+1 votes for pre-amps.
I would also note its not just a matter of impedance matching. I have a dCS Delius that, at least according to the specs, should have had no problems driving my ARC VT100s. But, I had the classic "no pre-amp" problems--music lost punch, dynamics. I slapped in an ARC LS-8 and the world became much better.
YMMV.
