Don - if you get a guitar made by an Archangel I would expect it to sound heavenly. But as you say there are many beautiful instruments. I think it's a case of America being so big that there are so many good instruments made there that there is no incentive for people to look outside that continent. There are some amazing instruments being made in Europe and there are many in the far east working their hearts out producing beautiful instruments getting no recognition because they are "Pacific Rim". Racist? I would say so. America's Pacific Rim from here.
No country has a monopoly on good instuments and certainly no one maker has.
