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

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.

I copied this from Audio Review. I hope this helps.
He drives them with an Upper end Hafler.

I am still using them in my living room, in a stereo system, fed with a Hafler XL-600 or (alternatively) a Hafler 9500 Series THX Power Amplifier and a Classe CP-50 stereo preamplifier. Sources are: a Sony SCSD-XA777ES SACD/CD player and a VPI 19W Jr turntable with an Alphason HR-100 Tone Arm and an Ortofon Cartridge.

Hi Timlub-my previous comment was directed towards OP. IMO, he did not appreciate the "experience, suggestions, or words of wisdom", even though they were solicited.

Kind of surprising for a first time poster.

I think Bongiorno's Ampzilla would be a good candidate to drive those kappas.
More to discover
