After looking more at the websites for Kimber Kable and Morrow Audio, I think I'll most likely stick with Audioquest if I purchase another set of interconnects.
The Kimber Kable interconnects in my price range look to be three wires braided plus interconnects.
The Morrow Audio interconnects appear to be multiple strands of small gage wires running in parallel.
I'm not knocking either product, but I'm not sure how either of these configurations could provide much shielding (something that's important to me in my setup) in a single ended interconnect. The Kimber Kable configuration would be expected to work great in a balanced interconnect.
