Though I am not a religious I have to agree with Mighty Sam McClain.
I have some very good recordings and my all time favorite is also my favorite test disk. It also contains superb musical tracks, machine gun, canon, jet flyover.....
Alan Parsons Project
It will test any system to the max in every way and the recording quality leaves nothing to be desired.
I have the original MFSL version which cost a lot when new and still quite valuable.
