: Should I connect my MXL 990 condenser mics to preamps providing 12V or 48V of phantom power?

I recently purchased a pair of MXL 990 capacitor mics, as well as an Audiotrak MAYA 1010 audio interface. The MAYA provides 12V of phantom power, and I also have a small mixer with two channels of 48V phantom. The MXL 990 info sheet specifically states:
IMPORTANT - This unit requires phantom power at 48 volts, +/- 4 volts.
I can, of course, steer on the safe side and just use the mixer's preamps, but I know I'm going to use more mics/inputs for a project soon and the MAYA's preamps will come in very handy.
So what I would like to know is: does it matter which preamp I use? More specifically, is there any influence of the phantom voltage on the signal quality or is it merely a matter of "it works or it doesn't"?
