Theoretica Applied Physics BACCH-SP adio 3D Sound Processor

Around 1996 I bought my first real stereo system up in Toronto. I think I spent about $7K. I remember describing the system to my work colleague and she was shocked at what I paid. She said that I was crazy to pay so much and I countered that it was a lifetime purchase. I said I would only upgrade the system if something crazy and new came about. This was the time of CD's and perfect sound forever.

My hypothetical argument to her for a future crazy upgrade was, if say in 20 years, they come up with a way to project in 3-D the performers into your room. I said I would be all over that system. Well I was wrong about the amount of upgrades I would do over the next 30 years, but I may have been correct to predict that 3-D performer thing.

Back in time, while working a room for a high-end dealer at the CES in Las Vegas, I heard a demo put on by Sony. They were using a processor in a room with six speakers, two in front, two on the sides, and two in the rear. I'll never forget the experience. The music was a performance recorded live in an intimate nightclub. The system literally put you into a seat right in the middle of the room, clinking glasses, cocktail waitresses, and all.

BACCH is not marketing hype. There is actual scientific basis behind the implementation.
BACCH is partially based on Ambiophonics, and it is basically ambiophonics + head tracking. I use ambiophonics DSP in my listening setup, and it is fantastic. Imaging solidifies quite a fair bit, even with cheap computer speakers; clarity improves (depending on quality of speakers and setup). On my Audience Ones, which is already an imaging champ, the sound stage is wide and deep with excellent layering.

I imagine with head tracking and additional DSP, the BACCH should be even more impressive.

@andrewinukm Are u referring to the Audience 1+1? I had the latest version of that and had a heck of a time getting the setup and imaging to work properly in my small office. It improved once I added some room treatments but I decided to keep the LS50's over the Audience 1+1 V3. I always felt I did not get the best out of the Audience with my setup/room.

Getting back to the BACCH the price range for their 3 products is $20K to $50K. It will be interesting to see how this tech moves forward and into a wider set of products. The description of how headphones are made to sound like 2 speakers in front of you is interesting to me. Not a fan of how headphones sound now but would be interested in headphones if they sounded like floorstanders.
