Is soundstage DEPTH a myth?

     Once again: 

      The LEDR test I mentioned in my first post was created (scientifically generated) to eliminate all variables, as regards the source material used, when testing your system for sound stage width and depth reproduction.

       If your system doesn't reproduce (or- you can't perceive) what's in the media: it's NOT because the effects are a, "myth" (or any other of your excuses/obfuscations).

I've never heard any perception of front-back depth while listening through earphones. To be sure, I've heard plenty of left-to-right and in-phase/out-of-phase trickery with headphones, but that's about it.

I hear so much depth in my house of stereo, it's there, 100% real. The acoustic treatment and speaker positioning probably have most to do with it, but EVERYTHING does matter.

'Santana's first album has a very good soundstage with the illusion of depth.'

Thanks for your post.

I have a near field setup and  listened to the first track (Waiting) a few minutes ago. Especially the drums, particularly Ridebecken or Hi-Hat, changing position from back left to forward mid is clearly audible to me. Closing the eyes supported the illusion. Nice experience indeed.

Hence, my answer is 'no' to the OP's initial question.

(First time I'm listening to Santana intentionally)

Cristina Vane (alt-country with fiddle) makes very fine albums with depth and width. Doesn’t make the mistake of bringing the drums forward or using only left or right channel for instruments thereby creating a natural and “live” soundstage.
