Redling,
Running aktiv, your Espeks need three channels of amplification and three pairs of speaker cables running to each one because they are three way speakers. Your Ekwal is a two way speaker, and therefore requires two channels of amplification and two pairs of speaker cables to it. You can run the Keilidhs passively biwired, but as you already know, this requires two pairs of cables to each speaker also.
You should understand that the aktiv cards do not make a Linn system aktiv by themselves. You must have a channel of amplification and a pair of wires running to each driver in each speaker. For the Espeks, consider Linn K600, a six wire cable, and for the Ekwal, use the Linn K400, a four wire speaker cable. I have used them in the past, and they are extremely good-sounding, but not visually beautiful, cables. Consider the K400 for passively biwiring your rear speakers with the LK85s. I had a very similar system in the past. There are no other cables that I can think of that will will compete with them for the price.
As your rear speakers are so far from the rest of the system, consider placing the LK85s in the rear of the room and use longer interconnects.
Good luck with your system. The sound of an aktiv Linn system is truly world-class.
