Tostados, I guess I am deprived. I live in Houston, and amplification is usually used to augment the sound; invariably used in large venues where the big names tend to play. It's not intrusive, but they certainly don't use tube amps, and it's not quite the same as all acoustic. The local guitar society gets a few players to come play in a Unitarian chapel where you can sit close enough to get only direct acoustic sound; heard Barrueco that way, a real treat. I think even Segovia and Parkening, when playing Jones Hall (where the symphony performs, it's fairly large), had some sound reinforcement. Neither ever used a modern, loud guitar, afaik.
PTSS, thanks for the responses. You may be right, I had not thought of it in those terms. Volume, especially fortissimo passages, has always been the problem with classical guitar, which is unsurpassed at the other end of the spectrum. "Stonger" guitars are made now with double tops (with a nomex core) or elaborate bracing systems and a very thin top, all intended to produce more volume. But most players would say that it's a trade-off and that such guitars do not have quite the same delicacy of tone and balance that more traditional designs may have.
