Up to some point you'll be helping the recording quality by using better cables. The real limiting factor is the quality of the A/D converter onboard the NAD. So I couldn't see going TOO nutty with cables for this. For recording quality, you'd only need to worry about the pair going from integrated-->cdr. You could use something else for playback.
Obviously, it would be useful to try and audition a few cables from your local club, friends, or local dealer. I imagine you would be looking for a neutral cable that doesn't introduce much of a sonic signature into the recording. The goal of the cable should be to stay "out of the way" of the recording - here especially so. I have heard that some of the Cardas and Analysis Plus interconnects are neutral, but I haven't heard them personally to recommend either. Both can be had for reasonable prices ($100-$350/1m or so, depending on model)
What do other people use in this setup?
