you haven't said what your budget is, but I gather from your post you's shooting for closer to $500 than to $1000. I'm sure others can be more helpful than I but you'll want to specify this.
I'm not familiar with the Kappa9's, although I have a pair of B&M M200 Sonata's which I bought from a guy who was using them to drive Kappa's. I would think the M200's are a good choice for them. Do you know which B&K Model Amps he was using (ie that he burned up)? M200s are very stable to low impedance (ie <2ohms), and they can be found for <$600, and sometimes <$500 for a pair.
Further, I'm not familiar with the Parasound HCA 1200's either, but I have owned HCA1000's, HCA1203, HCA1205, and HCA2200. I prefer the B&K M200 Sonata's to all of them. The HCA2200 is the only one of them that is close to the M200s, but I sold my HCA2200 because I prefer the M200s. I still think the HCA2200 is a great amp and would also be a good choice for the Kappas. You can probably find one for $650 or so.
