Bacch Dsp, True stereo?

@tk21 

Amazing comment. Pretty much reinforces my belief that while the underlying engine might be truly wonderful, it's always the implementation interface that makes it terribly unpleasant to deal with and not worthwhile.

About not working well with all speakers is a huge problem, and of course music selections are kind of important. I have lots of recordings that sound absolutely wonderful even without this product innovation. 
 

Why the designers spend all their time with the core engine without giving regard to the interface and issues encounter upon implementation is beyond me. Dsp tools that are out there are also the same, the backend is probably fine it's just the front end that screws things up and frustrates the hell out of people. 
 

I have been interested in this subject most of my audiophile life. Decades ago I heard a demonstration of a Yamaha DSP-1 Sound Field Processor and I was blown away. Since then I have acquired several processors including a Carver C-9 Holographic Generator, BSG QOL, Black Ice Foz SSX, and a DSP-1. Someday I expect to write a review of these processors in case anyone else is interested. I have not heard the BACCH system but I look forward to it. I've got a spare MAC laptop that I could use but I would like to hear it at an Audio Show if possible.

For now I'll discuss the BSG QOL processor because it's my favorite and there is good reporting on it. The unit is very good at expanding depth of the soundstage. You can almost see the instruments placed in 3 dimensions with much more depth than standard stereo. I really like it and I run it most of the time. Whenever I compare components I bypass it because it makes everything sound better. I like it so much that I bought a spare in case this one breaks.

There are several good articles in the trade mags about this processor and they go into the theory behind it. If you are interested you can learn more about this subject in layman's terms. Here are a couple links: Stereophile BSG  and TAS BSG Review

Would it not be better to have heard a  BACCH system and formulated an intelligent option about it?

@curiousjim Its clear the OP has already formulated his completely uninformed opinion and is now just cherry-picking responses that reinforce it while disregarding all the positive responses.  Plus, he’s obviously done zero research on the product or made any effort to actually learn anything about it.  But it is interesting hearing the feedback from people who’ve actually used it, so at least there’s that.
