None of which supports your assertion that the quoted distortion figures are being massaged by being quoted into a higher impedance loads.
Of course, an amplifier has lower distortion into higher impedance loads, to a point. LSN distortion is well known. However, the datasheet has several graphs of distortion vs frequency or output power level, and in all cases, they specify the load impedance (4 or 8 ohms). There is no indication that they are lying in the name of specsmanship; there is no reason to assume that this IC won't meet the published specification when properly implemented. So please, let's not casually throw accusations about without the data to back them up.
