Onhwy61, there is more to it than that- due to the fact that vacuum tubes failed to go away when transistors came in decades ago, two different methods of amplifier and speaker design, test and measurement exist to accommodate either technology.
One of the results of this is that equipment matching has become fairly important, otherwise there can be tonal aberrations, despite the amplifier and speakers having otherwise flat response.
