inexpensive xlr vs expensive rca

I currently use homemade Belden 8423/Neutrik XLR throughout my system. Mainly because I was spending money on getting all of the components up to spec.

I'm looking at some used, very high-end RCA cables at a good price. I can't find the equivalent XLR cables used, but I can find XLR cables a few levels down of the manufacturer. For instance, $1500 RCA cables for $600. Or $700 XLR cables for $700. 

I'm connecting a Parasound JC-3+ and an Ayre QB-9 DSD to a Parasound JC-2. All first-class equipment. 

Would I be better off getting the super quality RCA used cables, or the less high quality (but still good) brand-new XLR cables at the same price point?

If the preamp and amp support the balanced line standard, then you'll be fine running the less expensive balanced cables.

The balanced line standard was devised to reduce the sonic issues of the cable. Originally it was for trans- and inter- continental phone calls, which it made possible because the signal degradation is so much less than with single ended. Contrary to popular myth, the length of the cable is irrelevant- you can still have a benefit if the cable is only six inches.

Check with Ayre and see if the preamp supports 'AES file 48' which is the balanced standard. If yes, you're good to go.
