How important is the cable between the SUT and phono pre?

I know when using a cable between a MM cartridge and the phono pre it's very important to take into account the capacitance of the cable for cartridge loading.

I don't recall seeing a discussion on the importance of using low capacitance cables between a SUT and  phono pre.  

I picked up a Denon Au-340 to replace my Denon AU-320 in my system and the AU-320 has built in cables that run to the phono pre, hence my question.

Is there a way to figure out the capacitance requirement for this cable or is it not that important? Will a good shielded cable work fine?

I don't want suggestions on some high dollar cables, that will never happen. I have about 15 or 20 pairs of cables that I picked up over the years, I can always go through the pile and measure the capacitance if necessary.

Thanks

It has a bypass switch but right now I'm just using various versions of the Denon DL 103 cartridges. So 

MC all the way. I have plenty of good shielded cables so I should have what I need. 

Thanks

"MC are said to not be sensitive to capacitance, but the problem with a SUT is that it reflects the capacitance of its output cable times the SQUARE of its turns ratio. That’s enough capacitance that it WILL start to affect the MC cartridge."

 

Can you point me to some more information on this? I was searching for information and found nothing to indicate that this was a problem. I've read that the cables from cartridge to SUT didn't need to be particularly low capacitance but nobody talks about the cables from SUT to phono pre.

Thanks

So this AU-340 sat on the sidelines for a few months and I just hooked it up with a nice quality 18" shielded interconnect. Wow, sounds spectacular with my retipped Denon DL-103S that Steve at VAS did for me. Used an elliptical stylus on the original cantilever, don't even have the alignment spot on yet. Listening to Willie Nelson, never sounded so good!
