I have purchased the 2015 Ultra Pak Plus...and the 2016 upgrade after.

However I was told that I should have bought the Audiophile version from a friend as the quality of the tracks are better.

Can someone confirm this for me, and what is the bitrate or quality difference?

I am noticing some tracks have a bit of a odd sound like a gloss or and overtone that happens when playing them. Not all but some, and I am playing the song at a very close to or exactly on the suggested tempo.
