Recommend amp to drive Totem Winds?

I'm looking for recommendations for an amplifier (solid-state, integrated) that would be a good fit to a pair of Totem Wind speakers. I've heard that the Winds can be hard to drive, so I'm a bit concerned about what amps will/won't be up to the task.

The Winds are rated at 4 ohms impedence, 87 dB sensitivity, and 250 W maximum power. In general, is it OK to look for an amp that will produce slightly less than 250 W into 4 ohms? Or should I look for an amp that provides 250 W, or more than 250 W, into 4 ohms?

Brands/models I've looked at include:

Simaudio Moon i-3
Simaudio Moon i-7
Krell KAV 400xi

I'm certainly more than willing to consider others, of course.

Thanks in advance for any help/suggestions/opinions....

Cheers,
Barb
