RE: What would happen if I upped the uf value of an audio path capacitor

Assuming both caps are equivalent construction and material quality DA, esr, esl seems to go up with package/capacitance value size in a given voltage, temp range and tolerance, though I'm sure there are probably plenty of exceptions to that rule. I'm thinking the differences due to the above will be mostly negligible.

However.

This configuration is a passive single pole high pass filter. It may indeed have a real affect on system performance depending on your situation.

There will be about a fifth of a decade difference between the rolloff frequencies, at equivalent loading, with the 100uF cap obviously having the lower rolloff frequency. The rolloff frequency heavily depends on loading. More loading give higher 3dB frequency.

If your load is a high impedance pre amp input for example the differences in the audible band are very negligible however if your load happens to be something like 8 ohms speakers you'll ruin the sound entirely....no more bass.

To be fair the 47uF ca; would already be ruining the bass if that's what you are doing so I'll guess your load is higher impedance?/?
