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

You want well shield and low capacitance.

But at the end of the day just try your best cables - you ears will tell you what works. You want no buzz hum or noise.

Does the Denon AU-340 have a bypass switch so you can run a mm cartridge through it and avoid the transformer? Cable capacitance will only affect the high frequencies of mm cartridges by rolling them off.

Some mm cartridges have a recommended capacitive load for flattest response. This capacitance is the sum of the tone arm wiring, cable to the phono stage and the phono stage input capacitances.

If the capacitive load is below the minimum for a particular mm cartridge it will have a high frequency peak. Moving coil cartridges are immune to capacitive loading.
