Why valves?

In audio applications valves continue to be highly desirable. Valve amplifiers behave differently from transistor amplifiers and produce different tonal qualities. Some people like the elegant designs and the glow made by the tubes, but more importantly valve amplifiers produce a warmer, more natural sound.

There are many theoretical reasons why valve amplifiers may sound better, especially biased in class A, which is the most linear class of operation and produces only about 1/100,000 parts (minus 50dB) distortion.

Most importantly it is personal choice.
