How much do you want to spend? It doesn't do any good to suggest all these cables if you only want to spend a hundred bucks. The Kharma and Purist are in the thousands of dollar ranges.
I didn't see the Kimber Select line mentioned but it has exactly what your original post mentioned and its a good cable. Kimber has 3 levels in the line. I owned the second which is $1500 for 8ft pair. I bought them (used) for the same reason you mention above. Large, look like a snake, impressive hardware on the ends, especially the large aluminum knobs at each end. I got more comments from these than any other cable except the Magnan Signature....Magnan takes a different approach because it uses a very wide very flat ribbon. Each side has two runs, one per terminal (dah) and each are about 5 inches wide (literally). They are all black. The terminations are not impressive but the cable is impossible to ignore visually and will impress everyone. Kimber is more refined and manufactured looking where the Magnan looks more like it was made to order. I dont mean this in a bad way it is just more customized looking. The Magnan is only $1000 for a 8ft pair and to me they represent one of the real bargains in high end. I have heard them compared with Kimber Select (top of the line), Nordost SPM, Nordost Vahalla, Kharma, and XLO. I like them better than the Kimber and XLO, for most applications, and they are just a hair away from the SPM, Vah, and Kharma (but remember these cables are 4x-8x more expensive).
Just a note: the Kharma are big but no where near 5 inches in diameter. I dont even think they would get to 4 inches in circumference
.dont get me wrong, they are big but just not that big. Maybe 2 to 2 ½ inches in diameter, a little more than the Kimber but not much.
But based on your comments, unless you want to spend 3k-4k used, the Kimber is exactly what you want.
Happy hunting,
