Hello can anyone please tell me what the included cable lengths are that come with the NC400/SMPS600 kits? Specifically, I'm interested in knowing how long the cable bundle is that connects the SMPS600 to the Amp Module as well as the Mains cable that connects to the SMPS from the IEC Input.
By my rough guesstimation the SMPS to Amp cable bundle looks to be about 8.5" long (end to end)? Not sure why this info isn't listed in any of the documentation anywhere. 
Since we are dealing with pre-terminated bundles I think this is a key piece of information to know while in the enclosure sizing and component layout phase of a build.
Also, has anyone "Shortened" the 12 wire bundle that connects the SMPS to the Amp or is that considered a No, No?
Thanks
The specs are misleading. The length varies with twists (mandatory) plus required bend between the components. The tighter the twists the less can the wire be bent, which affects maximum spacing.
The only positive thing to do is buy the kit, twist the wires, and connect both ends. Then you can determine appropriate maximum spacing of components. It's a package deal and you can't figure out the limits on paper, period, end of report, it's impossible. IOW, if you need to ask the question, the answer is misleading. I had kit in hand when designing the Siliconray chassis by my name.
Why would someone design a chassis layout without the parts in hand? There is no known reason to do that. It makes no sense, with all due respect.
1. Buy parts
2. After parts arrive, twist cord, plug cord on both ends, design amp layout
If you design a layout without the parts in your hands, and you cut holes, and the parts fit later, either:
you could have increased spacing between the amp and ps, which improves performance, or...
you are insanely lucky
There is no other alternative.
