At the risk of opening a can of worms, I'm wondering what people are using to wire from NC400 module to speaker terminals? Wire gauge? Solid conductors? Stranded? Do you consider it critical? Am I splitting hairs?I searched but perhaps wasn't using correct keywords. Gotta be other assemblers wondering same thing.
The way you actually use the wire is much more important. Make sure it is twisted properly, especially at the nc400 end (a lot of people seem to get the exit direction of the wire wrong at the screw terminals).
Thanks for the input, Julf. I've read a bit on wire orientation. Both wires exiting terminals towards nearest edge of module...correct?
I use 4mm stranded wire. As long as the wire has low inductance and resistance and can carry the required current, the actual wire doesn't matter much - stay away from exotic stuff like litz wire.

I used Cardas litz wire for both power and speakers with excellent results but it is difficult to work with. I stole the idea from the 10k Veritas NC1200 build, I believe they did lots of testing finding the Cardas to synergize best.
Litz wire is a good idea when you want to minimize transmission loss due to skin effect for moderately high frequencies (100 kHz-1MHz), but it does not really make sense for normal AC cables or audio frequencies.
Julf, out of curiosity, is the 4mm wire you're using the conductor size or overall wire diameter?
I changed the input wires to the NC-400 from the wire provided (each about 6 inches long in my build) to a 22 ga. shielded silver clad copper/teflon wire (Signal Cables) and it is quite a difference. Right off the bat, clarity and detail presentation is notably improved, bass is clearer and tighter, but just as powerful and deep.
I guess I should start selling expensive audiophile molex connectors....
Does anyone know the Mouser parts # for 12 pin molex connector used from SMPS 600 to amp?
