My recommendation is what it is, and just because other types of equipment use them doesn't mean I endorse them nor believe those wouldn't sound better without them.
So are you saying that in your opinion it's not a requirement to have a fuse?
Hypex (SMPS) has a good RFI/EMI filter inside. Maybe a Schaffner filter ruin the sound.What RFI/EMI filter incorporates your design?
Would you elaborate on this warning a bit more? I am using a 24V SMPS (laptop brick). Are you saying I need to discharge the bricks caps if I disconnect, and reconnect power?? Is it safe to unplug the SMPS from mains, but leave it connected to amp, and then re-plug back into power mains? UNDER NO CIRCURMSTANCES connect the PSU board or any other power supply to the amplifier board with a charge in capacitors, or without a switch for say batteries. The spark that can occur can toast the transistors. If you test the PSU then you must discharge the capacitors before connecting the amplifier to it. There’s a place on the PSU board for a discharge resistor (I haven’t defined a size, because it varies for the wide use of the Antipole, 10kohm would be fine for this project)
Technically so long as you isolate the chip tab from the heatsink, there's no requirement to even ground the enclosure because of the complete isolation. But you can do so anyway (I did).
i was going to ask about the reason for isolating the chip tab from the heatsink ... the drok tda7297 that i got from amazon isn't ... can someone elaborate on the reasons for isolation? it also doesn't have heat sink compound, which i didn't like, so i added my own, which was when i discovered that it wasn't isolatedthanks!
The main is increasingly dirty by the cheap switched transformer connecting.

i'm in the process of building/planning an enclosure ... i was thinking of using wood ... is that a bad idea?
I came up with a layout I like more than the demo, thought I'd share with you all considering enclosures. You'll notice I didn't include a switch because location for that is your choice. I kind of like them in back,
