A good turntable is highly adjustable, easy to setup, sounds great out of the box, and even has modern necessities such as built-in USB port, which is useful in digitizing your LP collection. Good turntables are also speed accurate, but you shoudl always verify the turntables makers' claim about the advertised audible speeds.
Modern recordings are biased to be as loud as possible (young people like their music to be louder) and thus digital recordings are losing their edge in case of having a dynamic range. How can there be generous dynamic sound range when all music is so loud? Enter the good old turntable, which will play LPs recorded befroe the advent of digital recordings in all their rich dynamic sound range.
Moreover, old vinyl is also cheap.
FYI: Just google ' how to set up a turntable correctly' and you will find useful Youtube guides.
