I'd look into amps- all tube or hybrid with a bit more power, small room notwithstanding. I, too, have Dynastats and they do like a bit of power as one might expect with electrostats. Currently have an upgraded Counterpoint SA-220 (along with an all-tube Audible Illusions pre)which seems to work very well. On the off-chance that you happen to be in the San Antonio area, you'd be be welcome to drop in.
