Is this just a marketing gimmick or real?

Listen to the difference

probably real, my Panasonic head unit has something similar, it makes music sound considerably better. But when I played a song that has very defined left/right separation I noticed it didn't sound that good. You can't make a shitty mp3 sound CD quality but with some tweaking I could see this making a decent sounding mp3 sound better.

Sounds like it plays with the EQ settings.

Almost just sounds like the equalizer was raised across the board no?

No....if you notice the frequency response graph...

MP3 compression doesn't encode much past 16khz. What is there, at all bitrates except 320kbps, is terribly artifacted (and you don't want to hear it anyways).

My question is: how are they "filling in" that unencoded spectrum?

I will take an Alpine unit with professional RTA tuning any day.

90 percent of people over 25 can't hear over 15khz anyways, whats the point?

Sony has the same feature as well, iirc.

I am very rusty on my car audio but back in my days when I had my car at a competition my car was tuned without the feature Alpine has on their units. From my memory the feature over produces the sound which they consider proper for a high quality sound system. I think it pretty much makes the sound too bright according to the judges.
