Not sure of their electrical characteristics - are they very low impedance?
Very late reply (I stumble upon this thread).
Omega and Epsilon are
roughly 4 Ohms, very flat impedance curve,
especially in the bass. (See impedance and phase curves hereafter.)
Initially, while I was a student, I owned a pair of used little Omikron, that I used to power with an little Audiolab 8000a integrated amplififer, which easily did the job (although the Omikron deserves
much better).
Analysis are very robust panels, partly due to the damping of the bass panel ( -> no ribbon crackling). Impossible to make them 'flap', says Christiaan Punter (Hifi-advice), in his recent review of the Epsilon (he tried to push them by playing very loud: no issue at all).
I have never encounter the slightest issue in 22 years (first Omikron, then Epsilon).
Around 2016, I welcomed at home a person who wished to hear Analysis panels, as the brand was not distributed in the country. (I did not know him. A few years later, he became Aries Cerat importer* for Benelux, used to sing in a choir, attends classical concerts, etc - not exactly a deaf).
He was so impressed by the Epsilons in my humble system and room that he ordered a pair of Omega two days afterwards (and decided to sell his Rockport Avior).
* (eight years ago, I bought my Aries Cerat Incito preamplifier, ex-demo, as he wished to upgrade to the new-at-that-time Incito S. He had no dealer yet and he initially ran his business as a dealer. Alas, I have never heard his Omegas
in his room with
full Aries Cerat electronics, a pity.)
Omikron: €9200 (6 Ohms - 30-20KHz)
Epsilon: €13800 (4 Ohms - 26-20KHz)
Omega: €19000 (5 Ohms - 22-20KHz)
Impedance & phase curves
EPSILON
From 20 to 100Hz, the Epsilon is a true and completely steady 4-ohm load. The 7.3-ohm peak occurs at 550Hz essentially at the crossover point. Above 3kHz, the load turns 3 ohms. The upper phase plot is equally benign and, perhaps most salient, both curves are as linear as a dream for the bass panel.
