I think the issue is for most people they have not heard a high quality audio file through decent speakers/headphones.
The soundcard is usually working as a processor and amp rather than just a source point. A standalone processor or DAC will add character or in some cases help clean up a signal before ideally hitting an amp which will allow you to drive the speaker properly. (And yes some amps will impart a character to music)
Most people have a sound card and passive speakers, some will use a CD player like me which adds a bit of power and acts a bit like a processor adding bass, mid, treble or weighting the sound left to right etc.
Basically to get the "best" out of a track you need to have all the bits in place, good source, good processing, good amp and good outputs. If ones poor then it lets the whole thing down.
If i played Ella Fitzgerald and Louis Armstrong's Summertime in 128bit MP3 then again in CD format you will hear differences, more in the fact the violins carry longer notes but also the general depth of the track. You can improve some aspects on lower quality sound playing with time alignment but your basically polishing a turd.
I think the best way to show someone the difference is to have them listen to both and ask them to listen for a specific thing, Louis breathing just before he sings, if all the bits come together to make a track sound great you can hear absurd amounts of detail.
Ill happily admit what I have in the house is pants an EK07 and some basic AKGs or Toslink to a Pinoneer unit and some slightly underpowered Roth Oli10, but thats because although I like good quality audio I dont have the space or time to set it up. When i move its on my list of things to do!
