Would I be wasting my money to get a turntable?

I am thinking about getting a turntable but I have a Class D amplifier (Nad M33) which digitizes all the analog inputs. If the amplifier is just digitizing the source is there going to be any difference between the vinyl and just listening to lossless digital streaming sources? Is there any benefit to me, given my current amplifier with has no analog pass through capability, to adding a turntable to my system?
