I’ve done a lot of R&D work with power cables. In your short list, I would probably choose the Neotech NEP 3200 because it uses solid-core conductors. In all my testing, I achieved the best results with solid core. That being said, this particular cable uses 17awg solid-core conductors. These may be a little bit large for the sweet spot I have found (which is 20awg conductors). The larger awg conductors (16-18awg) will have rolloff in the high frequencies. Because of this, I would choose rhodium plated connectors for the terminations to give you the best amount of high frequency resolution.
On the terminations, I would actually choose Furutech as the best terminations (both in build quality and design). The FI-28 series is a very nice termination. Furutech actually connects all the case mounting screws as well as the internal cable strain-relief clamp to the ground conductor. This does add additional cost, but I see it as a small positive. The Neotech terminations do not have grounded case screws. I don’t think you need to go with the FI-50 series unless your splitting hairs and willing to spend the $$$. The Furutech FI-11 series is cheaper, but it uses phosphor bronze for the IEC and case/strain-relief screws are not grounded. The newer FI-15 Plus series are nice, but keep in mind the FI-15 does not support thicker cables (the Neotech cable above would be too thick).
I have used the previous generation Neotech rhodium connectors. These were not that great and tended to push too hard on the voltage. The Furutech connectors above are much better and much more "delicate" with the sound - at the same time giving you a lot of resolution and punch.
