I've recently discovered Plinius myself. Since you make the 200 watt distinction, I'd recommend the Plinius 8200MkII wholeheartedly.
The midrange is very smooth, and quite forward. I am torn between the absolute linearity, extension, deafening silence, lightening speed, and tube midrange of the Nixon amps. . And the excellent, forward midrange, and artificially beautiful highs of the Plinius.
