Leo,
It sounds like you haven't even heard the Morrow MA-4 interconnects, so if that's the case, why are you torn between them and the Goertz?
There's a used set of 1/2 meter MA-4 interconnects on the Morrow website for $223.30 right now. Why don't you just buy them and see if they work.
It seems like there's quite a few Audiogoners who like the Morrow cables, so if you don't like them you can sell them. The 1/2 meter length might be a problem with the resale though.
