I use a little free program to look at the frequencies in high rez files. It is a quick way to look at how much content there really is above 20 KHz. It says nothing about how it will sound, but it interesting to look at the data.
Spek Frequency Analyzer
I started using it because there is sometimes question as to whether the files on HDtracks are really high rez or not. Some downloads have a lot of content above 20 KHz, others almost none.
