Interesting, so Logic7 requires a different physical amp that the i8 lacks?
I wonder if it's possible to at least get the equalizer settings if not full Logic7. All we can change right now is Bass and Treble...
Edit: did some research, and found out on the HK site itself. Apparently, i series get 300W with "Class D Tech" vs. regular Bimmers that get 600W with Logic 7. It is the physical Amp. Basically what I had suspected: electrical power savings.

(Scroll towards the bottom for a view of quick specs and car speaker schematics).
I wonder now if it's possible to switch out the 300W HK Amp for the 600W HK Amp (Harman Kardon® Logic 7® DSP amplifier in Class-D technology with a total output of 600 watts). I don't really care for trading sound for battery electrical range.
