Thank you all for the advices! I so far tried 5m of my 2697 cable I had
laying around and discovered no significant difference in quality and
noise.
Meanwhile discovered this website:
http://www.mogami.com/e/cad/mic-cable.html
It has the attributes of mogami cables pre-programmed. 80' (~25 m) of
2697 will lead to slight attenuation in 20 kHz and phase alterations:

0&Rr=3D600&name=3D2697&R=3D0&C=3D0
Whether the phase-shift will alter the sound in some noticeable way,
that I don't know.
I am thinking that I might use some more rugged cable though.
And I am also switching to mini-xlr on everything, much more reliable
indeed! Which brand do you use? I tried Switchraft, Amphenol and Rean
and the last one is winning so far.
I also tried no-name type off ebay (it seduced me with full metal
construction) but it turns out it gets stuck in one XLR input connector
and is hard to remove.
Regards,
Jonas
