Re-cabling has been brought up earlier in this thread.
A couple of us are currently using and reportedly enjoying the AudioQuest Pipeline ET-4, with solid core SPC conductors. $24.99 at Radio Shack.
The plug diameter to the Mikros 90 cable input is very small. My Pipeline just barely squeaked into the recessed hole in the MLs and made full contact with the jack. Others have not been so fortunate. doctorjazz gave up trying to fit his Pipeline, fearing damage to his headphones and/or the cable. PredatorZ had to whittle down his plug barrel (by 1.2 mm) to get it to fit. I tried a slimline Belkin cable the other day, but even its input plug barrel diameter was too big (and the barrel was metal, with absolutely no give).
I have not seen any after market cable yet that looks like a shoe-in for the MLs. (Just remembered that there is a picture somewhere along this thread of the Mikros 90 fitted with a blue "iConnect" branded cable, too.) I have contacted Ted (Headfood) and asked about a custom UPOCC silver cable. If the silver cable is possible, I may also ask him to build a copper one. I have always preferred silver, as long as it is "done right".
The barrel diameter on the stock input plug is pretty small: about 7/32". Another option would be to drill/machine out the recessed access hole on the headphones themselves in order to accommodate a wider range of after market offerings. I may contact ML and ask whether they would be willing to do that for me. A slightly enlarged input access hole would then give the ML user a host of after market options.
