I doubt with the Walkman at hand, it was particularly difficult to get superior alien tech to build that hifi.
The tape and walkman are easy to repair/replace/upgrade. But the content of that second tape is something that's irreplaceable, since it was personal and chosen by his mom, who had since died. He didn't know what was on that tape either until the end of the movie. You could make a 31st century tape for Quill but it's meaningless if you don't know what songs to put on it or the emotional attachment he assigns to them.
I have no idea what any of that has to do with my response.
