Amp or amps to power a pr of Kappa 9's & Kappa 8's

While not familiar w/Kappa speakers I am familiar w/Parasound amps. Specifically a Parasound HCA2205 is a classic amplifier many home theater specialist like to use when setting up a home theater system. It is a five channel amp rated @ 220 per channel, all channels driven that increases in wattage output as system requires @4 and then 2 ohm. Great bang for the buck, built like a tank approx. 95 lbs.

What is your budget? What are you using now.
I own Aragon Palladium 1k monoblocs. They may represent most high endish real watts per dollar in a big amp. I personally have subjected them to 4 ohm loads with 90db/W/M speakers. They never ran out of steam with any speaker I own but all are efficient. They have sets of binding posts and are stable to 2 ohms I think possibly 1 ohm. I have heard them cruise beautifully with much more punishing loads like big Magnepans.
A good friend is a speaker repair guru who specializes in older Infinty. I have heard the Kappa 9s with moderate power and agree it's not pretty. They do need juice.
They are 400wpc into 8 ohms and will produce 1K watts at 2 ohm, thus the name aragon 1K.
The Carvers aren't as sophisticated and don't have the detail retieval. The Carver's always reminded me of pro audio sound. That said if you are selective a few Carvers have been given good grades. The silver 9Ts are supposed to be good but many find them little different than the usual carver signature sound. The name of the one to get was a limited edition model XXXXstar. I can't remember the whole name right this second.

I like the sound of my Kappa 9s with the ARC D400 Mk. II. Be warned, however, because that amp clocks in at about 75 lbs. It is a monster, just what the Kappa's need.
