High end Class D amps?

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?

The problem with Putzy's quote is that many aspiring a'philes cannot afford class A $$$$$, not just the initial purchase, but also the cost of electricity to run it, and cool it, especially if the owner lives in a warm climate, as I do. Way back when (some 25 years ago) I owned a Kinergetics KBA 75 (all class A), which was amazing, and the only amp of many I tried that could grab a hold of my Genesis Vs and make them play properly. Sadly I blew it up changing power cords without letting the caps discharge


Next, consider most rooms are far from ideal as listening rooms, meaning playback is compromised from the get go. My most recent Ds were Audio Alchemy DPA-1, PS Audio M700s; both sounded quite good, but lacked the drive my large room requires. The back wall (behind me)  from my listening position is 3 sided floor to ceiling glass ~ 15ft away, so zero back wall reinforcement

My EVS1200 (~1200 wpc in 4 ohms) does a great job of conveying all the musical ques to my Emerald Physics 3.4s, though over the weekend I reinserted my 2 SVS powered subs which helped considerably to fill the space with a decent SPL

I am envious of the Black Ravs. I heard them here. They were extraordinary, especially the doubles, but too rich for my blood
