Having owned both KEF speaker (107.2's) and Aragon stuff (24K pre/4004 MkII) I can tell you that I didn't like them together. Both are fairly bright, together they were fatiging. I tried different cables to tone it down, but it still was harsh in the high end. I'd go with something a little smoother, say a Proceed amp2 or HPA2, or if you can afford it, go Mark Levinson. It will really help smooth out the high end of the KEF's.
