best cables for simaudio xlr balanced

Looking to use balanced xlr cables for my sim pre p-5 to my power amp w-5. Any suggestions, would like to spend as little as possible, but want a cable that will help get the most out of my system, I don't want to skimp but also don't want to overpay. As for the rest of the system: VPI TT, ear phono stage, and My speakers merlin and apogee ribbon tweeter tweek driven together. By the way I just recently mounted the apogees tweeters to a frame next to my merlins which are suspended from the ceiling , both the merlins and the apogees are suspended by cables from the ceiling. So far I am very pleased with what I am hearing from this unusual combo. I know it sounds crazy but if you knew me you would have expected it.ha ha. Again just to make sure it's understood, I am using the merlins (both drivers: tweeter and midrange/bass driven as designed to) and an apogee tweeter ribbon from centaur.
