Are the Stereophile setup CD’s any good?


I saw a few on EBAY and I know they made at least 3-4 different ones. Is one better than another for speaker placement?  

Thanks in advance.

For info on a test that eliminates many of the variables, with regards to finding out whether your system is correctly reproducing what's on your media, read this article:     https://www.stereophile.com/features/772/index.html      The LEDR is now available online, as a download, if you're a streamer:    https://www.audiocheck.net/audiotests_ledr.php            And, the Chesky CD's still offered:      https://www.amazon.com/Chesky-Records-Sampler-Audiophile-Compact/dp/B000003GF3     
@curiousjim,

Sent you 3 CD's a little while ago.  Stereophile Test CD 1 and 2.  Chesky system evaluation CD.  Expect them Saturday via Priority mail.  Sent you a PM with all info.  Enjoy them.
Thanks Rodman,

I’ll read everything this evening when I have a bit more time.
