I used to have Blue Jeans cable and interconnects and for the price I was generally satisfied. I then I bought some fairly basic QED cables for not that much more than what I paid for Blue Jeans, and there was a marked improvement in transparency and bass response.
I think for affordable mid-fi, Canare or Blue Jean may be OK, but for proper hi-fi, I think you probably have to look for something else better. OP specifies a budget of $500, so I guess his system probably closer to hi-fi than mid-fi.
