I think perhaps many spend too much money and time chasing new types of audio playback sources. Especially people without unlimited resources.
Perhaps the best approach is buying the best playback device one can afford, sticking with it, and spending your money improving the rest of your system.
That is exactly what I did. I have always stuck with Redbook CD, and have built my system around getting the best sound quality from it. I am glad that I have followed that route. If I would have spread my money into other sources, like a server for 'hi rez' digital (as if CD were not extremely high resolution...) or vinyl, I would have the stellar sound quality that I have now from *none* of all the sources.
As just an example, I would have not have had the money to buy my new Octave HP 700 preamp, which turned out to become an essential backbone for the sound quality of the system.
