You sound like me - you want it all.

I think that the trick will be to get a cable that sounds full and has a nice mid along with the other attributes you mentioned. The stereotypical sound of silver cables wouldn't do it for you.
That said, one IC that I feel does it all is mde by Slinkylinks (
www.slinkylinks.net). It uses 4 pure silver wires encased in an air dielectic (theoretically, the best dielectric is air, followed by teflon). I compared it against several IC (silver, copper, hybrids) in my system and a friend's and we thought it managed to do it all, plus provide great musicality. I use this IC from my source to my pre. I also use their speaker cables. The prices have gone up since the NZ$ has appreciated a lot in the last 2 years, but see if you can score a used pair.
I used to have the Kimber KCAG. My system was very different back then but it seemed to sound a little bit thin and seemed to call attention to any upstream problems in the HF.
I also really like Bolder Cables. I use their Nitro IC (silver / copper in a teflon dielectric) from my pre to amp. There are numerous comparisons posted here and on
www.harmonicdiscord.com about this excellent cable. It is much cheaper than the Kimber KCAG but really sounds good. Its been used in Brian Cheney's (of VMPS) show-winning system. There should be a few of them floating around used since its been around for a couple of years. The cryo versions are a bit better but I myself use a non-cryo version. Wayne is on the verge of launching a successor to the Nitro (which is his flagship IC) so more used Nitros may be for sale.
Wayne's M-80 IC has much of the performance of the Nitro but for much less. It will fit very well in your budget brand new. I use the M-80 from my dvd player to tv and also from my pre to my sub. You can also find comparisons of the M80 to the Nitro here on AC. There are several people here who use M80 ICs and speaker cables with very very expensive gear.
Jason (Pez) and Tyson have done several cable shootouts and posted writeups here on AC. They've used some of the cables on your list.
Have fun!
