And it becomes a lot more significant difference once you venture into manipulating the audio. Even the built-in "Tone" adjustment will definitely give you a very noticeable difference (in favour of the uncompressed, of course), if not but because, by definition, the compressed files have already been 'manipulated'.
And taking an upgrade deal (as opposed to buying like it's a 1st time purchase) is actually not all that pricy...but of course 'pricy' is very much a relative term.


Just because you can, doesn't mean you should!
