    any of those will do fine. I havent heard much of a difference in SQ throughout amps, except the JBL sounds a little dirty. However, none of those are real cheap amps so in my opinion you will be fine with either of them. If its all the same price, why not get the one with most power, especially since it is ED and they are very well known for quality. However, I know the Punch HX2 is 500 RMS, what is the Kappa??
