High end Class D amps?

I have first watt J2 and F6 and also have Theta Prometheus class D 400 watt monos.  About as polar opposite as you can go.  I have great thoughts of both he first watt and Theta.  For sure class D can sound good anyone who lays a blanket statement over class D amps sounding bad period just ignore them.  Find out for yourself.  There are many pluses to them namely that they don't heat the damn house up.  I don't care in the winter but in the summer hot amps are a drag.  Can't be a tree hugger and love class A can you? maybe you can do carbon offsets to make up for it!  Also all this stuff about Michael Fremer being a shill for PS Audio I'm sure these keyboard warriors on Audiogon Forums are so enlightened I'd put a lot of faith in what they say.  

....yup, devolved into a variant of the old 'IC/speaker/AC line type/taste squabble.....with random snipes...*sigh*

Try using a wooden j-box in your house and telling the electrical inspector he is an idiot because the wires inside it are insulated.

There is no "fire hazard".....same with having cotton covered wires inside.

... It won't work with the safety inspector nor UL, ENEC, etc.

All those protections on the supply are not definitive protections from catastrophic events. There is a reason why electrical products are encased in metal or fire retardant plasics.

A catastrophic event ..he he... is when you win the super duper lotto.  That is about the same odds as a wooden backed amp has catching fire.  When have you heard of an amp that caught on fire? (I have read about 2 in over 50 years....and no bodies house burned down).. And if it did.......did it have wood on it?  The answer to the above is practically never and never.  We worry about silly things.  By the way, fuses do not help with lightning.....the fuse blows and so does your component.  Maybe you mean putting a bomb in the amp?  That certainly would be catastrophic.  Maybe we can get back to how various amps sound instead of worrying about a wooden back plate.  People have different philosophies about what is safe.......some would never do anything without someone else telling them it was safe.  Some rely on their own intelligence.  Some hide in caves.....some dance in the light.  Fear and ignorance is what keeps people from being happy.  Trust your self....and dance in joy!

So I'm confused about the little Nuprime ST10 amp (which has gotten rave reviews btw). Its output is rated at 150wpc at 8 Ohms and the same at 4 Ohms(??). Plus it has a toroidal transformer. Does that make it a hybrid of sorts?
