Seems odd to me but can I ask why you are purchasing these amps that are over $3K without even hearing/knowing they can drive these evil Kappa 9’s
Good luck btw with these IcePower based modules https://ibb.co/hZJN3q5
Good test, looking forward to it and your findings, and hopefully anyone else’s that maybe present, if you could get them to furnish their opinions also.
