Though I only tried the stock cable, I already agree with you that a "brighter" or higher "clarity" cable will make the 846 shine! I just got it yesterday and having listened to it a few hours, its mid and treble are a bit overwhelmed by the bass even I am only using the blue filter. Unlike the 1p2 I have, which I found the uber cable heighten the quality of the bass, the 846 needs its treble n mid heightened.
My friend just tried the Whiplash 8 conductor V3 TWag on the 846 n he said they match so well!!!
How does your 846 compare to the 1p2?
I am also a fan of silver. But I've always been- for the clarity it brings. A local DIY chap made me one at $100, a real steal since he also delivered it to me personally. :)
