3-Dimensional Soundstage

We must not confuse an unnatural timbre sound ( from many speakers right out of the box, milhorn is right here  ) and the spatial information encoded in the recorded acoustics and destructed by crosstalk ...Choueiri BACCH filters is not multichannels , this is for sure another interesting debate ... But BACCH filters will also improve timbre perception and not only the spatial qualities, provided the right set of measures for ears and head are well done and provided that the room acoustics is optimal ....

Immersiveness or the way the listener envelopment (LV) is realized without being detrimental to the sound source width (ASW) is another very important characteristic of the sound experience as much as imaging and soundstage ...

Then redesigning speakers as milhorn did , or creating a multichannel system, so good it could be, is not enough ...I am with Dr. Choueiri articles about that ...

Timbre experience ask for more deep acoustical controls ....Choueri explain it well ...

I must specify that this is only my opinion ... I dont own the BACCH filters nor a multichannel system nor the Milhorn speakers ...

@mihorn I think you may have got the "unnatural" mixed up...

How the sound materializes from the instruments and are perceived by the ears thereafter (like flowers blooming and closing perhaps inside a 3D dome of space)

Thank you for detailed kind explanation!

Yes. I know the sound images blooming and disappearing in the air. Those effect and quality make me stayed in audio for decades. My system can do that better than any other systems since my systems background very quiet. I had Avalon Eclips and Jadis Defy-7 almost 20 years ago and those were pretty good, but they are not even close to what I have now.

What I mean by unnatural sound is a left speaker in below. Alex/WTA

If you want a true three dimensional sound stage and imaging from two channel stereo there is really only one game in town. BACCH SP. 

Great post!

People must read about crosstalk and Dr. Choueri research ...

They did not understand generally what are the acoustic conditions of musical and three D acoustic experience in a system/room/ears ...No the solution is not owning a multichannel system so good it could be !

Because the 5 aspects defining a better timbre perception are not related to the number of speakers at all ...But these aspects must be improved by the crosstalk controlling filters that then will improve the spatial qualities of sound then the naturalness of timbre perception as recorded initially ..

Acoustics rules audio gear  not the reverse ...

"More critically, the BACCH filter doesn’t introduce any coloration to the signal."

Not supported from the videos presented here.

Additionally, if the primary intent is to remove crosstalk, why do they recommend it for headphones where crosstalk is not an issue, and why shouldn’t one just buy the best headphones out there for far less $$$?
