I have the original Homegrown silver coated copper braid unshielded which are a little bright. I've built Kevin Haskins version of the Risch Belden co-ax cross connect which were just OK. I see on his site that he has finished cross connect with Cardas Litz wire for $85. The only truly outstanding cable I have experience with is the 1985 vintage Straightwire I use from phono to pre-amp. It's thin and shielded so must be a small gauge and the RCA looks like all of that era, i.e. no gold, no silver no locking or other doo-dads.

Now if you want to talk speaker cable............
