Cable capacitance and length?

[ahblaza]

Hello,
I need a 25 foot length of stereo interconnects from phono preamp to line level input on receiver. I know that lower capacitance cable is needed. I have found 2 different Belden cables, capacitance for cable 1 is 17pF/Ft., cable 2 is 12.2pF/Ft. Cable 1 is half the price of cable 2. My question is can I get away with the less expensive cable with this distance, or is that 5pF/Ft difference that important. My phono preamp also has adjustable gain for the extra length cable, I was told I could lose 10dB with the the long run, so how important is the lower capacitance cable if any? Thanks in advance.

You biggest issue is going to be hum pick up, for that reason I would use the better quality Belden cable.

Also, don't run the cabling parallel to any other wiring, especially electrical power. If it must cross past near anything, cross at a right angle.
