24/96 versus 1644 files with more different kinds of musical samples:

There are 4 different selections, the first 3 are musical and the last is the usual keys jangling
You can use the ABX plug in in FOOBAR2K to restrict your listeninig to any part of any of them, so a minimum of 4 different tests are possible.
There is a ultrasonic IM test at the end after the short little audible test tone. Make sure that you can't hear the difference between the 44 and 96 KHz versions with it. You may have to turn your listening level down a few dB to obtain the desired totally silent results.
If these work out, I hope to base a number of other tests on the same basic 24/96 test file.
