A preamplifier (preamp) is an electronic device that takes a low-level signal from a source, such as a turntable or CD player, and amplifies it to a line level that can be fed into the power amplifier. You need a preamp if you're using separate components for your home audio system.
There are several types, including tube preamps, solid-state preamps, passive preamps, and active preamps. Factors such as sound quality, price range, power consumption, and features should guide your choice.
You can use this page to compare the prices of various preamps available at multiple online stores. Make sure to consider additional costs such as shipping and taxes.
Consider the number of inputs, output impedance, gain control, tone controls, phono stage, and compatibility with your specific audio components.
It depends on the store's policy. Some stores may offer in-store demos, while others might not. In most cases, you can read reviews from other customers or consult the product specifications to make an informed decision.
A phono preamplifier (phono stage) is a specific type of preamp designed for turntables that use a phonograph record as their source. You need a phono preamp if you're using a turntable in your home audio system.
A passive preamp is essentially just a volume control, while an active preamp includes additional features such as tone controls or a built-in phono stage.
Some well-known brands include Pro-Ject, Marantz, Schiit Audio, Lehmann Audio, and Rega.
Some high-end preamps come with an external power supply to improve the sound quality. However, many entry-level and midrange preamps do not require an external power supply.
Consult your individual component manuals for specific connection instructions. Generally, you'll want to connect your source (such as a turntable or CD player) to the preamp, and then connect the preamp to your power amplifier using RCA cables.
