I've ordered two cables from OC studio with the best mmcx plug there is I'll report back once I have them. I think the issue with t8ie isn't from the male side but from the female side which is what is inside the actual IEM body.
I've had minor issue when I use the stock cable of the mkii with my other mmcx IEM.
The problem lies with both.
As you have hear about my problems with the Xelento.
out of the box cable, R sound cracklys and disconnects, L is OK.
second exchanged cable, same as the first.
third exchange cable, R is ok, but L is loose and turns.
in all case connecting the R male to L females with all cables, the problem is the other way around.
in all case the connection has a soft double click, and not the usual single clean click, a few iem shops advice me to exchange the whole IEM and cable, did just that and it was found that both the female and male has problems, got a replacement, came in a bubble wrap and not a box, this time a much tighter connection for both L and R, although the R side does still have the double click (L has a tight clean single click), connect the cables around L to R and R to L, and the double click is on the L side iem, tried the old cable on the new replacement IEM, and it is very loose.
The replacement I got is perfer alright, whiles the cable on the R side still have a minor problems, but no crackling and not loose, shows it's a cable problem and not the IEM for this new set.
I have asked them to contact me when they get some stock cables in, and at USD 45 each, pretty cheap, and they do sound very similar to the Linum cables, even the Linum cables does not work well with this IEM. After my trip to Japan I will probably pick up a pair of Final Audio Lab II cables, or if they are cheap in Japan I will get it from their.
