What does Flat Earth mean in audio circles?

Some folks who make very good audio equipment may still be flat earthers -- although very sophisticated ones. I've read of a highly regarded speaker manufacturer who doesn't believe speaker cables make a difference (can't remember which one). I'm not familiar enough with the owners of Linn or Naim to answer that specific question though.

For most practical purposes, the earth is flat.

Flat Earth is also the name of a distributor of European brand audio equpment like Mana, etc.

I thought they were being somewhat ironic and it had something to do with records being flat.
