A turntable generates a special kind of a signal. It has to be modified to create another kind of signal. This modified type of a signal can be used by different kinds of audio equipment, like modern speakers, PCs, etc. In other words, a pre-amp just converts a signal that can be used by other devices.
This is not a complex process at all, the key point is to match the colors of cables. Usually, a stereo receiver for a turntable is a large device and there are many inputs on the back panel of it. It is necessary to make sure you matched the right cables. Of course, colors can help you, but that is not the only thing you need to keep in mind.
Some people prefer retro trends. With best speakers for vinyl and record players still available on the market, you can have a nostalgic music experience. When you go to a club, you’ll notice that DJs usually use turntables for their setup to produce music.
