The most transparent speaker cable


Gentlemen, I've been trying already for three cables in my system and none has all of the qualities I'm looking for in one. Can anyone recommend me the speaker cable which will be the most transparent with best detailing, not harsh and not muddy with the deepest bass and beautiful transients?

I've tried Revelation Audio Labs, Oyaide FF-20 V2 and Russian noname solid core AC in-wall cable. Today I'm gonna test the AR solid core but I doubt it will win. What I like in solid core cables is that they giving me the best and coherent bass I heard but at a price of the transparency. Of all three, the most transparent however was the Russian noname solid core AC in-wall cable but it lacks the bass slam and finesse.
Some recommend me to try as a speaker cable the Mundorf MConnect Metallfolie...

I experimented with several DIY recipes - starting out with Temp Electric's recommendation and ended up with a single conductor per pole in untreated cotton sleeve. If you can handle the stiffness try dead soft fine silver round wire from riogrande (less expensive). I am now using AWG 6 gauge (SIX - no typo!) bare wire (no termination) in heavy untreated cotton rope. This is by far the most transparent and best speaker wire I ever had. Downside is that you may hear things from your system that you don't care too much for. But it will allow you to determine shortcommings of your components.
I am a big fan of Jena Labs cables. These are the most transparent I have ever heard.  Ultra pure copper in a strand-woven format with clear insulation... you will know exactly what you are getting because you can see it all.  The more expensive versions have more copper, which further reduces the coloration and electromagnetic field interactions with the floor and nearby components.
