need help choosing between line level cables

I'm looking to buy cabling to run line-level stereo audio through the 
walls of my home (tape mon output of one receiver/amp, thru walls and 
into another amp). It's for an outdoor stereo so I don't need the 
end-all-be-all best sound, just decent, humless audio. The most common 
cabling choice seems to be Belden 9451D. Another Belden cable, 8723, 
looks identical--I can't see what the difference is. Does anyone have an 
opinion on which is better? I'd prefer the 8723 since I can find it sold 
by the foot, the 9451D is only available in bulk.
