noob question
 

hi everyone, I got a question about my what I should buy. I already have a CD5000 hu, and 2 old school soundstream amp and I looking for some speaker, I hesitate btw kappa 692,7i with kappa perfect 10'' and kappa perfect 6.5 component. My other choice would be to go with nakamichi stuff (they're 6x9,10''sub and probably 6.5 to the front. what do you think would sound better? (a mix of both, only nak or infinity ??) also I often listen blue man group, van halen,techno, well almost everything.
thank you!!
