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

Not to be snarky, but a lot.  Vandersteen, Vortex Acoustics by Von Schweikert, Ascend Acoutics, Philharmonicaudio, magnepans with a subwoofer, and Salk Sound are a few that pop to mind immediately. There are dozens if not hundreds of options that will be easier to drive and sound as good, if not better.

What is your budget?  Adjusting for inflation would put them at about $4300 new today.  In that same price range, or lower:

Vandersteen 2CE Signature II- $2,700
Magnepan .7 ($1400) plus Rythmik F12 ($1000)-= $2400
Vortex Acoustics VR-33- $3,750
Revel F36- $2000
Philharmonic 3- $3500
Salk Sound Song 3a- $2995
Ascend Acoustics Sierra Tower- $1998

All the above are new prices.  Used you can get better deals or move up in the range (i.e. Vandersteen 3A Sig, Magnepan 1.7).  The above are just a few of the excellent choices available.  The 8s were IMHO, not anything amazing.  Pretty good sounding, but not fabulous.  You really have to spend some time listening to see what you like.  All of the above are great speakers, and there are dozens more.  The issue is what you like.  Some will like all on the list, some will some and hate others, some will hate them all.  It is very personal.
