A: Because it breaks up the logical flow of conversation.
Q: Why is top posting bad?

If there's a fault, randomly pulling bits out and replacing them isn't
going to find it.  Quite a lot of people have said that the VZ-10M mix
out is quieter than the individual outs - maybe it's supposed to be that
way.  In which case, you've ripped out a bunch of capacitors because of
some silly superstition and replaced them, and quite possibly introduced
a bunch of new faults into the bargain.  Don't do that.

The other alternative is to examine the mix output circuit and see if it
actually *is* working correctly.  If it isn't, fix it and see if you
like the higher level output.  If it is, see if you can modify it to
give you a higher level (most likely by altering the feedback resistor
around an opamp for more gain).
