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?

Ah - the rationale shifts. Last time I looked it was about physics - i.e. doppler shift. Now we have moved up in alphabetical order to physiology - how humans percieve sound due to the structure bilateral nature of our ears. What a compelling argument. Pay no attention to that man behind the curtain.
Goldeneraguy, Roger's design is in my opinion far superior to anything I have ever heard. I don't teach students what audio to buy but rather teach what research shows. I am not in the science of amplifier circuits and know none posting here are either. I don't know how Roger conceived of this Doppler correction circuit or even why it has so improved over time, but I do know it has.

He is proud of what he has accomplished and the proof that it works. He is honestly trying to convey his thinking which underlies his circuit. I have told him that those who demand an explanation based on currently accepted terminology are not interested in sound, so he should not bother with them. None seem capable of defending their personal amps or those they make. But they demand it of Roger and he foolishly responds.

This is a great amp.

Tvad, I probably started the slide by suggesting that electronics can contribute to holographic imaging. That brought the usual response from you know who. I think Roger was merely trying again to explain his ideas. He is too sincere and insufficiently dismissive of ignorant responses for his own good.

I only ever said that it sounded outstanding. Some did ask why and I gave a response limited to my understanding even though for me it did not matter.

Roger, of course I agree that things happen in between the microphone and the loudspeakers that alter the perception of the recording - some intentional, and some not.

Aside from your assertions, I do not know of a single source that ascribes any perceptible alteration of the signal to doppler distortion in amplifiers. Based on your description of this distortion, and published psychoacoustic research on human hearing characteristics, I do not believe the distortion you propose would be audible even if it did exist.
