Tubes Rule! Really?

A day before the ides of March, Steven Stone asks the rather basic question – why are tubes better than solid state?


A good percentage of the audiophiles reading the statement,
“Tubes Rule!” will probably agree with it. My question to them is simple – why?

I ask the question because I wonder if there are more
insightful answers than the standard, “Tubes sound better.” We all get that
tubes distortion characteristics are more “musical” with fewer and reduced odd
order harmonics. But what audio designer in their right mind would knowingly
create an audio component that drives a tube (or solid state device) into
distortion? The exception, of course, is with guitar amps, where it’s all about
perfecting and controlling overdriven sonic characteristics.

But back to the question of why or why not tubes rule; aren’t
tubes merely a part in a circuit design? The phrase, “It’s the driver, not the
car” comes to mind. I think that today’s A-list audio designers and their best
designs aren’t about a particular part, but a synergy of parts. And depending
on which parts a designer is most familiar with, that’s probably what they’ll
use in their current and future designs.

I maintain that one of the reasons we see so many tube-based
audio products is because tubes have been and continue to be readily available
components. Most standard tubes have been available, pretty much without
interruption, for over fifty years. Literally millions of audio engineers have
experimented with, and thousands have built, components based on tube gain
stages. Because tubes have been such a constant and reliably available part, many
fine designers have chosen to use them, become familiar with them, and based
their designs around them. Cool. But, does that make tubes rule?
