All output voltages on the smps600n400 are missing, the amplifier turns off after 8 seconds, and the stendbay indicator flashes.
So there is an output voltage from the smps for those 8 seconds? How about nAMPON, nFATAL and SMPS Standby?

What do you measure at pin 31 and 35 from each NC500?There is no damage to the radio components on the power supply board; the fuse conducts current.
There is no voltage with smps600n400 in these 8 seconds
Thanks for the link, the nad m22 uses a different smps power supply
Hypex NC400 amp is a completely redundant solution. You do not need to spend so much of your money to get quality sound in class D.
Graphs and figures in the review are only good for measuring devices, but not for human ears, even if we got much worse result, our ears can not distinguish the difference.
Such high power is not needed for a good home acoustics. Good acoustics works fine, consuming only 5-10 watts.
Depends upon the speaker and peak levels desired. My average level is about 3~5 W but to reach 100 dB peaks requires about 150 W into my speakers at my listening distance. It has more to do with the speakers and listening distance from them than the room.
FYI my Mark Levinson switching amp that is rated at 1000 watts into 4 ohms has a linear power supply. To give you a sense of what that does to the design, the thing weighs 75 KG or 165 pounds! And that is for one channel.
I have no measuring equipment.
I do have a stereo amplifier using NCore DIY modules with their 1200 watt power supply. I have never heard any compression or clipping using there with normal speakers (87) even when testing them at loud volumes. I have had two power supplies burn out in 3 years. Amps are on 24 hours per day. Both times the power supplies were replaced or repaired at no cost (other than shipping) by Hypex. Obviously a heat issue but no observable problems in real world use (sound quality - - not heat issues)
Oh yes .... such quality amplifiers in test and such a low-quality implementation in practice ... is not there a trick? ;-)
