Thanks for that information. 600 ohms is too low an impedance for the mic p=
reamp, tho. For example, the LS-10 mic input is specified at 2000 ohms. Rec=
omputed for that input:

0&Rr=3D2000&name=3D2697&R=3D0&C=3D0

Which is a little worse but usable in an application where weight and size =
are the most important factors (backpacking).

Mogami 2697 is as robust as a flexible, miniature cable can be. Never had a=
 problem with it.
