The monoprice page had couplers on it, so I do not think he wants couplers. What I think he wants is a long male to female RCA cable, aka RCA extension cable. That way he does not have to use a coupler.
Really, it is 6 of one, a half dozen of the other. Both work just as well. IMO, the coupler is better because they are more commonly used so you can get higher quality ones.
But for the RCA extension cable, you can find them here , here , here , and here .
