All digital recordings deal only with finite numbers such as number of samples, start finish... i.e. all digital recordings have a "Floor" and a "Ceiling" meaning that nothing goes either bellow or above audiable freequencies in digital recording/reproduction. In analogue reproduction nothing is finite. Analogue record can contain even 5Hz or upto 42Khz of unaudiable information that will basically signify the image of original sound source and define the original tembre or "colour" of the sound.
If I'm speaking in front of you, you can clearly hear where the sound is comming from and you can literally difine the tembre of my voice because not only audiable freequencies are presend in audio signals. The same way it could be heard from the analogue record. There are even sounds that still nearly impossible to record with digital recorder such as bird songs in the forest.
To say for the conlcusion you can upgrade your digital setup untill you hit the "Floor" and/or the "Ceiling", but you can infinitely upgrade your analogue and maybe(certainly with proper speakers and room) you'll rich whatever record can deliver.
