I would agree with the Transparent cables but I must dissagree with the Krell, as every B&W system I have heard with Krell is harsh (bass control in spades but harsh in the tweeter).
The ARC stuff would sound nice, you could also consider a Conrad Johnson Preamp if you preferred a bit of warmth on those B&W's
