Welcome to the world of vinyl! Some of us old farts had no choice… way back when. But starting by learning what you have is a great idea. So spend time with it, understanding the sound.
Once you really know what your system sounds like… well, you have a world of better sound ahead of you.
After fifty years using turntables, my recommendation is to have a carefully chosen phono stage of no less than the cost of your turntable. Until I bought a Audio Research PH8 my phono-stage always held back my turntable. I would highly recommend a used one for your system… or better. Audio Research is a true audiophile companies and makes world class phono stages.
Raving reviews of inexpensive phono-stages are great, but never compete with true audiophile phono-stages.
