Will the DNA125 or the Belles 150 be sufficient to drive the Kappas? I might be wrong, but with the Kappas, the MKI and perhaps the MKIIs, more watts with a large and powerful hi current supply is a must with the amp to be used. The higher the number gets in the Kappa sequence, the worser it gets.
Once I wrote an email back and forth about the possible strength of the DNA 225 and according to my recollection, the 225 is capable of driving ANY speaker out there, but then there were questions about the possibility of my speakers, the Kappa 9s, that dip to 1 ohm, whether the DNA 225 can handle that sort of load.
I might be wrong, but I would look at the Hi current design of both of the amps in question and go for the one which has the most robust power supply.
The Passion 400 supposedly will supply you with gobs of power, but it is very expensive.
The DNA 2 seems much more capable, but it all comes to what sort of music you listen to as well as the loudness you would expect from the amp.
