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.

Every once in a while I crank out one of my test records/cd's.  And yes, more often not I make a tiny adjustment to my system -- either a slight toe-in or speaker-width adjustment or a minor twist of the dial on my sub-woofer.  In any case, my Stereophile test CDs are just fine.  Sure, they never come close to giving me the fidelity some of my favorite CDs and LPs, but they certainly do more than simply take up space in the CD rack.  My favorite test CD?  Probably the one I got with my now long-gone Denon CD player.
