The BACCH-SP adio/dio

The BACCH® Stereo Purifier (BACCH-SP) is a state-of-the-art digital audio processor featuring BACCH® 3D Sound technology, developed at Princeton University, which purifies loudspeaker-based stereo playback by removing the crosstalk that degrades the 3D spatial cues, which exist in most stereo recordings, yielding strikingly realistic 3D sound presentation from any pair of stereo loudspeakers..

STEREOPHONY REINVENTED

True 3D imaging with breathtaking realism

The BACCH-SP is also a streaming endpoint, with optional critically-acclaimed DAC/ADC/preamp stages and a suite of advanced DSP modules that include head tracking, state-of-the-art room correction, 3-band crossover, and speakers emulation through headphones.

The Grand BACCH-SP is our flagship model, featuring point-to-point hand wiring, extensive I/O options, plus all DSP software options, 6-channel DAC, 6-channel ADC, and integrated preamp. The BACCH-SP adio is outfitted with the most widely used analog and digital I/O, featuring highperformance DAC and ADC stages, and preamp in a compact handpolished chassis milled from a single aluminum block. The BACCH-SP dio is a purely digital processor with no DAC, ADC, or preamp, but housed in the same enclosure.

BREATHTAKING 3D SOUNDSTAGING through individualized tonally-transparent crosstalk cancellation filters (BACCH® filters) designed from quick calibration (impulse response measurements) made by the listener using calibrated binaural microphones placed in the listener’s ears.

REAL-TIME HEAD TRACKING automatically adjusts both the 3D soundstaging and the room correction so that they remain perfect as the listener’s head is moved.
