I got the Pipeline ET4 cable early on, and I did have to do a little sanding of the barrel on the Mikros end to get it to fit into the recessed jack. The cable is very well made. It has a goofy directional marking to make you think that there is something special about it. There isn't. Copper conducts electricity exactly the same in both directions. I sanded both ends so they fit into the Mikros jack, and it worked both ways...no directionality. The Pipeline cable has a braided cloth like cover, so for me it was just too microphonic for portable use. It is also pretty stiff. Of course, now it is modded, so I can't return it...doh! Does it provide better sound than the stock cable? Not to my ears, but others claim a slight change compared to the stock cable....better or worse, I think the only way you will be able to judge this is to drop the ~$10 (Amazon) or ~$16 (Radio Shack) for the ET4 and see for yourself. The Auvio cable from Radio Shack (below) is just as good to my ears. It is a bit shorter (3 ft vs 4 ft for the ET4) so I have less issue with microphonics even though it has the braided cloth cover as well. And, it fits in the Mikros jack without any mod. To be honest, I bought a 3ft Belkin cable from W-Mart for $4 and it works just as well as any. I think you will have to have very young ears (mine are not) and/or near perfect hearing (alas, mine is not) to detect a difference in most cables. Mine were ruined by too many Who concerts in my misguided youth.
