Pet audiophile peeves - name yours

I'm still keen on the "hot stamper" seller here.

I am particularly amused with his listing for Steve Windwood's "Back in the High Life." He is asking $75 and has the chutzpah to show the "$5.99" price tag on the shrink wrap in his listing picture. That thing is so hot you'll need to grab it with oven mitts.

The only thing more pathetic then the seller in question is the poor guys who believe and pay him.

1) CDs (or songs on CDs) recorded in inverted phase.
2) non-standard "pin-2: hot" XLR inputs &/or outputs on components.
3) different worldwide a/c polarity.
4) manufacturers who charge an arm & leg to change component voltage.
5) components that are mostly air/hollow inside.
