Classe CA300 vs. Classe CA2200?

I've been using the CA300 for a few years now and am curious about the newest series from Classe. The CA2200 is 2 channel with 200 watts per side while the CA300 has 300 watts each. Doesn't look like they're making a 300 watt stereo amp anymore. 200 watts should be plenty for my speakers though. Anyone done a comparison on these? Any significant sonic improvements?
