Mic capsules in parallel vs series

[Mephitus]

I am trying to build a studio mic from a few electret/condenser capsules I have salvaged from some old commercial grade telephony equipment commonly used in call centers. I have seen some conflicting reports on wiring multiple modules either in series or parallel (usually parallel) to aide with noise reduction as it increases the total capacitance of the circuit and attenuates the signal a bit. I was hoping that someone might be able to help clarify this a bit and if this is even a good idea. If it helps, I will be using it with the pretty classic LM353 pre-amp circuit.

I do not know why the datasheet for the old LM353 dual opamp does not mention distortion. Also it has some noise that you do not want in a mic preamp.

A newer OPA134 single or OPA2134 dial audio opamp has extremely low distortion and noise.

A noise reduction mic is not two or more mics. instead it is one mic with a port at the rear so that distant sounds that are far away are cancelled.

Part of noise reduction strategy is tightly involved with phase cancellation - which will also give a few headaches if you're simply summing multiple mic inserts.
I'm sure there are better brains here than mine, but you may google
mic summing amplifiers, possibly adding phase and/or noise cancellation.

I am using a LM353 as I am trying to work with what parts I already have or can salvage from other equipment on hand. (Divorce is sucking me dry) But I will double-check my stockpile to see if I have anything that might work a bit better. Total distortion levels don't need to fit any kind of production quality requirements. Mostly this is for learning and partly for improving the output compared to bare electret modules connected directly into the mic input of my computer. I found a few reference designs for summing and differential amplifiers specifically for electret mic noise reduction (Linking below). I will breadboard them out and play around to see what I get. If I learn anything particularly interesting I will post an update. Thanks for the help!
