... From this example it should now be evident that the result of adding feedback increases the loop gain, which in turn decreases the output impedance of the amplifier circuit! We can then connect almost any load to the output, as long as the maximum output current rating of the op-amp is not exceeded. ...

Tube sound
Tube sound (or valve sound) is the characteristic sound associated with a vacuum tube-based audio amplifier. After introduction of solid state amplifiers, tube sound appeared as the logical complement of transistor sound, which had some negative connotations due to crossover distortion of early transistor amplifiers. The audible significance of tube amplification on audio signals is a subject of continuing debate among audio enthusiasts.Many electric guitar, electric bass, and keyboard players in several genres also prefer the sound of tube instrument amplifiers or preamplifiers.
