In terms of sound quality the stock focal cable better than other cheaper cables I've tested.You might be the first person I've ever heard call a stock Focal cable "good" (let alone, "quite good"). I mean, they're not as bad as some of the stock Hifiman cables, but for me and most others, the Focal cables are stiff and microphonic AF. Borderline unusable, especially for headphones in their price range.
What you describe sounds to me like the very definition of "subjective." If you were to try six different donuts back-to-back and then say the jelly donut is better than the other five, that is a subjective preference, not an objective one. As for me, I'm not a fan of silver cables for any audio application, and I know many others who feel the same. In my experience, silver cables screw with sound quality in unpredictable ways. But, of course, that's just my own subjective preference (as is yours).
Totally. If you're looking in the price range of that Tripowin (~$50), you can find a bunch of budget options in the cheap cable thread.
Not saying its great, like you said its microphonic and unwieldy.
The silver dragon cables are not actually pure silver, they're spc. I would say my wywires platinum cable is better overall than the silver dragon, this my objective opinion but I prefer the silver dragon because it gives me more body and thickness to the sound, that would be subjective preference.
I find that if its good quality pure silver and good quality connectors, its better and I know many others who feel the same as well. But good quality silver is very expensive and difficult to come by.
