How To Properly Bi-Amp (Sonic Frontiers Line 2 to Two Amps to power Infinity Kappa 9's)

I recently purchased a pair of pristine Infinity Kappa 9's and I am looking to biamp them. I have a pair of Kappa 7's that are using a Behringer Europower EP4000 amp and it works great.  The Ep4000 cannot handle the 9's.

I am confused as to how to split the signal coming from my preamp for proper bi-amping. Do I just buy a split balanced or RCA cable? I feel like this would compromise the signal... Or do I use the additional outs on my preamp? My preamp is a Sonic Frontiers Line 2. I believe it has two stereo XLR outs and two RCA outs.

Please let me know.

...also, what is an powerful enough, extremely holographic, silky sweet amp for the mids and top section of the Kappa 9's? Suggestions would be greatly appreciated.

Thanks,
Brett

@brettmcee,

Use the multiple outputs of your preamp, that’s what they design for. In most cases, vertical biamping gives your the best possible results i.e. using one stereo amp per speaker. If you choose to use two seperate brand amps, external crossover is highly recommended as @cleeds pointed out.

If your amp has XLR inputs, I would recommend using XLR cables.

I am also bi-amping my speakers with a class D amp (ATI-543NC) for bass and a tube amp (ARC VT-80) for mid’s and high’s.
