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

how about some of the wyredforsound stuff

Class D & some say it sounds great. I talked tote them a while ago about how to power my kappa 8.1's & also a pair of 18in subs I was thinking of building & they stated they sell their amp for pro audio stuff to power sub's

I have been wanting to try a pair of 9.1's however my present amps aren't enough for my 8.1's so I need to wait. I started with a Adcom GFA-5500 & after getting married I switched to my now wife's amps, parasound HCA-1500a's. They sound a LOT better then my Adcom ever did especially when I bi-amp the speakers but I do not have enough amps due to needing them for the HT setup. So I think I will try the larger of the wyredforsound amps, probably try a multichannel amp so I can do 500x7 but due to money reasons, start 500x2. Then hopefully use that single chassis to bi amp my present speakers as well as power the surround speakers.

I thought somewhere there was a writeup on how to change the wiring on the 9's to eliminate the low ohm dip they take.
