Help me power my Kappa 8.1's please!

I would like to Bi-amp these.  

Budget is a real thing (I just dropped about 3500 getting into vinyl)  I'm hoping to spend between 500-1000.

I would consider Vintage gear, but I despise spring clips.  I would prefer something NEW, but am open minded.  Has to look nice.  Blue lights a plus!  Can't I just have everything I want already lol!

Infinity Kappa 8.1
6 ohms
40-300 watts RMS
89dB 2.8V/1 meter 

I've been looking at modern integrated's but the low impedance has me confused about what will be compatible...

Thanks and Happy Friday!

No, those speakers need serious power. There's some amps available at less than 100wpc that could drive that speaker properly, however they cost well beyond your budget. Save up more money so you can buy an adequate amp. Also, you could get more amp buying used. Something like this,

I just read a review of the Anthem on digitaltrends and if it sounds as good as they make it sound then I WANT ONE!  

With that much power, Bi-wiring should sound great right?  I was thinking Bi-amp but this would simplify things.
As one member here said, "Bi-wiring may or may not make a difference, and if it makes a difference, it may or may not be better." Some speakers have actually been designed for Bi-wiring, but for the majority, it's just "audio fashion." Bi-amping done properly means you would need to bypass the speaker's internal crossover and use an external crossover. Keep it simple with one quality amp and a single run of speaker cable, you'll have less headaches and more enjoyment.

i have kappa 8 alsoi am running denon poa 2800bi amping will positively change your view of your speakers and bring them to lifethese speakers are power hogs and need all they can get
Yes, the speakers are power hogs, however it will be best to have that power in one amp. Bi-amping is more complex than just using two amps. As I said, it is best to use an external crossover. The only arrangement that can work OK without an external crossover is a vertical bi-amp with two identical amps, however it would still be better to have the same power in one stereo amp or two monoblock amps.
