Has anyone in Mi.acheived holographic imaging?

Jfg : "It's baffling to me why dealers don't use this as a selling point."

I believe it would be counterproductive for dealers to advance the concept of holography to their customers. Dealers have to move their inventory quickly; they have to change their showroom appearance continually to avoid looking stale.

Customers, on the other hand, for the most part want "plug and play." If you tell them that they have to spend many months, if not years, to get it right (and without dealers' assistance since dealers are in the business of selling things to make a profit) and considerably alter their living room appearance to do it, most customers will look elsewhere.

What dealers can do is promote the greater ease and simplicity of "surround sound" instead.

Would be a good New Year treat to hear. I have been looking for the same in and around New York City for about 5 years. Budget is not relevant - you can achieve modest levels using moderately priced gear. Expensive equipment merely sets up the process for louder volumes, requiring bigger rooms. However, I generally find that the bigger speakers, while being able to "sing" at louder volumes for which they are designed, have difficulty reproducing more intimate voices and sound stages.

Jfg, I believe you are on the right path re room treatments. Holographic sound reproduction requires high precision and focus of sound waves, since we are operating within the stereo format.

Hence, Uberdine is correct, in my opinion, re exact speaker placement and alignment. His 4mm variance is about my 1/8" experience with speaker adjustments. I also agree with Uberdine's suggestion re using point-source drivers for the above reasons, as well as vacuum tube amplification, since it seems to remove many of the veils plaguing solid-state amplification. I do not agree, however, that the process is "inexpensive, time-consuming and fun." It is very much not fun, but annoying, frustrating and marked by setbacks.

I have not seen holography done with any degree of credibility in or around New York City as yet, so I am doubtful that any of us will experience it, unless we reproduce it ourselves. Such an endeavor is far too time-consuming and destructive (decor-wise) of the sound room space.

If that is true, Jfg, then true holography is even rarer than I thought. That level of advanced holography would require near absolute control of the forward sound waves and their reflections off the walls.

I met only one other person who has insisted that what you described was something he heard literally decades ago (and he insists he remembers and is also seeking to reproduce that phenomenon). I thought he was half-joking.

This near total control of propagating stereo sound waves to re-create not just the original event but also the illusion of ambient waves is very complex. It would require the melding of art and science.

You are therefore only the second Dr. Frankenstein The Audiophile that I have met.
