The other question would be, how critical is the preamp to the kick?
It's hard to say what is "critical", since there are so many factors that influence the sound:
drummer's technique
sound of the kick
room acoustics
close mic choice
close mic placement
overheads and room mic (choices and placement)
mic preamps
compressors
recording media
I'm probably leaving out something.
In theory they're all critical, but if you had to nail EVERY single one of those factors in order to get a good drum sound, there would only be about 3 good sounding recordings of drums each year.
So yeah, all those things help. In answer to your question, having a Neve or API for your kick sure might be an improvement over your Mackie, but so would having a forty foot long room with 25 foot ceilings, or using a pair of Coles ribbons as overheads. The trick is not use lack of any of the above listed factors as an excuse for getting a crappy drum sound. It's our challenge as engineers to get decent sounds in less than optimal situations. In some ways, that challenge forces us to become better engineers, and is part of the fun of being in the business. Overcoming of obstacles can be its own reward!
Remember that Greek philosopher (I forget who...) who said give me a long enough lever and a place to set a fulcrum and i can move the earth... Well, give us an SM-57 and a minidisk and we should be able to figure out a way to make a great recording...
