XLR cables, worth buying higher end?

Any diff between microphone and interconnect xlr cables?

seems mogami xlr used for interconnect seems a solid choice.  Not hearing much to be gained spending $500 or more for a 3ft xlr pair.

and saying this after spending $3k for speaker cables

Problem is i need two xlr pairs since i am using a stereo tube preamp bypass between a processor and speakers.

my system is revealing.

Mogami gold aes xlr seems to be the clear winner. A very credible player, widely used by pros.  

$65 per cable.  Will try.

abit nutty to spend $500 or more.
