The way I conceptualize it is that 100% would be the best sound you could possibly hear without any improvement. Most audiophile stuff I consider to be in the 85-98% range of the best possible sound. Depending on what kind of person you are getting to the low 90% range may be just perfect for you, but some people hear huge differences when you spend lots of money to get the extra percentages. So if the IEM set up he has was at a 92% he would now feel that his new set up is at a 94%. 2% closer to that perfect sound. However it is all subjective as I could make my setup exactly the same and I could feel like the cable only adds a .5% change. It is also depends on how much that percentage is important to each individual person. For example I heard a $400 Pro-ject carbon at an audio store which is around a 90% for me, but then I also heard a $15k turntable which I felt was probably around the 97% of the best sound in the turntable world. The 7% may be minute for some (especially considering the price), but that 7% was night and day for me.
I guess I see it as trying to add a scale to convey how much closer you are getting to what you consider the perfect sound. Of course there is no clear answer as all audio is subjective.
