Joseph,
Perhaps you did not receive our reply to your concern of defect.
"They are not defective. The metal nub that is mounted in the glass is magnetic. I assume you contacted the manufacturer as we make no claims for these capacitors"
What did the manufacturer say?
Remember, all the good reports, and great reviews of these caps are with the same construction.
I know for a fact, you will not hear "any smearing or distortion". Of course, all caps require burn-in.
