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...

Lot of good suggestions. I have some expensive cables but the Western Electric and Belden recommendation is one I can easily support. I have both 14 and 16 gauge WE speaker cables and think that both work well.
Where do you buy these?

No such thing as final anything in high end audio. I have got rid of all my expensive speaker cable ( MIT, High Diamond 8, Auditorium 23 and Nordost) and replaced them with cheap Western Electric 16 gauge speaker cable. $160 for 3 meter pair. Best I have ever heard. Really stunning cable. Also Belden 1804 interconects. $60 for 1 meter pair. Has all the qualities you want.
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.
