Not seeing the sound

Yes, the musicians are positioned in the correct places, and vocals come out dead center. So, I don't think the speakers are out of phase. I believe I may have found an audiophile unicorn.

I call this "not hearing the speakers"

Meaning, when you can no longer hear that you have distinct boxes making sound but instead perceive the illusion of sound events coming from a number of places.

Good speaker placement and acoustics matter a lot to make this happen.

When you see the phrase "disappearing act" or "the speakers disappeared", this is what they mean. You hear the music, however, if you close your eyes you don't hear the music coming directly out of the speakers. This is a key audiophile attribute IMHO. If your speakers sound good tonally, have frequency response that is high and low enough for your taste and they also disappear, you've officially got yourself an audiophile system!

Enjoy it........

The sound is quite 3D now. There's width, height and depth, if that makes any sense. Truly, a remarkable thing to experience in my own listening room.

Yup, that’s it. As stated above, the speakers have disappeared.
You should also now hear quite a difference between many digitally remastered (compressed) recordings and the original versions. The original will have depth and space between instruments, e.g., the singer will be forward and center, while the drum kit will be located at the back of the soundstage.

When I achieved this desired quality in my system, I stopped buying compressed remasters and went looking for the original CD's. This applies mainly to Rock and I now shop for music on Discogs.
