Holographic imaging


Hi folks, is the so called holographic imaging with many tube amplifiers an artifact? With solid state one only hears "holographic imaging" if that is in the recording, but with many tube amps you can hear it all the time. So solid state fails in this department? Or are those tube amps not telling the truth?

Tbg,

I know I'm right in regards to reproducing what a person hears at a live performance. The way most recordings are miked, the geometry involved in detecting sound is different than that involved with human ears, I think that is a fact.

A system should have a good chance of reproducing to some degree of accuracy what the mikes actually picked up though, spatial cues included. That is the best you can hope for.

When you hear holography on a system for whatever technical reason, it is the perspective of the microphones that is being reproduced and this is always different than the perspective of the ears. That is a geometric fact I believe.
Ralph, impact and authority as you describe it is a very good way to describe what I mean by dynamics and related it to that is what I call microdynamics (there might be a better word) which is the ability to resolve small changes in volume and small changes in pitch that can sometimes be obscured - and that too might be related to distortion and/or poor S/N. These two aspects of reproduction are very important to me. I also enjoy the "holographic" trick as long as it doesn;t effect these; whether the holography reflects "live" or not.
I agree with Mapman here - the human ear is a much more sensitive instrument than any machine yet invented. No audio equipment I have ever heard or probably will ever hear can recreate the sound of a live performance.
TBG, you have a beautiful looking system, which I'm sure sounds wonderful - would love to hear it cuz I too have never been "fooled" into thinking a recorded performance sounds live (live-like yes), but if you system makes you feel that way, more power to you. Enjoy.
