inverted phases on iaudio x5

In big loudspeakers playing loud you might be able to FEEL the difference if the sound of a beating bass drum is inverted or not.
Otherwise probably not.

That really makes no sense.  Your sense of touch is no more phase sensitive then your ears, low frequency or otherwise.

Yeah! I'm happy there's at least one other guy in this forum who's got the idea. Basically, I wouldn't even want to claim I could tell an "inversed" bass from a non-inversed one. But your hint goes in the right direction: strong pulses. A strong positive low frequency pulse, immediately followed by high frequencies of low energy simply draws a different picture in my head than the same sequence started with a negative pulse. There's no right or wrong, it's just different. The explanation is that within a certain range your ear is converting mechanical energy "symmetrically", that is you can't identify a constant sine wave of being started negative or positive. Even more, with listening long enough - and long is meant to be in the range of microseconds - your ear will sum up any a-symmetric influences to just one let's name it average hearing experience. Things become different, though, when your ears are reaching a range they can't cope with, when there are no (or no close) signals of the same amplitude but opposite polarity to compute an average value from. If you ever have the chance to lift yourself up a 100 floors in a fast elevator - mouth and nose shut - and then back down again you might understand what I'm talking about: It even HURTS different.

Look, come back with ABX test results, but stop with the hypothesizing. If anyone posts one more theory in this thread, in favour of EITHER SIDE without a test result, I'm deleting the post or even the whole thread. Not even locking. Thread gone, period.

Do some testing. It's not that hard, and it provides meaningful results.
