Can the M-200 handle a 2-ohm load?

I'm think of running a HSU TN1220 sub with the M-200. The sub specs 200-250 watts at 4 ohm. The M-200 can achieve those specs. Dr. Hsu himself e-mailed me asking if the amp can handle a 2-ohm load. Any comments?

I am also interested in what the lowest impedence load the M200 could handle. I would like to run a 3ohm load myself.
