In all your post above mijostyn you accused me of not having listen to a good stereo system in my life , as the one you claimed to have heard yourself younger with your friend who ignorant as you said he was, anyway assembled one by pure chance ... Sorry but very good stereo system dont exist much among ignorant consumers by mere luck in their living room with no electrical, no mechanical and no acoustical control...I know this for a fact ...
Then you claimed to correct me but instead you are saying a falsity : crosstalk FOR SURE exist between the speakers as TWO competing sound source for the ears/brain , and is a perceived effect because the two PERCEIVED speakers interacted as i said and the ears/brain loose spatial information because of this interaction differential time between the ears from the incoming waves competing between the 2 speakers ... You did not understood my post and you patronized me saying falsity , me i used a simple mechanical device experiment to sense the difference between more and less crosstalk as i said , then i know the destructive effect of crosstalk first hand on the imaging ... But it is impossible to suppress crosstalk mechanically as i did for syre but only play with it ... It takes the Choueiri Filters to suppress this competition between two sound sources differently perceived by the brain through the two ears canals .... Crosstalk dont cancel as you claimed ....read about Choueiri here ...
You said erroneouly that crosstalk will cancel in stereo system misunderstanding the problem completely because crosstalk is not only a phenomena explained by the two ears differential time difference as you said but also by the competition between two sound sources ( the speakers) as in all stereo playback ... In a live natural environtment as said Choeiri there is not two birds to be heard but one bird ...
Then you misunderstood completely what is crosstalk ...
The crosstalk you mention is not between the speakers, it is between your ears and this remains the same regardless of the sound source. live or reproduced. The effect cancels out.
Now this is what Choueiri explain :
«There’s a problem, Choueiri and many others maintain, with the way that stereo recordings have been played back for the last 70 years or so. “If you go out in the forest and you hear a bird singing, it’s not because there are two birds singing,” Choueiri explained with his characteristic intensity. “There’s one bird singing.” Stereo only creates the illusion of localized sound by manufacturing a phantom image “and your brain doesn’t believe it.” In life, a sound is precisely localized because of a slight difference in the arrival time at the right and left ears, as well as slight differences in amplitude and tonality that are attributable to the physical presence of the listener’s head and the shape of his or her ears. With reproduced sounds emanating from two loudspeakers, these relationships are considerably degraded, especially if the listening environment introduces reflections. Each ear isn’t hearing what it’s supposed to—inter-aural crosstalk is spoiling the party.»...
«the BACCH filter aims to solve the major well-known shortcomings of previous XTC schemes. Choueiri developed a sophisticated head-tracking mechanism that considerably enlarges the “sweet spot” for the primary listener and obviates the need to sit in your chair as though rigor mortis has set in. More critically, the BACCH filter doesn’t introduce any coloration to the signal. How is it done? At the most basic level, Choueiri found a way to shift XTC processing from the amplitude domain to the more “subliminal” phase domain, a manipulation of the signal that the brain is less likely to notice. The BACCH filter is the central feature of Theoretica’s commercial audiophile products.»
As you can understand Choueiri filters is not to be confused with any XTC scheme ambiophonics or others and has nothing to do with your equalisation decvice at any price ... You cannot suppress stereo crosstalk between the two speakers with conventional equalisation , mechanical or electronical ... Read more Choueiri to understand ...
Now what you said about headphones is not false but not true either ... Why? Because unlike your simplistic claims, all headphones are not equal ...
Anyone who has been to a live modern music performance like NIN or Tool knows this. With headphones it is missing entirely, like taking a shower with a raincoat on. Your opinion manifests because you have never heard a state of the art system that can image at the highest levels.
my AKG K340 gave me a speaker-like imaging out of my head , for sure it is recording dependant , but the imaging is there with holographic depth ... If you want to know why read the Dr. Gorike patent as i did before optimizing my K340 ... I succeeded after 6 months of experiments ...
Me i gave arguments i dont attack people ad hominem as you did claiming there is no audiophiles who listen with headphones or accusing me to have never heard a true imaging , but claiming at the same time that your past friend did that by pure luck with his system created by ignorance and randomness ... Did you perceive the absurdities in your post ?
