Songs for Speaker Placement

I managed to place them at a good spot... it's been a year and finally found the right spot where all music plays well.

Finally got the bass managed well... moving out from the front walls tame the boominess, reducing speaker distance apart increases mid bass.

Thanks all for the hints. 

This is a helpful diagnostic tool:  https://www.audiocheck.net/audiotests_ledr.php  The LEDR test is also available on some system set-up CDs, but-  the phase anomalies, present in some CDPs, can affect the results, as explained in this Stereophile article:     https://www.stereophile.com/features/772/index.html

@audionoobie, At least this is what I experience too. I am also experimenting a lot here... 

PS Audio founder Paul McGowan explains midbass in his youtube video titled "Optimal distance Between loudspeakers". I also find different listening distance from speakers affects bass as well. Bass null zones as they call it. You can hear more about it in a Youtube video by Dynaudio titled "A Master class in speaker placement" 1:56 distance to the wall.

Hope this helps.

'Depth of Image' by Opus 3 is IMHO the best recording I've ever heard in reproducing depth of image. It is on LP or CD and may be hard to find now. But I have heard it on a modest system carefully set up and it was so holographic as to be almost spooky. I used it for years setting up my own systems. The hard part was, having heard it perfectly executed, finding excuses for not getting my system to perform as well. :-)_
