Help me power my Kappa 8.1's please!

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.

@tls49. Thanks, can you tell me more about going dual mono block setup?  Would i still need an integrated
amp?  

I have two inputs - one from computer via dragon fly red dac and one from TT via tube preamp...

Given your budget, you will need to get an integrated amp. Forget dual monos unless you plan to spend multiple thousands. And just so you know,

An integrated amp is a combination of a basic preamp and power amp. If you used a stereo power amp or dual mono amps, then you would also need a basic preamp.

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.

Here's a good read...  https://www.qacoustics.co.uk/blog/2016/06/08/bi-wiring-speakers-exploration-benefits/

I already have bi-wire speaker cables.  If nothing else, it's less resistance.  But I do hear a difference.  It's subtle.  

I noticed a much bigger difference when I wired my speakers in parallel (ch A to High Fr and ch B to Low Fr) on each speaker.  I did this with my cheap Sony 2 channel amp (100W per channel @ 8ohm) and ran A+B at moderate volume levels for a month or so before someone told me I was crazy to do that and so I stopped and went back to bi-wire.  Its a cheap amp though and it sounded WAY better so I'm thinking about doing it again!  There was more separation, and energy, especially through the midrange.  I don't know the internals of this specific amp but it made everything sound better.

This is why I want to bi-amp these speakers if I'm going to spend money on an upgrade...
