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

Perhaps one of the Bel Canto integrateds......NEW.
Get the one with the USB DAC.

A PSAudion GCC series integrated of 100, 250 or 500 / side with something like a DACMagic. ??????? I guarantee the 250 watt ICE module'd GCC would work.

Is there any phase data on the Kappa 9?

I have HEARD that the EMIT / SEMIT type driver doesn't like distortion or overload. Is this true?

If true, I'd sell 'em and get pair of Cerwin Vega. If people are partying 'pretty loud' I doubt anyone is in the mood for nuanced presentation of 'the sounds'.
The Klipsh? Them too!

If the 'system' is now up and running, what exactly is wrong with it? Last amp die?
Others will hopefully chime in, but for a PARTY speaker, look no further than CV.
WTF, nobody is going to be sitting there, eyes closed, toe tapping to some incredible jazz performance. We're talkin' PARTY here.

I have ZERO idea about model, but one of the 'traditional' 12" 3-ways will get to to loud / party with a reasonable amp. Some of that bullet-resistant DJ stuff may work on the amp side.

For your 2500$ budget and the Kappas in trade, I'll bet I could get you Jailed or at least evicted.

Old / used amps, especially those which have been stored for a year or more may simply not put up with the kind of wacky abuse you may dish out. Or a friend with a little TOO much 'adult beverage' cranking up 'Stairway to Heaven' to hear it ALL!

I don't know about the Kappa9. Everyone here calls it an amp killer, so I'll lean that way, too. But nobody has remarked on what I thought the problem was....those pesky EMIT drivers and if the do or NOT have a problem at high levels with amp distortion......or maybe i'm thinking of the Heil AMT stuff?

Free speakers requiring a couple grand in amp, are probably not a big bargain!
Timlub, since apparently you know about the speakers in question, what is the phase data? While <1ohm is wacky and phase at that impedance is probably just academic, I'm curious now.

What does anybody do, or HOW does any manufacturer justify this kind of bizarre load? And SERIOUSLY, what good is it?

I believe in system synergy and all that good stuff, but buying speakers which require owning stock in the power company AND an EE degree to find compatible stuff is beyond me.
