Bulk power cables suggestions

Thank you all for your replies and sorry for the delay, the notifications seem not to be working.
I’m sure industrial cables are a good bet and I’m very humble about my DIY skills (@williewonka I know your site and intend to try your recipe :p). I will buy industrial cables and have fun with some DIY on the side :) at the same time.
Thing is, there seem to be a handbrake in my system, and I would like to upgrade its power delivery with good wire and connectors to form a base of comparison for later upgrades and find which components to focus on.
Bulk wire from Furu, Oyaide, .... seems to be a good place to start and I’m looking for some people’s experience on them.
Maybe the conclusion is to buy some old reference cables used as it is cheaper in the end, but some first hand experience would be appreciated :)
Thanks guys

Thank you guys, so many suggestions.
I will look into all of them.
Millercarbon has a point, but I find it fun to peruse connectors, recipes ans tweaks for PCs, I don't know. I will buy manufacturers cables as well. One approach does not exclude the other.
There is DIY and DIY. I guess making a cable from scratch implies a lot of trials and costly errors for an incertain result in the end, but choosing bulk cables and connectors can perhaps ensure a certain level of quality at a fair price, even if not as good as renowned products. 
Anyway thanks for your inputs, it is/would be great to have some real world testimonials about manufacturers bulk cables !

Hello all, and thank you for all the replies!

@petg60: yes, I don't want to skip on the plugs, I'm convinced of their importance
@auxinput: thanks for the feedback on Wattgate
@discopants: this Oyaide has a good reputation and is on my short list :)
@hdm : I'll have a look at their offering, but was not sure at first, as there chinese (I don't have a problem with that) passing themselves for a german brand (I have a problem with that)
@tantejuut: thanks I will think about it
@williewonka : as I said, I'm really interested in the helix approach and will try it definitely, and compare with a bulk wire of my choice.

I've gotten good hints from you about the advisable diameter, the importance of the plugs (thinking FI-E35 or 38). I have then to chose between the Ramm Amadeus 5 MKII, the Oyaide Black Mamba 2, the Furutech FP-TCS21 or FP-S022N (preamp and streamer) and the FP-TCS31 or FP-S032N (amp) :D
