Comparing the before and after samples, there is definitely an audible difference for this pair of ears. To be fair, I listened to the after sample first and it sounded like regular old Skrillex to me. I scrolled up and listened to the before sample and noticed that the bass was deeper and more harmonious with the higher end frequencies. Basically, the original sample has a "subsonic" vibrations that resonate in time and "harmony" with the higher end sounds. (Also, I'm using higher-end earphones with custom ear canal sleeves to listen.) So, I probably wouldn't have noticed anything unusual if I'd only listened to the modified bass drop, but I can hear the difference when comparing the two.
