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

You need amps with more testicular fortitude.

Those Kenwoods have alot of power, 300 for the L09 and 150 for the L07, but they will not produce the current needed to drive the Kappas.
New amp or new speakers, or listen at low levels.
Back to Jtiesel... I believe the Coda amps will drive these quite well and are nice sounding amps. Call Doug @ Coda, they will shoot you straight. Tim

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.
