4060s, and I think they sound great, but they are a little noisier than the 2006s and half as sensitive. In comparison, the 4060s are more truly omni and have slightly better bass extension; these differences might seem at first blush to make the 4060s better, however, for the type of recording I do, I find the 2006s have a bit better stereo feel to them and a bit less thump. Of course, there are tons of 4060 recordings out there, but I have samples of them too, if you need some...
