, BTW , a cable should have came with your preamp? On Church's ebay site it looks like they do come with a cable.
I wouldn't worry about the quality of the preamp cable. The thing is so short it is not an issue. Also it is transfering a line signal and not a sensitive mic level signal. I would be willing to bet that a shitty cable would make no difference in the sound quality. Its not like the I-River has mogami cabling inside of it. It using hook-up wire. The patch cable does not matter much IMO.
