@OP If you don't already have a large record collection the answer is absolutely not. It's not just a question of whether the TT will be as good as your existing streaming system but also the opportunity coast. For what you will spend on the analogue playback you can make a substantial upgrade to your existing system.
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?
