I recently attended masterclass with former principle trumpets for TSO and O'Keefe Center. They were talking about how silly it is that modern trumpet players think a symphonic sound comes from a big mouthpiece. They all played something equivalent to a Bach 7C or 5C. That is the 2 cents from guys 80 years old or so who made their bones log ago in symphonies. Bud Herseth started out on a 7C until he got injured. So, what are we to take away other than as always, it is the player.
