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

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.

Although some folks do get on here & brag about their gear, that's not what it's really all about. If that's your goal, I think you're going to be disappointed when you ask for advice, especially when you retort with, "thanks for your discouragement" and "Lets turn this into a naysayer-free zone plz".

Am I reading you correctly?

I agree, lets keep this a neysayer free zone. I don't know that the comment from Driver was even meant toward me, but Nothing should be discouraging about quoting a fact. I do not own an Andromeda, I used to sell them years ago. The discouragement would be giving incorrect information. We should always try to distinguish fact from opinion.
Again, in my Opinion, not a good choice for these speakers. I really recommend to replace them if good amplification cannot be afforded.
