Talking about Crown. I actually didn't realise it is part of Harman, and interestingly so is Mark Levinson .....
according to this review Crown has delivered a lot of knowledge to ML with regards to their class-d amp No53

70V is safe. You will sense something when touch it, but it is safe.
Isolation is not always help. In my country 220V power line is used by government. The cables has thick isolators and connectors is much better than speaker any connector. But it is already many people death in their home caused by electrical shock. Also few houses gets burned by electrical failures.
If the government giving two choice between 110V and 220V, I am afraid there will only few people choosing 220V.
Do not forget that failures are frequently happen. Even me, has shocked many times, and two of them I feel that it will kill me.
Respect Electricity or you will be forced to respect it by other means
Nops, its Onto aban's dreaded [hair raising]past experience in high voltage electronics that he want to stick to under 100V sweet creampie

Onto Aban , What will you do for PFC when its boosted output voltage is around 400VDC
onto aban, you make it sound like electricity is something new

I built a class AB converter to generate 20KV 1KHz sine wave from 400Vdc.
Now that's high voltage

I didn't had the necesary patience to read all the posts but like Eva says in the first posts you need a serious gate driver for that. The gate driver is not composed only with 2 Cmos transistors... Also there are too many mosfets in paralel maybe the idea should be to increase the voltage not the current
230V mains uses 4 times less copper (or aluminium) than 115V for the same power capability and losses. Copper is a semi-precious metal, and it's getting more expensive year after year due to the high demand.
Then again, depending on skin humidity conditions, lower voltages may become lethal too.
230V is probably going to become the worldwide standard within a few decades.

seems everyone here disagree with my 70V audio rule even in Java. ,,cars and airplane coming here too.
But 70V class is the winner in this world.
Do one thing, plug the 70V lines in your ears and become an angel and rule the universe by wandering till eternity.

since it will have residual breaker on it, you may play it in your ears. without wandering people
