I used the 5400 & 5500 on Dynaudio 4 ohm speakers, which are pretty stable, the amps rocked them without breaking a sweat.

Also, Bryston are rock solid high current amps which are in an entire higher level from Adcom.
Both the Adcom and the Bryston cannot deliver the current Kappa's need. If you drive them in extended mode, it switches off pretty fast. The Parasound and Vincent still work very well.


The Adcoms and Brystons are good amps, but they can't handle the low impedance the Kappa 9's will visit. I have two of them here for repair :-)
