Strange stuff..
As I noted above, I shuffled a whole bunch of amps into and out of a system featuring Parsifal Encores. My Cary 300B monos, which work wonderfully with many other speakers - including Merlin VSMs - couldn't drive the P/Es at all. An early Atma S-30 produced so little bass, I was concerned that either the speaker or amp was broken, till I switched them to other partners and they performed well. IME, the P/Es have worked welll with modestly powered SS amps, but have tortured exotic, low powered tube amps into real distress.
Just my experience.
