I used to have the Kimber Silver Streak. It lacked the dynamics of most other interconnects, and was somewhat soft with transient attack. The treble was a little rolled off, and the midrange was a little noisy; bass also lacked extension, slam, and pitch definition. I've not heard KCAG. An acquaintance of mine sold his $2000 Kimber Select interconnect, and thought the HT Silway was better (it might be, I don't know). Many reviewers are running around like rabid goats touting the Silway, it's pretty funny to watch. I've tried it against the following interconnects directly, and stand by my assertion that it is very laid back in the midrange (that doesn't mean it won't be great in the right context, though)...also several manufacturers I've spoken with feel the same way about it, so what I've heard isn't an anomaly, IMHO: Straight Wire Solo, AudioQuest Quartz, AudioTruth Lapis and Diamond, Cardas Neutral Reference, Tranparent Ultra, Transparent Reference (new version), MIT 330 Shotgun, MIT 350 Reference, and MIT 350 Shotgun EVO (easily the best in the world). Two more that I'd like to try are Straightwire Crescendo and the new Cardas Golden Reference. I don't expect either to measure up to the EVO, though. And I got it used for only $795 ($3100), so it is just amazing!!
