Wow. The ignorance and hostile attitudes on display in this thread is kind of shocking. Spread those speakers out? So others can enjoy? Sorry Jack, but stereo only really works for ONE person. Wider isn't always better. Certainly, if one enjoys maximizing their enjoyment of two channel, why shouldn't they? I still maintain a separate high-end system for music with Carver ribbon speakers. Only recently do I feel my home theater setup is starting to approach it for two channel music, but it takes seven speakers out of 18 here (matrixed front wides plus active mixed heights for a dialog/soundstage lift and expansion plus the mains and subwoofer) in "stereo" mode to achieve what the Carvers can do alone with Sonic Holography on terms of size, depth and surrounding soundstage.
For Home Theater, panned dialog matching the screen should be the prime concern, not spreading your speakers out as far as possible.... I don't know about trying to demonstrate the system over YouTube, though. I wouldn't try to demonstrate Carver's Sonic Holography over YouTube.
Certainly for Carver's Sonic Holography, you don't need special recordings. The goal is the same regarding inter-aural crosstalk, though. It destroys stereo's full imaging potential.
To OP. I use Carver's Sonic Holography with Carver AL-III 6' ribbon speakers (with a custom designed active crossover designed by a former Carver engineer) in my music room/recording studio. Generally speaking, it's a night and day improvement over plain stereo. The sound stage widens and wraps up to 180 degrees of the listening position. I've never had one person claim the sound was 'bad' off center either. The imaging isn't correct, but it never id off center for ANY stereo setup. To the contrary, one guy asked me to put him in my will for the Carver speakers he liked them so much. Yes it can be used with modern Atmos, etc. It just widens the front channel soundstage (never a bad thing).
