which brand cable should i consider too?
Lobster king- One of the nice things about purchasing pre-owned Kimber products is that they are easily sold for what you've got in them, in the unlikely event that you don't like them. Based on what you claimed as your prerequisites, I believe you will be more than pleased with the 1130. I'm extremely finicky(probably anal) about transparency, all the same things you sited, and wouldn't think of trading out my 1130's. Matter of fact, here's a pair for sale close to your price range; (http://www.audiogon.com/cgi-bin/cls.pl?cablintr&1226204450&/Kimber-ks1130-xlr-1-meter-pair) I'll bet they'd take a grand.
I don't know if anyone has heard the KS-1136 (XLR) but they offer the same airyness and detail without any brightness or harshness plus they offer a tad more bass and it it tighter. I've had both and sold the Sky.
Of course, some of the differences heard or what is better is system dependent.
The KS-1136 offers two silver positive conductors and two silver return conductors. The KS-1130 uses one of each.
