How important is it for you to attain a holographic image?

Prof, not only have you identified a "holographic soundstage" but you have one; a rose by any other name is still a rose.

"Audio Holography" is nothing more than stereo taken to it's highest level; it's not something different. Using our vision as an analogy, whatever is on the disc or record, is what we're looking at. Two eyes that visualize everything from a slightly different perspective, is what gives the world depth and dimension.

Two speakers projecting slightly different views of the same sound, when perfected; meaning everything in the audio chain is of a very high quality, produce a visual image of the audio. While the gear produces a perfect image, the room distorts this image by not reflecting all the sound waves symmetrically. Trial and error will get us in the ballpark, but since we can not see sound waves, we need professional help, or professional measuring gear in order to perfect the sound stage with room treatment.


We have identified the elusive holographic sound stage, and since it was a team effort, I think it has been defined to everyone's satisfaction.

Each time we upgrade our rigs, we are moving in the direction of "holography" whether we realize it or not. However, it's only when we actively pursue room treatment, are we actively pursuing "Holography".

I experience holographic sound from many mono recordings.  One does not require stereo, 2 channel sound to achieve 3D sound.   My best mono recordings have great depth and open soundstage, including wall to wall sounds as the recording permits.  What they lack is specificity of instruments depending on the recording that stereo provides is inconsequential.  I'm sure you'll claim that mono has only 2D sound.  

Fleschler, just for you, I searched until I found a "Mono" of some of my favorite music; "The Clifford Brown Quintet" featuring Max Roach, Harold Land, Richie Powell, and George Morrow on bass; with Clifford Brown on trumpet of course.

This music was recorded at Capital Studios, Los Angeles, 1954; Although it's in "Mono" the recording quality is fantastic, but it's in "Mono"; that means one big fat center channel spread across my rear wall.

I'm glad your rig is producing holographic sound with a Mono record, mine isn't.

Those Clifford Brown recordings are fabulous in every way!
