Sakura Systems OTA Cable Kit

Please help. I got the Stratos kit about three weeks ago and immediately set up the speaker wires. My observations were pretty close to everyone here (boy, do horns sound good now), and I have made firm believers out of a few cable doubters (including, to a certain degree, myself). I must, however, be the biggest idiot in the world as I can't seem to get the interconnects together. I have assembled a pair (actually a pair and a half) and with a little 'wiggling' of the plugs can get one channel to fire. When I try to hook up the other channel, I can't get any sound at all despite all the 'wiggling' and repositioning that I try. Now it's not simply the run of interconnect or the terminals as I can switch the cables or switch the channels and can almost always get one channel to work. I've already broken one of the machined white pieces and have about two feet in scrap on the floor and I'm at my wits end. At this point, I really wish there was an option for the mechanically idiotic to have the interconnects pre-assembled.

Thanks DK, I'll give it another go with the extra loop on the center post, I hope this will solve my problem. I'm almost too embarassed to ask this, but just to make certain the cable should go from white to white and from black to black, right?
As far as the speaker cable is concerned, I really have enjoyed going back and listening to my favorite recordings with it installed. I don't speak fluent audiophile, but what I have observed is that trebly type instruments (*especially* horns) have more of the edge that they have in real life. More important, though, is that everything just seems to be 'faster'. It's hard not to tap my feet and even super droning ambient type music (Yo La Tengo's latest effort or anything by the American Anolog Set, for example) seems more vibrant and alive. Admitedly the cable I replaced was nothing special (Tributaries copper and silver coated copper braid) but this was as significant for me as replacing my PSB's with Triangles. Associated equip: Ah Tjoeb 4000 into Jolida 302A via Tributatries interconnect, into the Stratos, into Triangle Zephyrs. Actually, if you're familiar with the Triangle line of speakers I think that this cable does well what I like about those speakers.
