Do active speakers have high THD amplifiers?

Good amplifiers tend to be the norm rather than the opposite. If you are buying active speakers from a reputable manufacturer, I'm sure it's a well measuring amplifier.  You should listen to the combo and go by that more than specs.

The answer is No.

But, how does it taste.  I watch some posters banter about the ingredients and then recipe for perfect sound conjuring up concrete conclusions.  Fact is, one could gather the same ingredients for a dish and come up with a completely different result.  And that is what we do here, cook up aural dishes.

It's all in the execution.  Recipe calls for salt.  Kosher salt? Celtic smoked salt? Himalayan pink?  Alton Brown would take the same recipe and crush us all.  Execution will always radically change the end result.

When one has actually owned and operated 20K active speakers (studio monitors/floor standers) and compared them directly with 20K of amplification and passive speakers and states "I like passive with amplification better", well then fine.  I can accept that, I've no real skin in the game.  I've already played the game and decided for myself.

I simply do not read that out of the postings.  I encourage more critical thought and an upscaling of information.

Do active speakers have high THD amplifiers?

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
