I've extensively auditioned a number of integrated amps, including those that you've mentioned, as well as the Plinus 9200, BAT VK300 and McIntosh 6900 for my Totem Forests. I liked the Krell, BAT, and McIntosh very much, but each produced a very different sound. I have also listened to the Pathos Logos on a pair of Proac Response 15s. All of these amps had ample power for the Forests and all sounded good to my ear. In the end, I purchased a DK Design MkII for purely subjective reasons. (I use the Forests with Speltz Anticables and an Arcam FMJ cd 23 in a mid sized room (16 x 23 x 14 vault)). You might consider expanding your auditions to the Plinus, BAT, Mc, Pathos, and DK for the Forests. Worthwhile to audition any of these amps to find the one that works best for your tastes.
