I didn't read the whole thread but I would like you all to know that I've been using the Hegel H160 amp with KEF R900 speakers for the past 6 months. I'm very happy with this combination, it just sounds fantastic. Before I bought the Hegel I tried a Yamaha A-S2100 and a Marantz PM 11S3 with the R900's, but the sound of both of them could not compete with the balanced sound of the Hegel. The bass is deep but controlled and the treble is high but not sharp. I was pleasantly suprised when Hegel mailed me that they had used the combination of the H160 and the R900's in several demonstrations because of it's smooth sound. So for those in doubt which speakers to choose for their H160, I would say that you can't go wrong with a pair of R900's.
