Has anyone in Mi.acheived holographic imaging?

I was obsessed with holography for years and found the following things helped: Bugle Boy 12au7s in the linestage of my preamp, a single-ended power amp, decent noise-cancelling cables in a kimber-style weave configuration and, most crucially, speaker placement. They need to be a couple of feet from the back wall, creating a sound reflection that arrives at your ears a millisecond late and which the brain interprets as depth. It's a bit of a parlour trick. The speakers moreover have to be the EXACT right distance apart, EXACT right distance from rear and side walls, with the EXACT right amount of toe-in, and you have to listen from the EXACT right near-field distance, including height. That part is inexpensive, time-consuming and fun. It's incredible the difference just 4mm can make. I'd also add that point source dual concentric or single driver speakers will help a great deal.
Having said all that, there's often a trade-off when you're chasing a single goal like holography. I no longer use the Bugle Boys because I much prefer the sound of RFTs, and went back to my old Mission 770 mkIVs from Kef dual concentrics for similar reasons. I'm on a budget though, so I'm sure it's possible to have both wonderful sound as well as extreme holography. The wealthier folks here with more high-end gear experience will be able to help you.

Once one has good quailty gear matched well and the proper recording then it mostly comes down to room acoustics and how that affects the sound you hear directly from the speakers versus the reflected sound. It's a geometric puzzle unique to each room. That takes some time and a lot of tweaking to solve optimally. Some rooms will be much easier than others to solve.

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.
