Totally agree, these speakers need power. And not just power, but dynamic power. Most manufacturers shy to declare their amplifiers behavior into 2 or even 4 Ohm. But lab tests show that in that case a lot of units fail and show even less power, than into 8 Ohm. When this happens, it doesn't really matter, what absolute power numbers are. It won't do the job to control these speakers. I think that phylosophy was introduced by Dan D'Agostino for Krell amplifiers, but not sure really.

On the other hand, this is German brand, just like Canton. More to this, at Canton they use Audionet (also german with some similarities in approach) amplification to test their speakers in the head office (can be seen in factory tour articles). Now that this brand no longer exists, it's interesting if they will move to something else.

Yes........ have to admit to being surprised at how much power they really need to sound their best. Being primarily a monitor speaker user for the past 20yr, the 9K's needs are different than their predecessors in my systems. Not a bad thing. Just something that took almost a year of different amps to discover.

Wonder if Ivan could help on this with his Accuphase gear? Believe he has more than one Class A amp he could use to let us know his findings.

EDIT: Here is part of the answer to your Class A question: https://www.audioaficionado.org/showthread.php?t=44864
