The Preamp: The Command Center of your Stereo System which has a major influence on how your system sounds. Preamp select which audio source to listen to and provide you with useful features like tone controls. Most stereo preamps have fewer features than surround-sound processors, placing more emphasis on sound quality and analog audio performance. Audiophile preamps have both balanced and unbalanced analog inputs. If your power amps have balanced inputs, you will get the most benefit by choosing a preamp with balanced outputs. Others also include one or more digital inputs, and still others also feature a phono input (a special type of input that accepts the direct input from a turntable for playing vinyl albums).
