After many hours of adjusting, changing, etc., more than 150 hours of burn-in, and lots of listening by me and my Golden-eared friend, I decided that IF the 10Es are better than the S7s, it's by very little and sometimes the S7s are slightly better than the 10s, so the 10s are going back.
Oh well, it was worth the time and effort.. LOVE THOSE Super-7s!!!
