Danheather-I misunderstood your "problem" I don't think there would be much lost by doing so, but the possible benefits of BNC would be negated. I know Pure Note makes some of the cables you describe(different end on either side of the cable) you may want to check them out, they seem to be a highly regarded cable at a remotely afforadable price to most. There was also a thread here not too long ago about silver vs. copper digital cables you may want to check that out.
Good luck,
