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

Alright, Alright, I'm gonna listen to you guys (not attempt to power these Kappa 9's for $2500), no matter how harsh you make it seem. But I already have a home theater system consisting of some infinity's and JBL's and a decent Denon amplifier so I'm not gonna spend my budget on new audio equipment. I actually inherited the Kappa's about 7 years ago so they can stay in storage for some more time until I'm out of school when I'll get them running and get back on here and brag about how incredible they sound. Until then thanks for your discouragement, j/k =D

Oh Minorl, totally! I was thinkin bout starting with a pair of Krell MDA 300 Mono's, keeping the Kappa settings to "normal" mode (as opposed to "extended"), not gettin crazy with the volume, and workin my way up from there! Thanks for the good idea with using the CD player too! Lets turn this into a naysayer-free zone plz!

Jtiesel2, if you can store them until you are ready to power them with sufficient amps,you will be greatly rewarded by their sound. When powered correctly and matched with an excellent preamp and source, they are sublime. I own four pair of them. Hang on to yours, you won't be disappointed.

You may want to look at some of the professional gear for the Kappas.
Pro amps run 2ohm loads all day long for years, I don't think the Kappas are going to provide a problem.
You may be suprised at the sound quality of some of the better amps on the market, and they should be within your budget.

May be a viable option with some research.

As I said before the Original Sumo Andromeda is not a great match
Sonically, but you are flat wrong the about
The a Andromeda being able to drive them.
I don't mind any difference of opinion, but
In this case it is fact, I've seen it done.
More to discover
