Do you have the One Zeta's now? I run mine with a Bel Canto digital amp, and my dvd/processor is primarily a home theater unit and even so the sound is vey nice, as I tried to balance a system that visually did not overpower the room (hard to do), while also tying to get the best sound. As you said, they provide great resolution and a nice wide soundstage. I agree with Jaybo, I am sure your Krell will mate well with them. My amp is 150 watts dual mono and it is plenty to drive them. The Aliante's I believe have a sensitivity of 88db or so and they like a little power.
However as a word of caution these speakers are getting a bit aged, and I don't think Aliante is doing much in the states now, so if there is a problem... It could be a problem.
