Is a switching psu suitable for such high current peaks? Nevertheless awesome! Tell us more about the prof. speaker connectors!
Amplifier power: 8 ohms / 300 watts, 4 ohms / 600 watts, 2 ohms / 1200 watts/
Current rating 40 Amp continuous, 50 Amp audio with 50% duty cycle:
NLT4MP-BAG - Neutrik
Current rating 40 Amp continuous, 50 Amp audio with 50% duty cycle:

I'm a huge fan of the Speakon and Powercon connectors! 🙂
I'm with diyralf on his question.

At first, I lol'd, however, it's actually not a bad idea on switching supply DC lines.
Uh, no. That is amazing attention to details. To take every precaution to reduce noise.
Ok, nothing ventured nothing gained..
here is the latest version of my inductance loaded Class A amplifier:View attachment 660390
If you look closely you’ll see the transformer primary is taped up, that’s because I’m using it as an inductor, only the secondaries are used. It’s one of a pair BTW.
Here’s a board nearing completion:

I can’t remember why I took this:

The heat sinks are ‘live’ - to avoid isolating pads - so they are secured to the inductor using plastic screws and stand-off’s.
Oh, I should say, from a 6V supply (I use SLAs), it produces 6W into 8 Ohms at 0.003% THD - according to LTSpice. I’m toying with the idea of reducing that to about 4W - not sure.
