Upgrade from Kimber D60?

I was looking for an upgrade from Kimber Kable's D60.
It seems lots of people saying that now D60 is obsolete, and many other cables which are less expensive or in same price range outperform D60.

So...I'm looking for suggestions.
I was searching for either new or used cables in price range of $150~$350,
and few candidates I've found are:

Stereovox VX2
Oyaide DR(DB)-510
Analysis Plus Digital Oval

Well...all above cables are actually cheaper than D60,
but I would be equally happy to spend more than I did on D60.

Thanks.
