Digital Cable Recommendatoins

I was using a Moray James digital cable with my Museatex BiDat. In the past I had the Acoustic Zen digital cables and a few others in the used price range of $300 or so but the Moray James was a better sounding cable in my system. I remember reading about other cables the Stealth and how others found a cable they eventually preferred for less. I finally built my own DAC 32 bit with direct heated triode tube design, so I am thinking about trying other digital cables in the $600 price range to see if they will improve the sound. So I am looking for some suggestions.

Thank you in advance and Happy Listening.
