The McIntosh will be the better fit if you are looking at softer tones. The Krell will be more agressive as will the Odyssey. Read the review in the Absolute Sound regarding the Odyssey. Yes, they said it was good, however it tends to be tipped a bit at the upper end.
If you were not impressed with the Krell, look at the McIntosh. Let your ears decide, not our writings or our recommendations of amps we have never listened to. I have heard Krell, McIntosh, Acurus etc. and can verify the Acurus is tending to go towards the brittle. Their whole line does that, including the Aragon line. With your B and W speaker, you would most likely want a big fat sound. McIntosh gives you it. But try it, it still might not be what you like. Might go too far in the direction. Keep looking and LISTENING. That is your best guide. Each ear is different and no matter what I like, it might not be what you like. However, I would only recommend an amp I have listened to.
