General Audio / Re: Test files needed
Last post by file627 -I don't have CD-CHECK (tm).
But, honestly, most of the ones that came out after ~1988 are worthless for techs.
For example, that Philips Audio Signals Disc 1 – SBC 429 , has a whopping 99 tracks. This and other Philips test CDs were put out by one of the formats' developers. It comes right out of the R&D dept. Not sure Sony put out their own suite other than YEDS (which is on Archive). Denon may have, as one you noted above:

One critical, must-have track, as was often reported on in Measurements section of reviews, of Stereo Review, Audio and even Stereophile (for a while), was/is/remains the SQUARE WAVE test.
It's importance (in audio) is controversial, to say the least. But it is very weird and interesting how folks go out of their way to discredit it -- especially when it comes to is application in digital audio:
