Neutral Sounding Silver Cables?


I'm looking for a new/used xlr cable to go between my Aesthetix Calypso preamp and my recently acquired Aesthetix Atlas amp. Aestetix recommends Kubala Sosna cables....and I'd love to get a pair of used Emotions, but they're a bit out of my price range for now. I'm guessing that the Kubala Sosna Emotion is a relatively neutral cable...so I've been doing some research on used cables and am looking for something less than 1k in the used market. I couple of cables sparked my interest: Siltech 550i or 770i as well as the Kimber Select 1130. Both of these cables incorporate silver. Any comments regarding these two cables? Any suggestions for cables with some silver that are neutral with bass response?

Acoustic Zen Absolute is silver with 1% copper in oversized foam Teflon tubes. Very neutral cable. I got 0.5m XLR for $600 used perhaps because of uncommon length. On the other hand 2x shorter cable is 2x better cable.
I have that same set up running vandersteen sevens. I am using kimber select silver. I find them kind of harsh and overly bright in my set up. Now when I was using quicksilver v4 and vandersteen 5a it was a well matched cable. I just thing the atlas is so much faster than my old amps also pairing a faster speaker the silver got twangy, at least the kimber, copper might be better or a different silver cable. In any case I would try to demo something. I don't know if this helps but it is what I think of in my set up. Ymmv.
