Creek Destiny -- Maggies?

Hi all. The amp I've been using to drive Magnepan IIIs has died and I'm not sure I will be able to get it repaired (importer is out of business and I understand no one can get parts). Of all the amps I might be able to afford used, the Destiny seems most interesting. However it's only putting out 180 watts at 4 ohms, which seems pretty borderline. Anyone have any experience with this combination? Thoughts? Thanks.
