I’ve been working on the installation and tweaking of the Bacch4Mac.
It creates a very large three dimensional sound stage but it is complicated to set up. They walk you through it but it took me three sessions to get it right.
It works like sound canceling headphones eliminating cross talk between left and right channels by eliminating the “bleed” from the left channel into the right channel and vice versa only it’s a lot more complicated than that. I like it because it works on any stereo whenever recorded and produces a much more spatial sound field.
