I have. My preference is the stock cable.Has anyone tried the tri metal LC-RE PRO cable with the FD-7?
Context:
(a) I am more mid and treble centric and so that is why my preference is with the stock cable;
(b) I tend to use the FD7 for more critical listening and the FD5 when I am out and about and want more of a fun tuning; and
(c) OOTB I find the FD7 more reference (neutral) while the FD5 is more V-shaped.
I therefore prefer the stock cable with the FD7 as I find that that brings out the reference nature of the iem more than the LC-RE Pro does. On the other hand, what the LC-RE Pro does is to add more warmth to the overall sound signature and smooths out the treble and this works well, and is now permanently paired, with the FD5.
I am not saying that the LC-RE Pro does not pair well with the FD7. For my use case, I find the stock cable the better pairing. YMMV of course!
