Do pure copper banana plugs make a difference in the quality of the speaker sound.

I wonder if they have done significant blind testing?

I would also be curious to know if I were blind tested to compare speaker cables if I would hear a significant difference? I doubt someone would sit down to listen to a system and say this sounds like you are using Tera Labs or Kimber Cable. I do think buying a decent set of cables does make sense, but not spending more than $1,000. However, $1,000 is a lot of money. The system should I guess cost at least $10,000 to warrant the expense.
