So, where do horn makers obtain the metal for their horns? What type of specs go into an order? I have always believed that the metal in Olds horns are possibly responsible for their sound. Kanstul has semi-copies of a number of famous horns, but while the Kanstul horns are great, there is still a difference between them and the originals. Not worse, just different. There are a number of manufacturers that attempt to clone the strad. Never has exactly the same sound. I know there are hundreds of factors that determine sound, but the metal is something that is rarely talked about. Maybe Ivan will give us his take on this topic.
