using microphone to break in arm/phono cable?

Vinyl Asylum

Welcome Licorice Pizza (LP) lovers! Setup guides and Vinyl FAQ.

I am getting a new phono cable in this week, and the manufacturer says I should not break it in with a high level source, since the cable is so thin, and that I should just break it in with a cartridge level source.
I was thinking I could use a microphone and break out it's XLR's, to bare wire, then to the cartridge leads ( 3 at a time, not 4) of my brand new Phantom, then connect the RCA end of my new phono cable to a mic preamp.
My phono cart is .5mv output, and it seems my Shure SM58 mics output reads:
Sensitivity (at 1,000 Hz Open Circuit Voltage)
â€“54.5 dBV/Pa (1.85 mV)
1 Pa = 94 dB SPL

So does this mean that the max the mic will put out is 1.85mv?
If so, that is not bad, only 4x what a cart puts out, and probably the mic will be putting out way less than max.
Any thoughts? I'd love to be able to put some break in time on the arm cable and phono cable while waiting for the turntable to be delivered in a few weeks.
