 (Note that vinyl records may be mastered differently from their digital versions. ) In the amplification stage , Amplifiers A preamplifier selects among several audio inputs, amplifies source-level signals (such as those from a turntable), and allows the listener to adjust the sound with volume and tone controls. Many audiophile-oriented preamplifiers lack tone controls. A power amplifier takes the "line-level" audio signal from the preamplifier and drives the loudspeakers. An integrated amplifier combines the functions of power amplification with input switching and volume and tone control. Both pre/power combinations and integrated amplifiers are widely used by audiophiles. vacuum-tube electronics remain popular, despite most other applications having since abandoned tubesfor solid state amplifiers.
