The C451's have a tipped response curve (check the curve that AKG includes with them). Their response is very *level*, but there is perhaps a 4 dB rise between 20 and 20khz. You can hear it in them, as they tend to sound *very* bright. They're *very* good microphones, they just sound bigger (brighter?) than life. As a recording engineer, I like to use the 451 for acoustic guitar, and on mushy piano's (not your Steinway, I hope). The brightness helps emphasis the attack of the guitar, and gives the piano a brightness that is hard to obtain with an equalizer. On the negative side, this excess brightness might be part of what you call "digitalis". I suggest that you try a pair of the new B&K recording microphones (4004, 4006 i think) or the Neumann KM84 or KM83. The 84 is quite flat, and doesn't have the tipped response that the 451 does. They have a very neutral sound, sometimes almost warm. The 83 (omni) has an on-axis rise in its response. You can play with its positioning to use this rise to advantage, or run the mic at 90 degrees incidence to make it flat. Rick Chinn John Fluke Mfg.
