The chassi screws on the PSU are a good start.

I used the banana->small spade chassi ground connectors. Just loosen just a nudge so you can press in a small spade then secure it firmly.

The ebb and flow of the music is improved. Faster but more smooth. Less sibiliance.

Star chassi grounding is nothing new btw. But this was easy enough and the tritons have their technology to quiet the ground as well. Denali do not as it is only live/neutral dampened by the NIC’s but still star chassi grounding.
