Spectron Mk II, is it really that good.

I have been researching several of the new “green”, compact high power class “D” amps. It seems that the new version of the Spectron Musician III SE Mk II, is pretty much considered the king of the hill. Having no dealers near buy, I can’t actually listen before buying. My question is, there seem to be lots of happy owners, but are there any current, or former owners who are, were, not happy with the amp, or is it really that good.

FYI: Current amp is a PASS, X-350.5. A monster to move around, hot, cost a fair amount to run, but a wonderful sound.

All comments and opinions welcome.
