Default Grounding Hypex Amp Build

Having built a Hypex Amp and reading other posts is there a audio quality difference on where the amp is grounded?
Using: 2- NC400 / SMPS1200A400 / Hypex Connection board
Ghent single chassis stereo case
The amp is dead quite on 105db horn speakers.

I grounded the Nampon and the XLR's at the grounding post by the
AC power Plug all together.

My question is will the amp have an audio quality improvement going back in and grounding the XLR's closer to the jacks and shorten the ground wires or is
it just to control hum?

Thanks for any help and thoughts.

It's all about minimising the ground loop. A loop acts like an aerial and the most likely thing it will pick up is mains hum. It will pick up other interference too. The only way to know if the audio is being affected is to measure it. But if you can't hear any hum, it's probably fine.

All your Hypex parts do not need grounding (by means of protective earth). The NC400 is balanced, thus audio signals is not even referenced to signal ground. Just use protective earth for what it is meant for: protection. Connect PE to your chassis and thats it.
