System 700 / 100M

This is a question to those who have knowledge about Roland
System 100M schematics.
I have heard from quite a lot of persons, that the Roland System
100M sounds quite "flat" and "thin" in comparison to the
System 700. I'd like to know whether this is true and what are
the reasons.
I have the System 700 schematics at home (thanks, M. !), and
I found this is quite basic stuff, with the ultra-expensive uA726
exponential converters in the VCO's, however (like in other
Roland synths of that area). The filter seems to be a common
State Variable one. The VCA's are nice, with OTA and discrete
transistor buffers.
There are a lot of other special modules of course, but the
basic signal path seems to be rather common to me. So what
the hell have they changed in the 100M that it should sound
so much weaker?

Any details welcome, thanks in advance,
