Digital LP’s

I've read on this forum a few times of people who after having spent tens of thousands on both their digital and analog rigs assert that they now sound the same.

Not being able to discern the difference between an apple and an orange seems to be a bit of a tragedy.

It makes me wonder if they would notice any difference after changing their cartridge out for another cartridge type. 

Digital recording to vinyl has been around longer than you might think.

I think differences that people perceive are more related to a specific master or mix and that digital in the chain is transparent. Analog to analog is like a photocopy of a photocopy with a similar result.
