I suggest you pay for those expensive connectors, and make your own cables. I don't think there's any competition who makes the same thing cheaper.
Otherwise, you'll need the cable David bought, but it's hideously overpriced like most Schoeps accessories. The total materials cost of that cable is no more than $100, even if you use the Schoeps KS cable stock.
The other option is to exchange your CMC 1 L for CMC 1 U. XLR connectors are cheap, so you could make a Y cable of similar length for about $25.
