Princeton’s 3D BACCH-SP Adio System

For years, David Chesky has stored me abreast of developments and updates to Princeton Professor Edgar Y. Choueiri’s BAACH-SP Adio System. Happily, the phrase is out. When I entered the room, none apart from Stereophile‘s Alex Halberstadt was sitting within the prime seat, receiving all the advantages of the fully-loaded BAACH-SP system ($37,780).


As Choueiri subsequently defined through electronic mail, “The BACCH-SP (the place the ‘SP’ stands for stereo air purifier) is a digital audio processor that yields 3D imaging from stereo recordings by permitting the listener to understand the spatial cues that exist in just about all stereo recordings. It requires a easy calibration involving a pair of in-ear microphones and an optical head tracker. The BACCH-SP Adio (Mk III) we unveiled in Munich is the newest mannequin. It is a single unit that mixes the BACCH 3D audio processor, a streamer, a DAC, an ADC (for analog enter) and a preamp (for direct output to an amp) in a single chassis.”




BAACH, whose trademark is registered to Princeton University, is an acronym for “the mathematical methodology used to derive the crosstalk cancellation filters (which permit the 3D imaging from the calibration) which matches by the title ‘Band-Assembled Crosstalk Cancellation Hierarchy’. ‘SP’ stands for Stereo Purifier. ‘Adio’ is the mannequin title; it stands for “Analog and Digital Inputs and Outputs,” and has a built-in DAC and ADC. There can be a inexpensive Dio system that accommodates a pure digital processor however lacks a DAC and ADC.” Not included within the system worth have been the demo’s JansZen Valentina A8 energetic audio system (above) and the Esprit Audio cabling.


As I settled into the seat immediately behind Alex—Choueiri stated I’d obtain roughly 60% of the system’s advantages—I skilled among the most pure three-dimension sound I’ve ever skilled. The solely time I heard something prefer it throughout my time in Munich was on the final evening of the present, once I loved Bayerische Staatsoper’s manufacturing of Verdi’s Aida from a chief seat in row 13 of the orchestra.


This system has come a great distance since I first skilled it at an audio present, most probably Rocky Mountain Audio Fest, what appears like a decade in the past. Here’s hoping extra audiophiles will get the chance to benefit from the BACCH-SP Adio System’s distinctive advantages at future reveals and demos, in addition to in their very own properties.

The solely time I heard something prefer it throughout my time in Munich was on the final evening of the present, once I loved Bayerische Staatsoper’s manufacturing of Verdi’s Aida from a first-rate seat in row 13 of the orchestra.
