The thing about mics is that no matter where you try and research them online there are good comments and bad comments on the same mics.
I remember one day spending a few hours online and reading comment after positive comment on just about any mike I decided to look at. Looking at freq. responses can be helpful if you know where your particular voice has an edge. "gold sputtered 1" diaphram" seems pretty common and something I would look for.Noise circuitry is so negligable as to not be noticed in a mix usually.The "low noise" they talk about isn't discernable in many cases. The Neuman actually added tube noise. My first condenser years ago was an AKG C3000B. I still have that mic. People love to hate it but it fits with certain material. I think it has a mylar diaphram,almost indestructable for a condenser. I started singing with an SM57, a close cousin to the 58. I am a tenor and the 58 is a great mic for that. I sing though one of those every week and it really does work well for my vocs.Lots of albums were made singing on a 58.
My staple dynamic now is the EV ND767 taylored for male vocal.I highly recommend this mic both live and for recording. I picked up an MXL 990 at a GC grand opening for 49.00,actually used a pair of them for a concert recording. A nice recording mic with a silky smooth characteristic. Nothing seems pronounced,only a 3/4" dianphram I think. In a pinch I use it. I am thinking about a higher end MXL,or Rode NT1 . I am only a hobbiest weekend player, I might reconsider if I were recording someone else.
The Rode Nt1 is one of those mics that I regularly read about in magazines. It is usually one of these, " We used a Rode NT1,AKG,Neuman,AT" and usually includes a really decent mic pre in there somewhere. I seldom read of anyone using something like an MXL. If they did they don't want that getting out.
Most of those low end condenser mics are made in China now no matter whos name is on it in that price range with a few exceptions....that's not a bad thing but like a very vanilla feeling I get looking at all of it. One is so similar to another that I start to ask what the difference really is.
Bub hit the nail on the head here on mic pres, a decent pre can certainly help the sound. I think the truth is probably somewhere in the middle, The really high end mics are probably overkill and some of the mid MXL or similar mics sound much better than the high end guys want you to know.
