XLR to RCA plugs or cable

I need to be able to plug the output from a phono stage in balanced mode (XLR plugs) into a single ended (RCA plugs) amp. My options are:

1. Buy Neutrik converter plugs (solid and good value)

2.  Buy Cardas converter plugs 6 times neutrik price

3. buy a custom XLR to rca cable?
