You claim that I said something but then you provide your own words, not a quote of what I said. And then some of your made up words are false. The statement "Certain HD characteristics could have an association with certain -other IM- characteristics" is a vast understatement of the facts of the matter. There is a fixed relationship between any HD characteristic and any IM characteristic that is dependent on which characteristics you choose to study the relationship(s) between. So, it is not a matter of "could have" it is a matter of *does have*. The comparison is highly flawed because it is susceptible to cherry-picking. Furthermore, It is not uncommon to have measured THD that vastly understates the nonlinearity that is present by means of low pass filtering. For example estimating nonlinear distortion above 10 KHz in a CD player by means of measuring harmonics is false because the harmonics are outside the natural bandpass of the CD player. But many IM products are sidebands of the signal and thus are nearly the same frequency as the signal and thus difficult or impossible to filter out. The end result can easily be massive audible and ugly aharmonic IM with no measurable HD at all. Just ignore the built-in filtering starting around 20 KHz. I know that euphonic distortion is a canonical part of much golden ear dogma, and that many true believers in anti-scientific audio will fight the Science to the death. The primary reason why equipment with audible harmonic distortion are tolerated is that the high distortion only happens under rare operational circumstances. One can see this kind of cherry-picking of demos at just about any high end audio show. SET amps with high full-power distortion are demoed with high efficiency speakers at lower listening levels where there naturally is not all that much distortion. The loudspeakers used are complementary to the SET's poor performance into loads with varying impedance by contouring the speaker's impedance curve to boost the mid bass and drop the upper midrange, creating a warm sound. It is all a set up to perpetuate the fiction that measurements don't matter. This helps the same dealers sell magic cables with no relevant audible measurable characteristics, which is confirmed by means of sighted evaluations. Darren, why are you trying to be complacent with all this? ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=106914 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
