There are way more options available today than ever before when it comes to audio gear. For most modern audiophiles, the term “preamp” implies to analog stereo preamplifier. Even though certain modern preamps have one or more digital inputs, while many are equipped with a variety of features, a component with only digital inputs is usually called a DAC, and one that has HDMI inputs and supports surround sound and home theater is generally referred to as a processor or pre/pro.
A typical stereo preamp tends to have a several sets of analog audio inputs. While a few modern preamps do a lot more things, the prime purpose of a preamp is simply to let you select which input to listen to, control the volume, and subsequently pass that signal on to your power amp. It does all of these tasks while making sure that the sound quality is not compromised in any way. The role of the preamplifier typically involves adding some gain to the input line signal and then passing it on to the power amp. In certain ways, a high quality preamp is considered to be the control center of a stereo sound system. To find the perfect preamp for your system, you need to think about the features that you actually need. There is no point in getting a device that is too complicated and actually comprises the sound quality.
