From what I've heard about the Super Amp it should be a great match; particularly since you have the luxury of switching to your other system if you run out of power!
As with all tube amps, I would pay very close attention to vibration control for your AES Cary. I've posted a link elsewhere to my contraption that worked well for a tubed cd player; should work even better on an amp. (Think about it for your cd player too if you haven't.)
Van den Hul is a pretty traditional match, but you might consider silver or coppper/silver cables as well for tubes.
My experience with stands is that they must be solid and non-resonant, but the recommended height is a topic of some contention just now, as you've likely read. See the ongoing
thread for more info on that. Since you have the older De Capos, the tweeter may be a little 'hot' compared to the 'i' model (this is my impression), so keep that in mind; but again your results (with your amp) may vary.
The Arcam is a well-regarded player; but something tells me you may be looking into upgrades once you really get the DC's dialed in...
