II would not say necessarily say better, but more efficient. You have to match speakers and amps together to suit ones ultimate goals. I am driving B&W 800's with 140 watt tube amps, and I could care less about any other speakers as I am completely satisfied. That is why I said, the low impedance curve does not matter with these speakers and good equipment. Pair of mono Octave 140 watt amps drive the 800's easily with clean, deep, dry bass. The best thing the original poster can do is to evaluate speakers in his own room and on his system to make the final determination for what the best synergy is. Perhaps the Plinius is not up to the job to drive these types of speakers at all, despite the 91db efficiency rating.
