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

Thanks for the input guys, I will look for some Mcintosh's and Carvers as well. What do y'all think about running the Kappa 9's with a pair of Krell MDA 300 Monoblocs?

Also Mitch4t I find pairs of Carver 9t monoblocks selling for approximately $1500 which you say makes your Kappa 9's sing yet is out of my $2500 budget. Please explain

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.
