It appears that these networks are based around ganged zobels, but there very well could be more to it than this. And based on the end result I am getting here, I cannot say this is a bad thing.

Just use one speaker and put in your old setup of wires. For now, just pass on the biwiring aspect. Then attach one end of your DIY zobel to one terminal while the other is free. Assuming there's no electrical noise or audible sound, have the guy move his hand slightly to make electrical contact. Is there a difference?
Actually it doesn't. There's far less loss of signal with IC's than there is with speaker wire which is the primary reason if your preamp is a large distance from your amp, such as when you want to place the amp close to the speakers, you'll run long lengths of interconnects. You see this in audio shows all the time. This is usually not a problem unless your source has poor current drive capability. For folks using passive preamps then you should be sourcing low capacitance cables and even then you're constrained as to how long you can run them. What are you doing? You don't need to experiment if you know your setup unless you don't pay attention to the cable specifics.
Considering it costs under $10 to try and you can be sloppy with your soldering, why not? As to whether they're oscillating or not can't be determined by taking the amp out and testing it the usual way. If you read Pass' paper he talks about some of the reasons that occurs. It can be a system dependent thing. I'll guarantee you that you can make a Spectral oscillate and fry the SOB. But there are things you can look at to find if your amp might be prone to it. Is the distortion spec exceedingly low and the bandwidth exceeding high? It'll take you far more time and expense (time is worth something even if the service is free) to have the amp checked out 'in-situ' than it will for you to perform some basic tests/experiments at home.

I am not concerned about it oscillating anymore than anyone else in here is about their amp. Thank you for the info on how to check, I might try this on my old h/k reciever in my garage just for kicks.

Pass isn't over simplifying anything. Depending upon the amp Curl is talking about, there's a good reason to like a network the thing is, you can implement one for the price of a couple of cups of boutique coffee or a mixed drink.

Honestly, I am satisfied with my cable decision for now. When I decide to upgrade my speakers, I will be looking at cabling again.
Once again, my passive pre is an integrated amplifier, so no long runs of IC's. As much as I would like to locate my system rack off to the side of the room, it isn't feasible in my situation.

You have a PM.
Your comments on how it sounds would be speculation of course.
