While talking with the designer of the Audio Aero CD player output stage at CES he *very strongly* urged people to use a balanced interconnect from the CD player to a preamp or amplifier. We currently use RCA, because that is what we have, and it works fine but if your McIntosh supports balanced inputs, and you have a choice, you might want to go with balanced.
As for brand of cable, Acoustic Zen is nice and does have a following. With the Audio Aero and McIntosh both being tubed, you might also want to try something a little faster and cleaner sounding like Nordost - but Nordost will also be leaner as well. As usual, you've got to choose *your* favorite flavour out of many tastie treats :-).
