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

I to have some questions about the Kappa 9's.
A friend gave me a pair to demo. I have them Bi-amped
with Kenwood L-09's (300watts@8 400@4 & 1000 Dynamic@4) and L-07 monoblocks. This seems OK great sound but the the 9's will clip a half volume. (dims the lights as well!). I have turned the gain all the way down and that helps. Thinking I may just give these back and move on. Any thoughts on the kennys

Thanks,
I will be moving on, No Kappas in the house .
While I am sure they sound great with the right amps
there just not worth it for me.

Thanks for your input.
