over the years, i have owned pairs of DPA 4011s, 4006s, 4061s, schoeps CMC64s, neumann km184s, km140s, AKG C460s, C480s, gefell m300s, AT4051s, and many others. there are really a lot of very nice mics out there that can do a fine job if you understand the situations in which they excel or have weaknesses.
for lower cost, i think the DPA 4061s are simply amazing, and i still use them as flanks. the AT4051s are just great mics all around, and compete with almost anything made, IMO, and you can get them cheap. i really have not ever found any mics at lower price points that have satisfied me like these two pairs. another extremely nice low cost omni is the AT4022 - i could not get over how great those things sounded for the price.
mid-level cost, the km184s and AKG c460/480 seem to rule here for me. the neumanns are about as musical as any mic i have ever used. the C480/ck61 mics are just about interchangeable with my DPA 4011s in overdub sessions - big transparent and honest - they are just great mics. the ck62 omni caps with the 460 or 480 bodies, and the at4049 seem to be my favorite mid priced omnis, though the dpa 4061s hold their own with anything (other than some self noise issues in rare situations).
higher cost - for me, the DPA 4011 is the most accurate and transparent cardioid mic made. the schoeps CMC64s were a very nice ORTF pair, but i found them a tad boomy for my taste as spot mics in the studio - i eventually sold those (but, hey - that's just me - i know many folks love them for good reason). my current main cardioid mics for ORTF pair are the neumann km140, which i just love - while they are not as flat as the schoeps, and not as accurate as the dpa 4011s, they have a sound that i just cant get out of anything else. for higher end omnis, the km131 near field, and the schoep cmc6/mk2 near fields are my favorites, with the dpa 4006s right there with them.
BTW, i did a shoot out of the km184 vs km140 over in the gear shootout forum on gearslutz if you are interested in hearing those two pairs side by side - i did the test on a flute and piano duo in the studio, to keep it clean and open to best illustrate freq response comparison.
