mic ohm impedence

[nasher]

is it the higher the impedence the better the mic?

not necessarily.
the higher the impedance, the shorter the cable you'll need to get an accurate signal through...
a lot of mics have similar versions in high and low imp. for the same cost...or a switch
you can also get an external converter roughly 15 USD...but not sure i'd trust them.

peace,
