Power Cable DIY - Please advise

I want to build a really high-end DIY power cable for my two large monos (Electrocompaniet AW600). I have the Furutech DPS4.1 with Furutech FI-50/52 NCF (R) plugs to feed my mains filter. Wall socket is Furutech FT-SWS NCF (Rhodium). Feeding the whole chain like this gave a really tremendous push towards resolution. Especially big orchestra and especially choir pieces are now much better than before. Regarding Rhodium there is a lot discussion regarding sounding too bright or sharpness in sound. I got a really great advice from a dealer. He suggests to always start with Rhodium from the power source, i.e. first the wall socket, then the cable from the socket to the filter/multiple socket, then the cables for other components. I did that and it actually worked well this way. I even changed the sockets in my mains filter to Furutech NCF Rhodium (Lab12 Gordian, IEC male inlet, Schuko female outlets), which again improved the sound in the same direction.

"All my power cable is hand made. I use 20awg solid-core OCC copper conductors with Teflon coating (the Neotech chassis wire) for my power cords. Each power cord has eighteen 20awg conductors -- 6 conductors per leg (hot/neutral/ground). I braid all the conductors -- each braid has a hot/neutral/ground, so that makes 6 braids for a power cable, making it a 12awg power cable in total."

For the power amps, the DPS4.1 is a little too expensive for me (I need 3m). One of my favorites would be the Neotech FP-3200, but then I read about your DIY mains cable using braided Neotech 20AWG solid core, which sounds very exciting.

Would you mind to tell a little more about it (or do you sell them commercially)? How tight did you braid the hot/neutral/ground triplets? How did you put together the 6 braids to form the whole cable (braid again, twist)? The Neotech 3200 is built around a core (fiber filled PVC), did you do similarly? A photo would be awesome. How much wire do you need to get 1m of final braided cable? How would you compare the sound of your cable with the Neotech FP-3200?Sorry for the many questions. I really would like to build this cable, because I think this would fit my amps perfectly. Electrocompaniet suggests to use unshielded power cable for them. In terms of plugs, I would use Rhodium plated, either the Neotech ones or the Furutech FI-28/38. Again, the FI50/52 are too costly.

The Furutech DPS4.1 is supposed to be a really good sounding power chord.  I have other Furutech power cords here that I use and like but have not heard the DPS4.1.  One consideration is that for power amplifiers I typically like the largest gauge chord I can use and have tried as large as 7awg on my power-hungry amplifiers. 
The Furutech DPS4.1 is an 11awg sized cord and the materials and construction are different from the Neotech NEP3200 (you indicated "FP" but I believe you meant "NEP").  The Neotech cord is larger (9awg) and is one of the few cords that are actually made from individually insulated solid core wire.  Solid core wire is typically not recommended for power cords due to the higher risk of failure (compared to stranded wire) when the cord is subjected to repeated bending.  However, the Neotech cord gets around that by using multiple, smaller, individually insulated wires.  It is also highly rated by listeners and would probably be my choice for power amplifiers compared to the DPS4.1.
Regarding DIY power cords, I prefer to terminate premanufactured cable vs. using hook-up wire to make cords.  I have done it both ways and for safety and uniformity (i.e., evenly spaced geometry) I like using the premanufactured cable.
Regarding Rhodium connectors, you basically need to listen and decide what you like.  Furutech connectors are typically awesome and as good or better than what you get on most manufactured cables.  The thing about Furutech connectors is that the base metal is typically copper so the plating IME makes more of a subtle sonic flavoring than a wholesale change.

I don't sell commercially.  For the 20awg, I took one hot, one neutral and one ground and did a tight braid all the way down (looks like a kimber cable).  Then repeat for each additional combination of hot/netrual/ground.

That being said, I don't know that I can officially "recommend" this design.  This design does not meet UL requirements because it's basically hookup cable external that is doing high voltage. 

My current recommendation for any DIY is to buy a used Audioquest NRG-4 cable and then chop/terminate with Furutech rhodium connectors.  The NRG-4 is the best cable I have found that has properly sized solid-core copper conductors.  It's their "perfect surface copper" which is close to OCC.  The NRG-4 is only 13awg, so it might be light for a very high power amp.  You can try doubling up or get one of the latest Audioquest high-current cables.
