The U.S., England, Germany, Italy, France, Japan, and China all make bona fide high-end audio gear. Korea? I've heard some South Korean gear over the years, but I can't say any of it made a strong impression.
I recently stumbled upon Metal Sound Design's Web site, and while I can't guess what their speakers sound like, they all have a great sense of style and appear to be well-built. The South Korean company has won numerous awards and prizes over the years.
True to their name, the company's speakers are made out of metal, and I love the look.
