David, all,

I partly disagree in this hate campaign against 3,5 mm and plug in power.

Since I started running plug in power a few years ago, I never have
problems with mini-jacks, unless worn out gold plated contacts on head phon=
es.

The by far most common problem in my workshop are cables which have
broke where the XLR housing ends.

Long ago, buying gears with XLR's meant buying quality. Vice versa,
stuff with mini jacks were made for the poor ones and bad.
That is not the case anymore. Mini jack gears might be really good
and XLR stuff might be bad.
Today there is no reason to feel "amateurish" because you use mini-jacks.

I have two Zoom H4n and the XLR inputs are broken on both of them.
(3,5 mm works)

There are small closed bags that you can buy anywhere to clean your
eye glasses. They work fine to clean connectors too.

Klas.
