Forgive me for not being clear. Here I was referring to the 000 cable that is plenty stiff enough in the wire. The stock is not stiff like that I quite agree, and not suitable for holding the iems in place.
However I much prefer the total flexibility of no memory wire more than the "semi" memory of the stock wire and the stiffness of the proper memory wire the 000 provides. This is my taste for comfort only and may not apply for all.
Milarepa, I think its wonderful that you have found a cable that you adore and makes our 334s sound better for you. For me the 000 was a big upgrade in sound. The stiffness of the cable really is not a issue for me and microphonics of the wire which means to me, when it rubbed transmit sound, is the lest issue of all.
I would like to get a cable which termination would help with the placement of the shell in my ear stay put. Now once a 1/2 hour or so, I find myself pushing the iem in and would like for that not to happen.
The sound nirvana you've found is very encouraging to me and I'm sure to others, that our hopes and beyond can be achieved. Right On my Brother!
