Speaker Cables? why all the hype for expensive speaker wire?

After listening to many speaker cables, I am listening to basic 14 Gauge, high purity copper speaker wire and find myself shaking my head.  Does this basic speaker wire sound better than cables many times the price?  I am really starting to ponder that question.  I think I am hearing things on my records I never heard before and better balance of sound.  What are your thoughts?
