Why Switches Influence The Sound Quality

I’d rather get a stick in the eye than have to listen to this Hans guy. I can't help but wonder if he isn't deliberately annoying.

He doesn't have to be deliberate to annoy you.

@cleeds :

I understand what you are saying. But please understand English is not his first language, and he is a bit old. 

hans is extremely knowledgeable, and in my view quite worth making the effort to listen to - he has a real depth of experience and tries to share it, even if his delivery is not the most user friendly

"a bit old."

Suitable for framing.
