Has anyone in Mi.acheived holographic imaging?

Sure thing. Those are the things I have heard over the years that has probably most influenced my buying decisions.

I think the fact that the room volume was so much greater than the volume required by the sound stage was the major contributor. I must say that I was impressed by the X12s. Now they often sell for ~$700. I think they do best with 100wpc SS amp.

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.

I respectfully disagree mainly because I have yet to meet a dealer or

Holographic imaging.Fact is if I had not "seen" it I would still be listening
to Bose.lol

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.
