Tube sound

Tube sound (or valve sound) is the sound produced by a vacuum tube-based audio amplifier.  All amplifiers distort to some degree; some audiophiles prefer the sound produced by tube amplifiers.  The reasons for the difference in sound between tube and solid state electronic devices is a continuing debate among audiophiles.
