Do active speakers have high THD amplifiers?

A shit load of opamps in active xovers in the signal path of the mids and highs to me sounds like it does the opposite

You cannot replace missing harmonic structure with a tone control. 

Naaa sorry not with massive ML Neolith paneled Monolith ESL’s from lower mids to highs, it says what right and what’s not to my ear. And a good passive xover sounds far better than any active I’ve tried
I wanted to try the fully discrete Nelson Pass First Watt Active XO but none available any more, that "could" of changed my mind.

Just to add to my first answer, it’s not that active xovers seem to my ear to add any distortion, but more that they "seem" to strip the "harmonic structure" from the music in the mids and highs and leave just the (admittedly "clean" fundamentals).
This is why I feel they sound thin from the mids and highs and leave things sounding too "sterile" for my liking

All active xover’d sound impressive at first, but then quickly always sounds sterile and thin to me in the end from the upper bass to treble, low bass is fine. I believe it’s because of too much electronics and opamps in the active xover that the signal has to go through
Every time I’ve put my Martin Logan Monoliths (with Neolith panels) through any type of active xover that’s what happens to them. Best sound is always 3rd order passive xovers for the panels 150hz up, and 4th order active for the 12" bass unit 150hz down.
