In the Thread: The mystery of AmpX
Post Subject: A mystery indeedPosted by Edgar= on: 5/1/2026
Following with interest. I love a good mystery.
I'd like to have a crack at attempting to decode what you might be playing with over there. It's a long shot, as details are scarce and the subject nebula but let's see.
I too am working on a somewhat "unified" theory for audio experience. I believe the key to a metaphysical musical experience is harmonic structure. I've alluded to this before on this site. Think DC building to square wave. Get that right and your body does the rest.
I may also sound like a hallucinating idiot but hear me out. Here is a link to a brilliant video by Brian Haidet. I have referenced him before about the speed os sound and whilst not directly related to this topic, the way he demonstrates resonance is a really good analogy for how harmonics build in our rooms http://tempuri.org/tempuri.html
Now notice in the video, if the timing of the pulse is slight too early or slightly too late, the resonance doesn't build? The same thing happens in our listening spaces. if our playbacks phase is not incredibly coherent harmonics will not build.
When done right, the harmonics will continue to build in frequency, in the room, beyond the upper limit of the playback. Up, up and up. Very desirable.
How does this relate to ampX? My guess is that the topology can somehow adjust that "pulse" to be in-front of the wave or behind, altering how the harmonics build in room. Maybe somewhat like moving a midbass channel micro amounts forward or back, to adjust the playbacks front edge, but instead of adjusting absolute phase (of that channel), it adjusts where the harmonics sit on top of each other.
Am I in the ball park? Does any of the above speak to the phenomena?
