You'll need more power than any of those provide. If you must use a receiver, try an Arcam AVR300 with the 6/7th channels bi-amped.
I briefly powered a pair of S5e with a RSX-1055 and the sound was anemic at best. Even with more power I didn't find them the most dynamic sounding of speakers, so perhaps they may never open up for you.
