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?

Roger, you may or may not have discovered an interesting phenemonon. I am not convinced that you have made such a discovery by the case you have presented. I am even less convinced that you have developed a suitable cure, and that just might be the crux of it for me. I do look foward to auditioning the H-Cat.
Though it might be an anthema to those who fancy omni-directional (or those trying to aproximate that goal) speakers, I can't help but wonder what omni's might sound like in a heavily treated room that would mitigate the surrounding reflections.
I haven't heard the H-Cat gear. I am dubious of these claims. How does one determine just where in the circuit these errors occur? Does the circuit allow for the approporiate correction to be applied in each instance of error, and is that necessary? If in fact these errors are in evidence, wouldn't a (with prejudice aside) digital input read compared to a digital output read and correction make more sense?
If these "doppler" errors are indeed there, and are "microscopic" how does one determine where they occur, read them at each occuring stage, and how is their (I'm assuming) delicate effect, effectively corrected and how is that delicate(?) correction calibrated at each stage?
In regard to the effect of moving the listening position in a typical listening room, I would guess that the issues of the sound changing due to the change in effect the room would have, and the issues of driver intergration might swamp the effect of such "doppler" issues.
I have noticed that sometimes when I increase the volume level, besides the sound getting louder, the soundstage seems to get bigger. Despite what might appear to be an obvious deduction, I don't necessarily get the impression that I am actually closer.
Am I to understand that these "microscopic" changes are inherent in all other amplifier technologies, including typical ss, tubes, switching and conversion (TacT) except the H-Cat? Am I to understand that the H-Cat can accurately correct the unmeasurable and furthermore do so on the fly? Am I also to understand that these "microscopic" changes might be variable depending on up stream components, and that these "microscopic" changes happening at various points in a circuit are either consitent in nature or that the knob on your gear allows (without any digital measurement or comparison) the user to either coordinate these "microscopic" changes and/or sum and correct the "microscopic" changes without any form of measurement?
