Buddy of mine has this also. It just tests your imaging, clarityness, etc of your speakers. There's even a Terminator sound somewhere that we're all familiar with.I ordered it the day I posted the pic. Other than saying it is brand new and is the "IASCA Official Sound Quality Reference Disc" it doesn't give me dates.

I know, I was watching a 5 Star Car Stereo video and one of the guys in the video is a judge in the IASCA SQ part of things and he actually uses this disc to judge cars. Of course his is a 2019 disc and I have no idea what year mine is but the tracks he was listing off were the same or similar. The new disc even has illustrations on the sound staging of where instruments are and should be heard coming from. I hope mine does too.Buddy of mine has this also.
