Default Grounding scheme when having more than one pwr supply

I would like to get your opinion on the recommended grounding scheme for an amplifier that has more than one power supply with separate transformers.
Let's say 2 transformers with the corresponding power supply board each.

Do you mean stereo, or a dual mono amplifier, or a single channel with multiple supplies?
Can you post a specific schematic?

With grounding, a single point ground is usually considered the best approach.
