A lot will depend on the overall balance of your system. That said, I might try the Belden 8402. It "may" be have a bit more warmth. Lots of good choices whether you DIY or order from one of the pro outfits, Ebay or even Amazon. DIY gives you more flexibility in regard to the the RCA connectors you use, but it seems some sellers at least offer Switchcraft RCA's. In the end, both are good choices with no real way to determine how either would work best in your particular system.
