Help power pair of Infinity Kappa 9's please

Hi all!
I have a pair of Infinity Kappa 9's:
Nominal Impedance: 4 to 6 ohm
Power Rating: 60-340 watts RMS
Efficiency: 102 dB SPL @1 watt, 1 meter
Crossover Frequencies: 80Hz, 800Hz, 4500Hz
Frequency Response: 29Hz-45kHz +/-3dB
Physical Attributes:
1x - SEMIT Supertweeter
1x - EMIT Tweeter
1x - 3" Edgewound Voice Coil Polydome Midrange Driver
1x - 5" Polypropylene/graphite Diaphram Polygraph
2x - 12" Cast Frame , L/C Tuned Woofers
Dimensions: 59.5"H x 21.5"W" x 8"D

My room is 12'x12', I have $2500 budget and would like to play music off my computer. I need amp(s), a preamp, and a DAC i guess (is the DAC necessary at my low of a budget range?). I know my budget is low so I will be shopping for very used/old equipment. If anyone has any experience, suggestions, or words of wisdom, they would be very much so appreciated.
Thanks,
JT

Sunfire receivers and amps are based on the technology of their forerunner, the Carver Lightstar Reference. They have a unique design to handle very difficult loads. Since Sunfire's are fairly common, maybe you can locate one on a trial basis. Be sure to get the most powerful one. If previously owned, they should be within your budget.

I also said you need to bi-amp the Kappa 9, meaning that you would need TWO pair of the monoblocs, two monoblocs per speaker. That would put you at $3k just for amps. You still need a preamp and a DAC. As I said, way above your budget.

Cajunpepe, yes, a single pair of Carver monoblocs won't get you optimum results, but two pair in a vertical biamp configuration is just the ticket.

If you like to party and play your music loud sell your Kappa 9s and buy Klipsch speakers.
