Parasound Classic 2100 Stereo Preamp

Preamplifiers are really only required if you choose to buy a stand alone amplifier. Integrated receivers like the popular Onkyo A-9050 have an amplifier and preamp bundled together in one component.

Preamplifiers are designed to let you easily switch between music input sources. This allows you to have more than one device connected to an amplifier at a time. 

A preamp will also take the lower powered signal from analog and digital audio devices like CD players,  record players or even computers and boost the voltage before it hits the amplifier in your system.

While some amplifiers are capable of amplifying these lower line level powered signals, many require a preamplifier to amplify the signal first before it reaches the amplifier.

Preamplifiers are easily distinguished most of the time by a large volume and smaller bass/treble tone controls. Generally an amplifier will not have these button or knobs unless it is integrated with a preamplifier and sometimes also a radio receiver.

Many preamps built today will also include a built in Digital Audio Convertor or (DAC). While DACs can also be bought as separate components to add to an existing system. Many new preamps and integrated amplifiers now also come with a high quality DAC already built in. This let's you easily hook an iPod, computer or other digital music source directly to it as it to convert the digital music to an analog source for your speakers to play.

Premp/Amplifier Vs an Integrated Amplifier/Receiver

While this may not always be the case. Separate audio components generally provide a higher quality sound than integrated all in one devices.

It allows for better signal isolation for less chance of interference and distortion if the devices are housed in separate cases. It also offers a little more flexibility when setting up your system.

For instance, some experts feel a high quality preamplifier has more of an impact on the quality of your system than an amplifier. By purchasing your components separately, you can choose a higher quality preamplifier and spend a little less on your amplifier.

It will also allow you to upgrade to a better preamp or amplifier at a later date without needing to buy both devices.
