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 have the Kappa 7's and the Kappa 9's. I have the K7's matched with a Levinson No.23 amp, great combo for my room size (17 by 25ish).
The K9's need a much bigger room and 600 watts per chanel or more to truly apreciate them. I would prefer McIntosh MC1201 mono blocks or as others have stated, bi-amp them.............in either case, my opinion of the K9's is that I love the sound that they are capeable of. You just need the room and the budget to let them do what they were designed to do.
If you feel that the K9's are increddible speaks, then you have to commit some fundage to them and you will not be dissapointed.....otherwise sell me your parts because I intend on keeping mine for as long as I can!
