Suggestions for a digital cable.

My only experience with digital cables are the ones I own, which I like and most likely will stick with. I have the Illuminations D60 from streamer to DDC and the Orchid XLR from CD transport to DDC. I am in the process of evaluating adding a Mini DSP SHD Studio to the system which will go between the Digital sources and the DDC/DAC combo. I have the choice of SPDIF or AESEBU. I am leaning toward another D 60 here. (Far less money than another ORCHID) and willing to look at used connectors for $400 or less. Anything I should look into that would equal to or better than the D 60 for the price? I have a lot of History the the two I have. Thank you! If this matters as well my analogue cabling is Wireworld Eclipse 8 through out and Silversmith Fidelous speaker cabling.
