Balanced vs. Single Ended Interconnects

From your experience, would you expect a higher quality single ended interconnect or an entry level balanced interconnect to sound better when connecting two balanced components?

More specifically, I will be connecting a Denafrips Ares ii to a Pathos Classic One Mkiii and I currently have Audioquest Sydney RCA interconnects.  Is it worth getting some cheap Monoprice XLR cables or should I just wait until I can justify purchasing something from Audioquest (probably Red River or Belden BAV) in the future.
