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.
