What does this tweeter look like with a more conventional AB style amp tested the same way?I voted poor as it has load dependency. My experience with that ranges from making a speaker brighter, to making a speaker an unlistenable mosquito sounding machine. No excuse for it anymore, it needs fixed in these cheaper amps.
This is how c-notes reacted to an A07 (only tweeter is measured here). Totally unacceptable and should not get a pass.

Then to make it graphically easier for the likes of me to understand and *see,* I'd ask again that the simulated speaker load comes back out and the frequency response of such amps into this load is presented as it is in Stereophile. The graphs here suggest that it's only over 10kHz that response errors occur as below that, the rsponses lay directly on top of each other.
