If you look at the impedance graph, you will see peaks, they are shaped by the reactive(capacitance, inductance) parts in the drivers that we call resonance points.
If you look at the top graph, impedance is flat, which means it's pretty much resistive, which means capacitance or inductance is very negligible. What you are seeing with the bottom two graphs which is power transferred to the load(the NT6) through the cable. Since the cable's impedance dips down as low as 8ohms at the treble frequency, if 2.4 ohms cable is used, you will lose more than 20% of power transfer, which will translate to less treble output. Why this is significant is, if you look at the graph, some frequencies has barely any loss because compared to the impedance value at the frequency, it's negligible, but at the treble it's enough to drop 20% of power. So therefore, FR will change with the 2.4ohm cable.
Given what I see from Rin's graphs, I would have to conclude, it's basically adding small amount of resistance between the output of the source and the headphone. I will have to conclude that the Whiplash cable is nothing more than resistance added to the system. Curious what the value is?
shwl: Nordost 7N, OCC-7N silver-plated
rubin: Hidition old stock, Hidition new stock, 5N copper, DIYer(fate)'s flourescent cable, Nordost 7N
udauda(Rin): $20 Furutech cable from Ebay, Ultimate Ears stock
My friends have sent me seven cables for this analysis, and my two cables are added to the pot. As expected, the OCC-7N silver plated cable and the Ebay furutech have the highest conductance, while rubin's Nortost 7N performs worse than others, indicating my friend rubin has been completely scammed.
And the actual electrical conductivity of each cable goes like this:
OCC-7N > Furutech > UE stock > shwl's Nordost 7N > New Hidition stock > 5N > Old Hidition stock > Fate's DIY flourescent cable > rubin's Nordost 7N
