High value, giant killer speakers?

@213runnin that wasn’t my experience at all. Plus numerous threads of them going into protection mode on semi-difficult loads.

At what starting point does a loudspeaker have to be to be a 'giant' killer? Obviously the LRS is, but can a speaker that costs $9000 be deemed as such? The new Elac bookshelf loudspeakers as heard at the RMAF this year certainly are slayers to my ears.

So subjective. 

Seas A26 kit

they replaced my Harbs shl5plus and im just as happy.

Audiokinesis (Duke) has made giant killers for a long time.
His Dreammakers are better than many speakers that cost 3 times more. They are also easy to drive which always helps keep amplifier distortion down. Very neutral, nice extension, excellent soundstage- hard to fault.
