I fully acknowledge all the different presentations various vinyl solutions provide, but I think you make a good point about digital and the early claims of “perfect sound forever”. That would have at least implied to me that at the very beginning various digital players would have sounded the same. They did not. And now years later, they still do not.
I think that early marketing pitch or claim or whatever it was, was quickly abandoned. Digital does, however, offer extreme convenience and search capabilities, and based on the products discussed in this thread, lots of opportunity to add many many boxes and cables and different presentations based on filtering choices in some.
