The male wall connectors, yes, those can be rated at 20 Amps, but are you pulling even 1/20 of that? No matter, just wanted to point out the IEC connector.
I have a few power cords, and can easily say that my $3 DIY line filter made a much bigger difference than the $25 Iron Lung power cord that I use for my speaker amp (I also own a Quail).
Hopefully when I build my VenHaus power cord with 3x 12AWG SPC, I'll see a nicer change.
