Hi! Folks generally seem to like Blue Jeans Cables for most things. I personally have a mixture of WireWorld Terra interconnects and a few inexpensive KabelDirekt RCA cables for connecting higher-powered equipment such as my Sonus Port and my headphone amp. They all seem to do the job just fine - the main difference I experience with the Terra interconnects is that they bind much more firmly than the cheaper cables, which is reassuring.
The Red River looks very nice, but is considerably out of my comfort zone, cable-wise.
@Mather might be your guy.
