I like Audioquest very much. One of the things I like about them is that you don't have to spend a lot of money to get a nice difference in SQ. Personally, I find that it is not always the case with other brands. Given what you are looking for per your post, I would stick with AQ. I think you would prefer a solid core copper cable over stranded copper. (Generally speaking; I'm sure that there will be some exceptions).
Stevecham recommends Mapleshade. I know very little about them, but I have seen several comments from people that use them and they were all very positive.
