Same here - I preferred the AFC over EFC. Never auditioned the upgrade (EFC 1.1), and read somewhere that it is a significant improvement.
Good point! With the new tuning, they've smoothed out the bump-dip-bump in the low mids that I thought made the mids sound odd and artificial. That change is likely to help quite a bit. Zappaman should definitely try to audition them then.
