Yo CanopuS! Such comparisons are not really useful. You give me a song, a perfectly good one, and a fine performance, and I can find 10 perfectly good mics that can make it sound like shit.
Also, I can show you some signal chains with gain stage problems that can make a Neumann U47 or a B.L.U.E. Bottle sound like Mr. Microphone.
Finished sound is the result of a combination of factors. This includes the performance and the sonic quality of the source, the material, the room, the instrument, the mic(s), mic placement. the cables, the mic preamp, compressor, gain staging, the recorder, FX, the mix, EQ. Then you reduce the resolution to an MP3, and finally the gear that the downloader plays it on, and you have guaranteed that *no one* can tell you diddly about the mic.
I'll guarantee you that if we take, say Paplo Casalls, playing a $150,000 cello with a $30,000 bow, and Al Schmitt mics him up in the A-room at Atlantic, using Mogami cables into D.W. Fearn, and then to a big time Pro Tools setup, or for that matter, a classic open reel, he can make it sound great with almost any microphone that has ever been made.
Conversely, if we take some drugged up ignorant homeboy mic'd up by his buddy Slush, in a tin roof garage, into a Behringer Eurodeck cranked up too high, into a Soundblaster, they can make a Soundelux or a Brauner sound like a Radio Shack mic.
Of course, I should point out that drugged up homeboy's new release, "Cutting the Bitch in a Tin Roof Garaj", will be critically aclaimed, and Slush will win a Grammy for best new producer.-Richie
