Your opinion on cable spending

interconnects are more important in my system than speaker cables are

I doubt if there's a this OR that because it's all in the signal flow, right? Try to even out the quality (and the budget) by trusting your ears alone!
BTW: Kimber Select is one of the places to end up at! :-)
Good luck!

Generally, speaker cables are more expensive than interconnects, unless you have a system with very short speaker cables and very long interconnects.

Expect to spend more for the item which has the longer runs, which are typically the speaker cables.

Cabling is about synergy. This does not mean necessarily using all one brand. It means making connections which bring out the best in each component individually to get the most cohesive sonic presentation. Try out as many as your patience will allow. Many higher end audio dealers, along with the Cable Company (usedcable.com) have loaner programs. The Cable Company will also provide expert advice. Make sure you have a female pair of ears, they hear sounds different than men (sometimes they don't hear sounds at all). I have been through so many cables in search of the "right" sound, as many of us have. Here's my extra 2 cents; I find that smaller companies which have 1 or 2 levels of performance to be great values. They put all their energy into a design and then use the highest quality parts available. They're harder to find because little/no money goes into magazine marketing, thus prices stay reasonable. I will mention 2 companies I favor, not because they will be right ones for you, but
because they represent performance/dollar value: BEL and Dimarzio. It's possible you've never hear them or of them. There are others. I suggest you seek them out and compare them against the big boys (kimber, cardas, mit, transparent, etc). Happy hunting! Just my 4 cents.
